Can someone post a Cliff's Notes version of what has been going on to-date?
If you could explain it like I am a 10 year old that would be appreciated.

Specifically: what was fixed, new problem introduced, Infocus' official stance on moving forward, option to upgrade/downgrade firmware at home, etc.

Just figured the info should be in the thread asking people to sign the petition.
Personally, I'd be more than happy to sign if I knew the details. And I think a case like this should be signed by more than just SP4805 owners ... because (potential) lack of support/firmware upgrades could send a bad precedent overall in the HT market. Not just on this specific model.

The 4805 loses the signal when switching between standard def and high def forcing you to reach for the remote and hit "auto image" every time you change channels. The firmware upgrade they issued addressed that problem but causes a flickering, so most people are suffering the inconvenience rather than risk a flickering image. There are some other improvements but I don't recall what exactly they were. It's been a loooong time between fixes and InFocus is responsible for this.

I put my X on the Petition.

Wow... That is a terrible bug! I can't believe people buy the 4805 with that bug. I hope they fix it ASAP. X1 users used to have that problem until they added the synx checkbox to the firmware. I guess someone at Infocus forgot to add that to the 4805.....

Done!

I have signed the petition. I'd love to see a fix for this problem.

Done.

Done...I think. Too many frickin other things to site wanted me to do after submitting the petition.

Done! Just click NO for all the other crud!!!!

Yup... I signed it and I don't even own the 4805. :D

Signed too.

A quick message to InFocus: You can choose to ignore those of us that bought your entry level pj. But I guarantee you that my next upgraded pj will not be an InFocus. Plain and simple.

Done! How in good conscience release firmware this flawed? Great PJ and don't regret purchase, but c'mon Infocus...get your sh*t together!

I hope InFocus pays us all the attention and respect we deserve. This is how a company wins or loses repeat business.

Is there any way to see how many people have signed so far?

Signed.

Is there a way to go back to the first firmware? I'd much rather have to hit a button on the remote than to have a messed up picture.

The ipetitions.com website seems down for me... I will post updated statistics once I manage to get in.

The link to the original firmware can be found here:

Thanks to everyone who was signed the petition.

I have updated the original post at the top of this thread with current status of petition. I will try to update this every Friday.

I would like to gather at least 300 signatures before formally sending this to Infocus.

I made an inquiry about the firmware to infocus. This is what they said:

"We are still working to address the flickering issue and hope to have it resolved some time in the near future, however we do not have an ETA for when this issue will be resolved."

So...they're still telling the same 'ol story eh. They told me the exact same thing 6 months ago! :mad:

x marks the spot... I have not upgraded. I do not mind hitting the auto image button... But, will be nice when I do not have to do so...

Mine doesn't do that. I'm using VGA, is that why I don't have the problem? No upgrades, purchased in December 04. I'll sign the petition but I don't think I'll fix what ain't broke.

Thanks for the Cliff's notes Martin!

On a side note, you may want more than 300 signatures if you really want to open some eyes. From what I am reading from one industry reporting company (TFC) ... over 10,000 SP4805's have been sold since released.

Obviously this number would be low because there are some dealers not reporting to this source.

But, then again, 300 happy customers thinking about upgrading in 3-5 years might be all they need to put some extra effort into the upgrade?

In any case, best of luck to you guys!

I agree.. 300 is too low, but it has taken 10 days to compile only 105 signatures, in what I consider to be the prime source on the Internet. (AVS)

If you guys can think of any way to attract more people to sign, please let me know!

Just an idea ... I'd post the link in the other forums as well (projector central forum, etc).

count me in.my auto image button is starting to wear out!! :confused:

Get them to offer a lower power mode with an even quiter fan speed, too.

All,

I would like you to know that there will be a new version of ScreenPlay 4805 firmware posted soon on our web site. While there are important changes in this new version, it does not have a fix for the issue that has been reported here which involves momentary flashes that appear in the image at random intervals. Some have called this a flicker issue, but it is not related to and should not be confused with lamp flicker.

I want you all to understand that we have been working on fixing this issue since it was first reported to us months ago. There are teams both at InFocus and Texas Instruments working this and everyone is frustrated that we haven't been able to provide a production-worthy solution yet. Pending such solution, we have looked at every option available to us including writing an enhanced version of software based on the original software release, but those software libraries are incompatible with the enhanced functionality of the new releases.

We will continue to work on this issue and will try to provide a solution quickly.

InFocus does appreciate the contributions of this forum, and we try to monitor it on a regular basis. Although we don't post very often, we do listen to you.

Glad to see infocus is not ignoring this issue. What other fixes will there be in the firmware update? Could you provide us the correct gain/offset settings to set the 4805 to Video DVI levels?

PLEASE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Bob Willaims from Infocus has posted an update to the issue on this thread (Thanks Bob!)
Certainly good to hear that the issue is not ignored.

Not sure if it is worth to continue gathering signatures for this, given Bob's message. Regardless, I have updated the first post with stats.

gnolivos, perhaps you should send the petition and a friendly note saying we are aware that Bob Williams and co. are working on it and greatly appreciate that, only it's been a long wait already and we're worried that by the time it's fixed the projector may be near the end of it's lifespan..

Even so, this will certainly play a role in my future upgrade purchase decision!

Thanks Bob. Nice of you to stop by.

Forgive me- I've been away for a while. What is the latest firmware currently available?

I don't think I have either issue (auto-focus or flicker)- is that possible??

Very much possible, some people are not seeing any flicker.

4805!

does the earlier post suggest the 4805 cannot be used out-of-the-box as a PC monitor connected via DVI?

I believe it can- with a Mac G4 anyway.

does the earlier post suggest the 4805 cannot be used out-of-the-box as a PC monitor connected via DVI?

Yes it can - the 4805 defaults to PC DVI rather than Video DVI. The post I think you were referring to is JaPhule's questioning of proper RGB gains/offsets to achieve Video DVI to prevent banding.

i'd like to understand the resolution of this (i.e., how many mirrors it has)

if you play widescreen thru this projector do you get 480 pixels of vertical resolution within the image or does it de facto "letterbox" within 480 pixels (of 640 x 480). relatedly, if you use it as a PC monitor, do you set the PC resolution to 640 x 480? does it somehow know not to scale at a certain resolution?

also, i saw it at costco and there was no indication of a DVI/HDCP input. the box said component or s-video. is there a DVI input on this thing? is it HDCP?

if you play widescreen thru this projector do you get 480 pixels of vertical resolution
Yes you get the full rez as the rez is 854x480.


you use it as a PC monitor, do you set the PC resolution to 640 x 480? does it somehow know not to scale at a certain resolution?
If you run a DVI cable to it you can run it in 848x480. If you feed it ia 640x480 signal it will only light up 640 horizontal pixels, then with the aspect button you can stretch it to fill the screen.



is there a DVI input on this thing? is it HDCP?
Yes it is fully HDCP compliant and the digital plug you seen is called an M1 port. You will either need to buy a DVI-to-M1 adapter or you can buy a DVI-to-M1 cable.


peace

does the earlier post suggest the 4805 cannot be used out-of-the-box as a PC monitor connected via DVI?

I must note that if you want to use DVI with the 4805, you have to buy a separate M1 to DVI adapter, the 4805 only comes with a M1 to VGA/USB cable.

signed

Signed.

All,

I would like you to know that there will be a new version of ScreenPlay 4805 firmware posted soon on our web site.

Soon meaning......

I'm becoming really concerned that by the time the life cycle of the 4805 is up they'll stop working on the fix for the fix, and leave us with the choice of living with flashing or the original firmware

Martin Butler

I've already assumed that the flicker will not be fixed by the time we all upgrade - which is a shame.

I wonder if this will turn anyone away from Infocus...........

Geno, sad isn't it? I just don't see how InFocus can justify offering firmware with such a flaw.

sign me up as well

Signed.....Who cares if Infocus make us a new firmware....if it doesn't fix the flashing than I really can care less about it. It was nice of you to update us Bob but the point of this thread is to fix the flashing issue with the next firmware upgrade. You said this new firware does not so it is still a big failure on Infocus's part.

Please explain/describe flickering and flashing problem.
Thank you

Maybe that's why the 4805 has fell down to #3 on projector central's top 5 list and sinking like a rock...

BuffBakerGA

Projector Central, as has been mentioned and argued ad nauseum, is not a good source for info - they do not know what they are talking about!

Nonetheless, yes the firmware fix is a problem. But does it detract from its value? I don't think so.

Maybe that's why the 4805 has fell down to #3 on projector central's top 5 list and sinking like a rock...

It could also be that the 4805 has been out for a while and the competition is finally catching up. Not unrealistic that competitors would try to make their new products better than current released competitors products.

I let the bleeding edgers upgrade their firmware. If they bleed with the upgrade I hold off. Glad I am still at the original firmware on my 4805. What minor issues there are simply are not bothering me.

Having firmware upgrades available for download is part of a good faith effort on our part to help with issues that appear in the field after we begin production. I hope you understand that and take into consideration our position relative to the rest of the marketplace as many of our competitors do not offer this service. We strive to make it as easy as possible for end users to deal with any problems that come up.

Bob,

Thanks for everyone's hard work out there in Wilsonville. I know how nasty it can be when you're tracking down a tough bug. I sure hope you're able to fix it with the next firmware release.

Hi Bob-

Any chance there will be a firmware update with an even lower power mode (and slower fan speed)? I would like to be able to "simulate" the effect of an ND2 filter.

Any ETA on the new firmware?

Thanks again for popping your head in.

My 4805 shipped with v113 on it. I noticed the flickering pretty quickly. Can someone point me at the previous version of the firmware so that I can do my own taste test?

Take care

mrehrer - here you go:

http://www.infocus.com//service/software/downloads/4805v102.exe

Thanks Jeff!

What is the general consensus? Is there something in 113 that is valuable enough to put up with the flashing (assuming you see it)?

Take care

I rarely get any flashing since most of my DVD watching is over DVI. It shows up more over component at 480i. I also like the auto syncing in the new firmware, so I've kept it ever since it came out.

Hi mrehrer - the old firmware does not sync properly when switching from 480i to 1080i sources. This requires you to hit the Autoimage button on the remote to sync the picture. If you switch back and forth between a cable HD box and your DVD player, this can be a bit of a PITA. You eventually get used to it however, and believe me, it's much less annoying than the flashing. :)

The other chief disadvantage of the old firmware is that it lacks the letterbox mode when using DVI. This can be a big deal if you plan on using only a DVI connection with your DVD player, since it means that you'll be forced to watch non-anamorphic letterboxed DVDs pillarboxed in a 4:3 window. That makes the image mighty small!

Do you guys still keep the faith 'bout getting at least an upgrade before Xmas ?

ok, now you have 142 :)

Done !

done

Why not just set your cable\sat box to output 1080i or 720p at all times? My box has this option; it always send a 1080i signal whether I'm tuned to a hi-def channel or not.

Sounds like mbaxter has a suggested work-around for 102; for the 113 folks have you tried changing your sync threshold (I think that is the lable for the parameter). I do not have multiple timing sources at this point (mostly 480i via component) but I see the flashing frequently. Last night on a whim I changed the sync threshold to 100 and it _may_ have eliminated the flashing for me. Who knows what this does to the ability to sync to a new source (since I don't have a variety ) but it might be a good compromise to try.

I think I figured out why not to do this...

Was ruining a lovely Friday at the office when I got a call from home...long story shot the projector was not recognizing the DVD player input on power-up. I am guessing that the old autoimage trick would have worked but at the time I was not thinking about this change I made last night.

I will have to get to the bottom of this later.

I think I finally see the flashing that everyone is talking about. I'm not sure.
I have the 4805 flashed to the 1.13 firmware. I am using a Sony progressive scan dvd player to source the material to the 4805 via a component cable. During a certian concert (which is fairly dark) the upper 1/4 of the screen flashes. If I play the same video on a normal Sony 53" high def tv, I don't see the flashes/errors. I only seem to see the problems on concerts and not movies (from what I can tell) I do have Digital Video Essentials which seems like the default set up is pretty close (which is what I'm running except the ceiling mount option is being utilized). Is this a problem with the firmware, the configuration of the contrast, brightness, color, etc or ????

This is going out to the 91'ish Infocus 16:9 screen which is a re-labeled Da-Lite.

Thanks!

Updated first post with statistics. Need more signatures!

FIRST POST!

Hello Everyone. Just purchased a 4805 last week. Was wondering if anyone can tell me if this is firmware related:

On my advanced menu, I'm missing the Color Space, Video Standard and everything between Sync Threshold and White Peaking.

Can anyone lead me in the right direction? I don't want to risk contracting the flicker STD if I don't have to.

ARgh...last night I was watching a movie and was fooling with the gamma presets and settled on "CRT" as actually being the best for this movie - the colors were pleasing and the blacks were good - basically like it had been calibrated with the brightness down correctly. But with that lower level output the *flashing* was very apparent all the time and drove me crazy. I may have to downgrade the firmware today. I had to finally punch the gamma back up so it wasn't as noticeable.

Cmon infocus, let's get a fix!!

signed on!

geesh what would happen if Microsoft made a product that kept crashing or you had to reboot your system all the time..... ahh ok bad analogy.....

How is it possible that this issue has existed for a number of MONTHS and Infocus has not addressed this yet? Has anyone heard any word on a new firmware coming out any time soon?

Here is a generic thought that could go here or the MyHD thread or the Hauppauge PVR site or the Sigma Designs forum and probably a few other places that I'm not familiar with. Drivers for hardware devices built on other people's chipsets must be developed with the help of the chip's engineers and they have two issues that limit that help.

One: They don't want to disseminate information that their competitors could use to develop alternative products. (Not all info is protected with copyrights and patents) They may not be forthcoming with needed help as a result. This paranoia also makes field repair of most digital Consumer Electronic Products impossible too.

Two: They don't want to waste time on an "obsolete" product. They are busy developing new products and they prefer set-top-boxes where they can hide the interfaces from prying eyes.

Friend Bob, thank you for their support and to be pending of our restlessness. I hope they take into account my projector reports the same problem (momentary flashes ), however I have installed the version 1.02, so I don't believe that it is software problem. We hope they can get to the brevity a solution to the outlined problem.

Thank

Enrico Castagnetti (Venezuela)

Added my signature.

Just added mine.

Any status on the next firmware?

Thanks,

I'm going to unstick this. The unfortunate truth seems to be that we're not getting any more answers from Infocus.

Count me in.

All,

Pending such solution, we have looked at every option available to us including writing an enhanced version of software based on the original software release, but those software libraries are incompatible with the enhanced functionality of the new releases.

We will continue to work on this issue and will try to provide a solution quickly.

InFocus does appreciate the contributions of this forum, and we try to monitor it on a regular basis. Although we don't post very often, we do listen to you.


Wouldn't be possible at least to check if only adding to 1.02 the Letterbox over DVI would trigger the flicker issue ? Personnaly, it's the only important fix to 1.02 that I wish I could have...

any current links to the old 1.02 firmware the one provided only shows the 1.1.3 version

I got a "page not found error" has this already closed? Anyway I will try again later.

Signed the petition.

What I do not get is, if it were not a problem in firmware 1.02 (I never tried this firmware) and it appears in firmware 1.13 then it seems like it must be a software problem. If it is a software problem then most likely there is an "easy" fix...

From the Infocus Engineers post I interpreted it as it was a very difficult problem to solve... ???

There is a NEW 4805 Firmware 1.2.1 dated Sept 20 2005!

Here is the link. (http://www.infocus.com/service/sp4805/software.asp?site_lang=1&site_region=1&)

Thx SuperGoop!

Have you downloaded it yet?

If so is everything working like it sopose too?

Unfortunately it has not proven to be easy to fix. Yes, it is a software problem but the software is very complicated in this area. Basically what is happening is that the microprocessor is hiccuping occasionally and losing track of the color wheel position momentarily. This forces a soft reset and a resulting flash on the screen.

We have had teams all over the world working on getting this issue fixed. The new firmware version (1.2.1) on our web site does not fix this issue since it was completed before a fix was found.

All that being said, we now have a version of software undergoing internal validation that does appear to fix the issue. I personally tested it this morning and it seems to work. I do not know when it will be available for downloading, but we're one step closer to eliminating this issue altogether.

Thanks Bob. Glad to see you guys are still addressing this little beast while working on your new stuff ;)

Hi Bob:

This is slightly off topic, but do you know if the redesigned 4805 (Triton X-10) will have sealed optics?

I hope this gets released. I cannot calibrate the component inputs for lack of adjustments in the original firmware.

I hope you understand that and take into consideration our position relative to the rest of the marketplace as many of our competitors do not offer this service.At some point I think you were asking about desireable new features; perhaps you could fold these ideas into a firmware upgrade for existing as well as new product:

User-defineable "overscan" at top of pix to eliminate Closed Caption data, etc.

Discrete remote codes for:
OnOffPresets 1|2|3

Props to Bob for keeping us updated. I think it's great he keeps involved....very brave of him

Now, if we can just get the fan to completely shut off when I turn the projector off.......darn annoying thing

Bob,

First and foremost thanks for keeping us updated and letting us know Infocus is still working on resolving this issue.

I can see now how this issue might be difficult to solve. Out of curiosity, what sort of hiccup is it? Processor hangs? Some other fix takes to much cpu time and the processor looses track of wheel?

Again thank you for taking time to respond to this thread. I look forward to receiving the fix.

Thank for the update... awaiting your final confirmation...

... so we can ask you for other tweaks ;)

Hey this is good news. Thanks to BOB for keeping us updated. Now let's all just hope that the beta version BOB has been testing becomes available soon! :D

So, If I upgrade from 1.02 to 1.21 I will most likely get this light flicker, or does it only happen when going from 1.02 to 1.13?

Not everyone gets the flicker.

I have a flicker when I am running my 4805 on "Low Light". I have about 360 hours on the bulb and it just started about a month ago - maybe 20 - 30 hours or so.

It is fine when I run it on full power but the fan is way too noisy.

I have tried running it for several hours at a time on high power to see if it will "fix" it but when I go back to low power it still flickers.

I am running the original 1.02 firmware. Will upgrading the firmware help with the flicker?

I have seen some other issues with firmware upgrades mentioned, is it worth it or would it be better to wait for the next release?

Bob, any updates?

Thanks,

In your case Jimmy, it's prolly the bulb. The 1.02 firmware was OK. I'd try to get it replaced before it hit the 500 hour warranty limit.

Bump...

Bob?

This is a real joke.....

It kinda feels that way...

Bob? Hows it lookin with that fix you had going 2 months ago?

Bump I guess, I get the flicker

The fix is still in process. We have a version of firmware in our labs undergoing validation that I believe completely fixes the issue, but we have to go through the dilligence of fully testing everything to make sure. I do not have a schedule for release to the public, but if this version passes all of our tests then it should not be too long from now. That's all I can say right now.

Good news indeed. :)

I do not have a schedule for release to the public, but if this version passes all of our tests then it should not be too long from now. That's all I can say right now.

That's what I'm talkin' about!!! You go Bob!!! :D

Bob thx for the update!

I was just logging in to post my DISGUST about the whole situation, and what do you know? Apparently we are very close to seeing a fix. I'll give INFOCUS another chance, and wait a little longer to see if the problem is resolved once and for all, with the impending update/fix.

Frankly, if I don't see a solution within the next 3 months, I know for sure my next Projector will *not* be an InFocus! That's probably a $3500 sale lost right there. Peanuts for InFocus, sure...

A somewhat difficult and frustating situation to be sure, if you have the flickering problem.

However, although Infocus is not putting this out as quickly as one would hope, they are still pursuing the issue. Also, I have certainly heard a number of worse horror stories by manufacturers in other fields.

Also, even if someone upgrades prior to the fix being issued, the fact that a fix is in the works should help resale values somewhat.

I have a flicker when I am running my 4805 on "Low Light". I have about 360 hours on the bulb and it just started about a month ago - maybe 20 - 30 hours or so.

It is fine when I run it on full power but the fan is way too noisy.

I have tried running it for several hours at a time on high power to see if it will "fix" it but when I go back to low power it still flickers.

I am running the original 1.02 firmware. Will upgrading the firmware help with the flicker?

I have seen some other issues with firmware upgrades mentioned, is it worth it or would it be better to wait for the next release?

It's not the bulb. I've has three 4805's with this exact problem. My first one I returned to the dealer. My second one I sent in for repair and it had some kind of problem with a board inside, the fix was taking so long they just sent me a replacement. Now my replacement is now doing it, I've sent it in for repair so I will have to see what they do this time. But it's not a bulb problem, it's something else.

I do not have a schedule for release to the public, but if this version passes all of our tests then it should not be too long from now.How 'bout a 'beta' release? Or even an 'alpha' release. Just for the freaks on this thread. They would surely give their eye-teeth to test it for you! If it doesn't work, they can always reload the old firmwware!

That would put you on their Christmas card list for sure!! ;)

I would have to agree as well. I have only 180 hours on mine and get the flicker. It's not noticeable when the picture fills the screen, however on some widescreen material you really can see it flicker on the black parts of the screen. It really drove me nuts one night watching a movie. I have a spare bulb I can try but I'm thinking it's not the bulb.

Usually I don't notice the flicker unless I put up a blank white screen. But occasionally it is very noticable in actual video, that's why I decided to send it in. I will see what they say is wrong in a few days, last time they replaced some board but I didn't actually get to see if it fixed it because like I said they ended up sending me a referb replacement. It seems like some type of power instability or something, when the bulb is getting more power there is no problem, just in low power mode. Perhaps Bob could let us know more, since I've had three units develop this problem, it's got to be pretty common.

<------------ Willing beta tester!

I have less that 10 hours on mine and just got it about a week ago and I have this damn flicker. When is this going to be fixed. If it isn't before my 30 return is up this thing is going back.

Just downgrade your firmware to the 1.02. I have it and have never ever seen a flicker. None of the features in the newer firmware are that great that you can't live without them. The only real feature i know of is that the 4805 will sync automatically when changing to different sources, instead of having to hit the autosync button on the remote.

Downgrading your firmware will fix the problem for the time being, until the new firmware comes out that we all can upgrade to.

Bob Williams et All,

Did anybody have this problem when changed the firmware from 1.1.3 to 1.2.1? I made the firmware update this weekend (1.1.3 to 1.2.1). In this occasion I was making some tests using the computer through VGA connection. I am suspecting that had some change in the way that 4805 recognized the video signal in the native mode (at 800x600 resolution). Before the update, the image was cropped at the top and bottom (600 to 480 pixels) and I had two black side bars (800 to 854). After the update, the native mode works similar to 4:3 mode, shrinking the image to fit a 640x480 pixels rectangle. Does it make sense?I wrote this message in october at the "Highlander" 4805 topic that is now closed.

Thank you.

Filipe Rangel.

A belated Merry Christmas & Happy New Year!!!

Any update for us on the firmware update??? ;) :D

Bob, is there a status update on the fix, please?

Also would like to know about the firmware... seems early Dec you said it was almost ready, can we expect it any time soon?

Does the "flicker" problem exist on DVI? I have never seen it, regardless of firmware version, but I only use the a DVI input.

Also would like to know about the firmware... seems early Dec you said it was almost ready, can we expect it any time soon?
I sure hope so. Our validation resources have been strained lately due to the pending introduction of a new product line, but that's a lousy excuse (in my humble opinion) for not providing a solution yet.

All I can ask is to be patient. It's coming.

Hi Bob - does the upcoming firmware release contain any other improvements or modifications, or does it just fix the flashing bug.

Also, if you feel like giving an explanation of what was causing the issue and why it only affected dark scenes, only affected certain DVD players, certain DVDs, etc - I'm sure a lot of us would be interested to know.

Also, just to squeeze in another question - I know the later versions of the software add letterbox support for DVI input, but is that also true for HDMI input via the M1? I assume so, but I'll be going HDMI soon and I need the letterbox mode for my anamorphic lens so I just wanted to double check.

Thanks much!

Maybe you could "accidentally" attach it to one of your posts on the forum? Just for a little bit?

I tell you what it better be soon (within a few days) or this unit is being returned to Best Buy! :rolleyes: Other than this strobing while watching 24 I love the picture. :)

Hi,

Is there anyway that there would be NO firmware upgrade, since the new line of projectors are out, and obviously the attention is on them? Would infocus do that to us?

Bob has mentioned last week in the new Infocus projector thread that the firmware will be released very soon.

It's supposed to be fairly soon but definately coming.

Return it?? Just re-flash it with the original firmware while you wait, silly.

How LONG have you been waiting :rolleyes: I wouldnt mind putting a bandaid on a new wound... but not if it has been around since 04 :eek: My 30 days for a return are up later this month, hopefully the long awaited fix for my strobing will be here by then:)

I'm not waiting at all. I reflashed with the 1st version firmware as soon as I found out the bug in the later firmware was being hard to find. I might not even re-flash with the new stuff when it comes out. The original firmware was fine. Reflash it and forget it for now.

-W

Hi,

Is there anything negative to flashing with the earlier firmware? Does it void the warranty in any way?

Thanks!

No real downside, you need to hit the auto-image button once in a while when changing sources as it does not auto-sync as well. But once you hit the button ONCE, it's fine.
No it does not void the warranty.

-W

OK I flashed to the original firmware and no more flicker, but my picture looked different... somewhat blurry and not as sharp? :mad: I flashed back to the new firmware and the picture is good again? :rolleyes:

Hi Piranha - I've run both the 1.02 and 1.13 versions of the firmware and there was no difference in PQ that I could see (outside of lack of flicker in the 1.02 rev of course). Tons of people have either updated their firmware to the new version, or reverted to the old, but yours is the first post I've seen that claims a PQ difference between versions.

Reloading the firmware causes the picture settings to revert to their default - could that be your problem? Did you have sharpness cranked on the new version?

No tweaking just straight out of the box calibration... I just flashed it again and I can definately tell a difference... I'm just very picky I guess. I wonder if the newer firmware accepts a 1080i signal better?

Are the "defaults" on both firmwares the same???

I'd raise this question over on the Official 4805 thread now.. THIS is news you're getting into. :)

Update: The new firmware has passed all of our internal testing. It should be posted on our web site shortly. The new version number is 1.3.2 and it fixes the flashing issue.

# Fix for random image flash seen when playing DVD movies
# YUV input improvement
# Improved operation when Macrovision is available (analog inputs)
# 480i/576i about menu reporting corrected
# 480i/576i overscan corrected
# Save mode now restores phase setting

Great news. Maybe Bob could expand on some of these other changes, beyond the flash fix, especially the YUV input improvement.

Can someone please tell me if I need to flash each subsequent firmware release in order to get to v1.3.2 ?
i.e I am running v1.2 - Do I need to flash v1.13, v1.2.1 & v1.3.2 to get all the reported corrections (fixes)?
Thanks,
Sammy

Sammy: no you don't need to perform in sequence...

Excellent! I guess the Flash is erased prior to each firmware upgrade so the latest firmware release should contain all the fixes.
Thanks,
Sammy

Wow! that's great. Thanks for keeping us posted Bob. Now... is this for PC's only, or can I download a version for my Mac?

Cool... will have to try it tomorrow. Don't like that you have to register to download though

Does anyone know if applying this (or any) firmware will reset all custom settings on the PJ? Do we need to go in to the menues prior to flashing and taking note of all our settings prior to flashing?

Might be too late for me, as I already flashed... not sure if settings went back to default.

I think it resets it. I just updated the firmware and I had to set my pj to ceiling mode again. Might want to write down your numbers first.

any reason to upgrade if 1.2.1 seems to be working? Only get very ocasional pulse in dark scenes. Running components now, but want to do a pixel mapped D1 or D2.

That was easy (the toughest thing was finding my M1/USB cable). Although I had to reset the ceiling checkbox, it otherwise didn't change my settings at all. And it seems quieter in low power mode. :) I've avoided the previous upgrades because of the flashing issue, and just put up with having to hit the auto image button after changing sources (I won't miss that at all). :mad: If I see the flashing, I'll let everyone know right away.

That was easy (the toughest thing was finding my M1/USB cable).
I have never updated the firmware before. Do I understand correctly that I need to go out and buy this "M1/USB" cable? I've never heard of this kind of cable before. What should I look for, and where might I find one?

Thanks.

-Dan

Hi dagware - the cable comes with the 4805. Look in your box.

Excuse me for being a little scheptical but can anyone report on the performance of the new firmware before I take the plung.....

Hi dagware - the cable comes with the 4805. Look in your box.

Yep, it comes with the projector. I just couldn't remember where my cable was.

Don't know what the flashing looks like, but I just watched Sin City (I assume that's a good test) and noticed nothing unusual at all.

Thanks to Bob and InFocus for staying on the case. ;)

Try "Collateral". That movie was THE worst when it come to triggering the bug. If that's clean, things are looking good. :)

Of course, the thing with this bug was that it didn't happen with all DVD players and was not always repeatable with the same movie!

Can I get the new firmware for my mac, or is that not possible?

I don't have that one handy. Does anybody have a link (other than trolling through the 4805 threads) that identifies the problematic movies and players? I'm more than willing to experiment this weekend. :confused:

Hi Spongeworthy - I believe "Ray" was another problem film. Matter of fact, the joke was that Jamie Foxx was causing the bug!

I have confidence Bob Williams & company have fixed this once and for all. I hope to load the new firmware over the weekend and check out some discs that caused me problems when running v1.13.

Hey, where's Schenectady? That sounds vaguely familiar! :D

Hey, where's Schenectady? That sounds vaguely familiar! :DSchenectady is in upstate New York, about 10 miles northwest of Albany. Less than 2 hours from a lot of superb skiing.

Has anyone ever experienced the flashing with the opening dark scene in Master and Commander?

Hi dagware - the cable comes with the 4805. Look in your box.
Thanks. I was able to find the cable and install the updated flash. It works great, however I forgot to save my settings, and they all got wiped out. But that's not really a big deal.

Anyone know where I can download the firmware upgrade file other than the Infocus website?

I cannot find any document with my serial number, and I really don't want to remove the PJ from my mount just to get it from the underside.

Thanks for any help.

Just upgraded, I'm using 480p over component, calibrating with avia the contrast and brightness settings are now both at 50, before the upgrade calibrated contrast was 36 and brightness 53

You can download it here:

Thank you! There are very kind and generous people here, just like over on the Tivo forum.

:)

Bob stayed true to his word! Now I just have to dig out that cable from storage.....

I upgraded mine and have watched two movies so far and no flashes. My contrast and brightness settings stayed the same. Works great!

I cannot find any document with my serial number, and I really don't want to remove the PJ from my mount just to get it from the underside.I suggest that you write your serial number inside the front cover of your SP4805 manual; you can also track total projector time by recording when you change lamps and reset the counter.

So does this also fix the flicker problem in "Low Power" mode?

I suggest that you write your serial number inside the front cover of your SP4805 manualGreat idea. I've done this before with other pieces of equpment. I don't know why I didn't do it with the SP4805 manual.

If you kept it, the serial number is on the box the projector came in.

I suggest that you write your serial number inside the front cover of your SP4805 manual;
If I had the serial number handy to write it in my manual, then I wouldn't have posted here in the first place! :p

That was the first thing I thought of. I'd already cut it out to mail in for the free screen (which I never used).

Fellows,# Fix for random image flash seen when playing DVD moviesGreat news!!! :)# 480i/576i overscan correctedI saw that my SP4805 presents a bigger black edge in 480i than in 480p images. Is this what this update item relates with?

i checked it out and the upgraded firmware works great no issues that i can see, thanx bob......

flashed my refurb'd 4805 today...was running 1.13 until now.

flash went off without a hook, and right away i noticed the fan noise was DRASTICALLY reduced (along with airflow). we'll see if this holds true when i put the projector back in service later tonight.

in any case, no problems so far.

Piranha ,
I have the same problem, the picture quality is more blurry on 132 than on 102. on 102 the SHarpness is a lot better... i like 102 PQ a lot more.

So for now i´m going to stay with 102.

I wish to know why some people are having this "blury image" thing......

I flashed the latest firmware and I think it is a step backward in terms in PQ. Fan noise has been reduced significantly. I will give it another week and see. I think I am going to go back the the original firmware.

Bob,

Can you chime in and tell us if there were any changes in the latest firmware that could have affected Picture Quality / Sharpness of the projector?

FYI, links to all three firmware versions...

1.02 - http://www.infocus.com//service/software/downloads/4805v102.exe
1.13 - http://www.infocus.com//service/software/downloads/4805v113.exe
1.32 - http://www.infocus.com//service/software/downloads/4805v132.exe

suprised nobody else has posted these. hopefully they help somebody.

FYI, i noticed quite a few more artifacts on 1.32 than i did on 1.13. i'm thinking of going all the way back to 1.02 as that one seems to be popular for PQ.

I'm having trouble registering my 4805. I can't get the serialnumber to work.

Should I just download the update from the unofficial web page, or is that a bit risky?

FYI, links to all three firmware versions...You missed one: v1.21

I'm having trouble registering my 4805. I can't get the serialnumber to work.Did you actually ever register the projector or are you just trying to use the SN to download the firmware??

I believe the projector has to be properly registered with InFocus for warranty and support (including firmware) purposes.

Call their customer support dept in the morning and register it "live" with them; if there is a problem, they will let you know.

Did you purchase your unit from an "authorized" dealer??

People seem to have forgotten that 15,500 Infocus projectors (~$20M) were stolen over a year ago and sold through illicit channels. There is no warranty on those units for obvious reasons.

I know of what I speak! My first SP4805 was "hot" - stolen from the Chicago warehouse. I discovered this when I tried to register the unit.

It took police involvement including the FBI, the RCMP and, oddly, US Homeland Security for me to get my money back from the dealer.

I was a little smarter when I bought my next 16 SP4805 projectors - I have two - the rest were for family and friends. ;)

cavu: I've never registered my 4805, and I bought it used. I live in Europe, so I don't think it's stolen.

I downloaded the latest firmware from one of the links above, and I've updated my 4805. The biggest, and finest improvement, is that I don't have to press the "Auto Image" button when I switch from Xbox 360 (720p) to DVD (576i).

Someone mentioned an increase of dithering (artifacts), and I believe I can see it too.

Anyway, I'll use the newest firmware for now, but I'll change back to the 1.0.2 firmware if the PQ is affected in a negative way.

cavu: Wow, 16 x 4805!

Are you serious?

If you bought 14 projectors for your ralatives, you must be a pretty wealthy person, and a very caring and nice person.

Hi-

What is the concensus on this firmware? Is it 'the one". I've been sitting with the original firmware and just using a single component run (so I am not exposed to the flicker issue). I typically keep all of my hardware on the latest firmware, but have been sitting in the "if it ain't broke don't fix it" camp.

Is this the one to upgrade to?

Thanks,

I wouldn't upgrade if you don't have any issues with the current old firmware that you are using. The main fix in the newer updates not available in the original firmware is the automatic resyncing of video modes when switching between 480i to 720p/1080i and vice verse. With the old firmware, you would need to press the auto-image button to fix the distorted picture that you would get where the new firmwares would do it automatically.

I hear ya... I am hoping to get an HD Dish box hooked up to the PJ in the next few months, so I'll probably run into that issue soon. I'll sit on it another few weeks.

ttt... I'm also waiting for the decision on whether to upgrade the firmware or not...

Experts?

Has anyone heard anything from Infocus regarding the decrease in fan noise? I can't imagine that it was intentional since it isn't mentioned as one of the firmware changes on their website. I would love to decrease the fan noise, but, obviously, not at the cost of bulb life.

Has anyone heard anything from Infocus regarding the decrease in fan noise? Unfortuantely, the decreased fan noise I noticed after flashing the new firmware was not permanent. It soon reverted to its familiar state - noisy as ever :( .

Same here. It seems like the fan speed controller gets reset when you flash it, but then adjusts itself back to the loud fan speed levels.

That might be good..... we don't want the fans under-cooling the bulbs.

I guess no news is good news... normally this or the main thread would be flooded by now.

Thanks,

...updates?

I guess no news is good news... normally this or the main thread would be flooded by now.

Thanks,No problems. My settings looked the same after the upgrade, but I recalibrated anyway because I thought DVD's looked a little dim. While calibrating, I noticed that my prefererrd setting of "sharper" had defaulted to standard. This might explain somwehat why some thought the picture was softer or blurry after the upgrade. Not softer or blurry anymore.

Cool... I have a buddy with the old firmware that could use a nice, auto-switch when the resolution changes... I'll try it on his first ;)

Well... I upgraded mine first. It was very easy to do. Only one movie, but so far so good. I played with 480i/480p on my rp-56 to test the re-sync. It works.

I sent my buddy the firmware so he can do his PJ.

Hi-

Again... the upgrade to 1.3.2 is done.
I was watching The Incredibles the other night. Prior to playing the movie, while the DVD was on the menu, I hit the 480p button on my Panny RP-56 DVD player to test the re-sync. I then watched the movie. During the credits at the end of the movie, the screen went blank about 3 different times, and the PJ showed the "Video 2, 480i" message box.

Coincidence? This is the first time I've watched the movie through the credits, so I do not have anything to base this off of. Any thoughts? While I am asking, what does that sync threshold option do?

Thanks,

Where you watching the movie at 480i or 480p? Sync threshold adjusts the sensitivity of the analog connections. Sometimes when there's a flash of white or sudden change of color, the 4805 will think that it lost the signal and try to resync. Adjusting the sync threshold would adjusts this. I'd try to replicate the problem and begin messing with the sycn threshold.

Hi-

I was watching at 480i via component. There was no flash, per se, but the credits were basically all black from a mixed-color scene. What you said makes sense. I wonder if the mostly black of the credits rolling made it think there was no signal... By the way, it did not do a "searching for signal" message box; only a "Video 2, 480i" message box.

Which way should I move the sync threshold (i.e. does increasing it or decreasing it make it more stable and less prone to try to resync)?

I am still running the original firmware. I have a iScan HD+ video processor that I run both HDTV and DVD to. The HDTV box is connected to the iScan via DVI @ 1080i and the DVD play via component @ 480i. From the iScan to the PJ is DVI - M1 @ 854X480P in native mode. I have no problems with switching channels from HD to SD. My question is will the new firmware buy me anything?

I see no reason for you to upgrade. Your scaler is dealing with the switching from HD to SD. All the 4805 knows is its receiving a constant signal at 854x480 from your scaler, with your scaler controlling the various resolutions and then sending them out to the 4805.

I turned the threshold up to an arbitrary 63 and watched King Kong last night. The issue of the screen going black did not come up. I am not claiming victory, in part because I still do not know if I increased or decreased the the sync stability by turning it higher. Any thoughts?

Btw, in the big thread there is another guy with a similar issue where the screen is black (not blue) and the PJ still shows the proper resolution that you are inputting. I do not know which firware that person has. FYI...

Isn't there a setting on the 4805 for the background color? If memory serves, the choices are black and blue. This would explain the color differences.

Yes...Black, Blue & White.

Thanks for the clarification.

Oh, and regarding your tag line "So, you measure your TV in inches eh? That's cute. Mine...over 7.5 FEET!!!" -- mine's over 9 feet. :D Actually, I've quoted a variation of your tag line to quite a few people. I love seeing the looks on their faces!

I could actually go bigger...zero zoom/total light control, but I wanted to keep it at the pj's sweetspot.

Oh, and those reactions you get when you tell people the size of your tv :eek: IS priceless! :D

Hi-

To clarify...
This is a different issue. My background color is indeed set to blue (the default). My issue is (was) during the credits on The Incredibles several times the screen went black. Eventually the box with the resolution and input would show up and the picture would come back. The box did not say "searching for source" or whatever it says when it is scanning for inputs.

JaPhule thought I might need to increase the synch threshold. I bumped it up to 63 and watched King Kong with no issues. I've only watched 2 movies since I upgraded the firmware, so I don't know if this is solved or not. While the issue was going on with The Incredibles, I happened to decrease the sync threshold, which did not solve the issue.

Still, I don't know if making the number higher makes it more sensitive (and therefore less stable) to frequency/resolution changes or less sensitive (and therefore more stable).

I think you're headed in the right direction. Keep playing with the sync thresh, and try turning off your AUTO SOURCE if it's on. Just a thought.

I'm sure it's something to do with sync threshhold and it seems to vary from device to device. One time I was messing with it (though I don't remember if it was on the high end or low end), and it was too sensitive and the 4805 just kept resyncing.

Both good comments... I will play a bit more this weekend.

...an update

First, I went into the menu and the 'blank screen" setting had been turned from blue to black (I never did that and I prefer blue). That kind of changes my description of what happened above. Regardless, I believe changing the sync threshold fixed my problem.

On the other hand, I have not been able to tweak the picture to look as nice as it did with the original firmware. The main thing is there seems to be more crawlies or something. It's almost like the source (dvd player) is putting out a dirty picture. Turning down sharpness does nothing. I did not do any fancy tweaks, other than turning down white peaking to zero. I believe my gamma is film (and I have played with video).

Has anyone had a similar experience with the PQ degrading?

Anyway, I am probably going to flash back to the original FW.

Someone mentioned that their default keystone setting (at 50) was giving them some artifacts, going down a notch to 49 actually made the picture clearer for them, maybe you should try messing with the keystone b/c the default setting may be off for you.

Thanks Ja Phule... I'll give it a shot. Worst case, I'll flash it back.

Well... I played with the keystone last night... no noticable difference. This latest firmware seems to carry more noise with it. I'll let you know what happens after I flash it back. For all I know my eyes became unnaturally perfect. ;-)


...fwiw...

Well... I flashed the firmware back to 1.02 last night. There is a night and day difference, imo.

My issue was that with 1.32 there was an increase in noise and artifacts. There were more crawlies than with 1.02, and there was false contouring/clay faces, which I had never experienced until the new firmware. It's almost like they took a bit from the PQ to make room on the flash-rom for other items. Playing with the keystone (as suggested above) did not help.

Now that I am back to 1.02 there is a very noticable improvement in PQ.

...on the other hand, now my contrast and brightness settings seem to be changing when I put them into memory. For example, I can set contrast to 57, save the setting in #1, hit setting #2, then #1 again and contrast will be 55. I haven't done a hard start yet (in other words, I flashed and set the settings), so that may help... still, if you've heard of this and know what's up, feel free to chime in.

Hope this helps,

...one last comment. I watched The Incredbles again the other day. If you recall that was the DVD where I experienced the screen going black a few times during the credits (playing with Sync Threshold may have fixed it). With the original firmware there were no issues.

FWIW

hi all,

i just gotten myself a 4805 with fw 1.2.1 out of the box.
i hooked it up via component with a cheapo CyberHome dvd player.
but i can't seems to see the flashing that everyone is seeing.

can anyone elaborate wat exactly is this flashing?
is it something as bright and as fast like a lighting in the sky?
and does it happens always at a particular sence?
how frequent is this flashing?

i watched LOTR:Return of the King with a lot of dark scenes,
but can't seems to see the flashing.

but i do notice that there is a bit of noise in the image.
i am wondering is it becos of the cheaper dvd player that i am using?
or do anyone experience degrade of PQ in terms of noise when they upgrade to 1.2.1
I wonder if the noise will go away when i downgrade to the original fw


thanks for reading. :)
hope to see some replies. thanks!

I suffered from the 4805's flicker problem (my 4805 shipped with 1.13), so I recently upgraded to 1.3.2. After reading some of the posts in this thread, I became convinced that the PQ was suffering, so I reverted to 1.0.2 from the upgrade. Unfortunately, since I'm just running a single source (Marantz DV9500) into the 4805 via hdmi, the lack of letterbox support on 1.0.2 made it a no-go.

I've since switched back to 1.3.2, and while I think I see some differences in the PQ, I'm really not certain. I was just hoping that some other people might chime to relate their experiences with the 4805 and various firmwares.

Well, I can tell you that I've got 1.3.2 and after watching the USA world cup game in HD.... I'll be switching back to I believe 1.2.1.... whatever one is just before 1.3.2

I compared the IN72 to my 4805 and there were crawlies up at the top where it said "World Cup" on my 4805 that wasn't on the IN72. Fact is I don't care what firmware I go to as long as it doesn't have these "crawlies". I haven't noticed the flicker issue ever, but this you can see.

Hi!

I got another problem with my 4805. When I am looking at movies using my dvdplayer with dvi connection to my 4805 all the black parts of the picture gets very filled with noise. I don't have this problem when I am using component cable . Has anyone the same problem as I? The picture is very good except of the black parts of the picture...

Either you need to adjust the RGB menus for Video DVI setting - or you have bad digital cables. You can help out your digital cables by sending a lower bandwidth 480P - there is not advantage in upconverted DVD.

Bob set the cropping values on the IN72 to eliminate those "crawlies" but you will be missing pix info on the other three sides of the screen as well when you engage it.

That's not what I'm talking about..... But thanks for the info. I'm talking about the actual lettering that ESPNHD was putting over the live action... items like the score and time and who was playing. You would see a defined letter and then on top of it a 1x1 white pixel would "crawl" across the top of the letter and it did this on every letter. I tried every firmware and it made no difference... it still did it. Maybe it is my DCT-6412 III as there is a different DCT-6412 III hooked up to the IN72. I didn't try the other box on my 4805 because the game wasn't recorded on that DVR. But when the game was live both were on and on the same channel... the IN72 had no crawlies and the 4805 did. I think it could be a scaling issue.

I was just hoping that some other people might chime to relate their experiences with the 4805 and various firmwares.I flashed the new firmware right after it came out. I was so happy not having to hit the auto-image button whenver I changed sources that I didn't get too worked up about what seemed to be a softer-focus picture, tho' I did find myself trying to adjust the focus every day. I sent it back 3 months ago for a different problem, and InFocus reported that, among other things, they upgraded the firmware (that I already had flashed). Since I got it back, the projector looks better than ever -- brighter, sharper, almost better than brand new. What to deduce from this? Don't know why, but flashing the firmware on your own doesn't bring about the same result.
