Optoma HD81-LV Discussion/Reviews - Page 11

post #301 of 493
Does anybody know where I can get an LV? I have seen the LV online at prices between $3800 and $5500 but this substantial difference in pricing has prevented me from pulling the trigger thus far. Also, I've noticed that some of the LV's I was looking at online may have been refurbished and naturally I want a brand new LV that has it's original 3-year warranty.

I'm getting my sound system, screen and other components delivered on March 8th and have yet to purchase this or any other PJ for reasons stated above.

Jeff Reagan, I have spoken to you quite a bit about the LV and wonder if you sir could help me find the best price for a *new LV.

Joe,

Agreed, I'm so relieved that my LV has been golden since August. I've got
around 500 hours now and only a couple of unplanned shutdowns.

Art,

Your bulb experiences are a concern. I think we should expect and demand bulbs that last close to 2000 hours, at $500 a pop, substantially less is ridiculous.

I now have three HD DVD players, XA2, A3 and A35. Neither the XA2 or A35
do the 24p handshake with the LV, as you know. If only two HDM players, both Blu Ray, are the only models that do 24p with the LV, Optoma should offer a firmware update.

Thank you for continuing to bring this up to Optoma service. Might I suggest
that we all contact David Hwang at Optoma, the HD8x series product manager about the lack of 24p handshake?

Hi again my friends. Today I spent an hour comiserarating over HDMI issues with a Comcast tech who was extremely knowledgeable and eager to learn. I had asked for replacement of my 3416 HD DVR box with a box with newer firmware. HDMI handshke issues have been driving me crazy. He had someone go through their inventory but fund no newer software in any 3416's, the latest and greates HD DVR cable boxes out there. I know there is newer software. They don't ave any boxes with it. I refuse to go to componebnt. Anyway in case you are having HDMI issues with our LV, my FW is from 4/27/2007. Problem iss the HJD DVR goes into diagnostic mode every so often when it is clearing HDMI permissions with our LV. It then changes resolutions and may even provide no picture to our LV. To get it working requires an unplug/replug of the 3416 and a complete setup. HATE HDMI!!!! Thought this might be helpful.

Art,

If you hate HDMI and refuse to go to component. Does that mean you hate component more? Do you really think the quality is that much better with HDMI?

I still have not gone hdmi with the exception of my htPC which is DVI-HDMI and have never had a single issue.

Joe,

There is no doubt in my mind, HDMI and DVI provide better transfer of video material than does component (YPrPb) or composite video. The resulting picture is sharper with more deply saturated colors and accurate hue. I say this without reservation.

Thanks Art. I am going to try hdmi direct form my cable receiver tonight. I will report back.

I tried watching a non-anamorphic widescreen DVD and couldn't get it to fill the screen. I tried using both my A30 HD-DVD player and my PS3. Both are connected using HDMI. I couldn't get the projector to treat it as widescreen. The projector treated it as 4x3 so it left black bars on the sides. Then the DVD itself had black bars on the top and bottom. I ended up with a small image and black bars on all four sides. When I select letterbox mode on the projector, it stretches the image vertically, but it won't stretch it horizontally so I still have the bars on the sides and a distorted image.

Is this because HDMI is telling the projector that it is a 4x3 image and the projector won't override that?

I tried changing the settings for display type on the A30. I tried 4x3, 16x9 and 4x3 letterboxed. I got the same results with each.

Has anyone been able to get a non-anamorphic widescreen DVD to fill the screen when using HDMI to connect the player to the projector?

Incidentally, I set the A30 to 1080p and now I have the same problem with it that I was having with the PS3 (which is also set for 1080p). When I first select it, the projector keeps doing continual resyncs with it. I get an image, then a black screen with a "no signal" message. Then it resynchronizes and I get a picture, only to have it go blank again. After a few minutes, or if I switch inputs a few times, it finally settles down. It looks like it must be an issue with 1080p input.

Thanks!

Joe,

I do think it's an HDMI issue. The handshake is telling the LV to stay in 4:3 and
that is all the players will output for the same reason. When I have a 4:3 source that has a 1:78:1 letterboxed within, I go to LBX and bring in my anamorphic lens, which gets me to a 16:9 image.

Have you tried using component output?

I have not had any handshake issues with 1080/60p with an A35 or XA2, but
neither will do 1080/24p due to HDMI EDID issues.
post #309 of 493
Joe,

Jeff covered it well but let me just add what I do on those rare occasions when I try to play an older non anmorphic 1:78 in a 4x3 window. I send the video output through my LG LST-341A HD DVR. This unit has a zoom mode that allows me to fill the screen. The LG then outputs via DVI/HMI to the VXP. Works well.

FWIW, I received my second replacement bulb from Optoma yesterday. I have now replaced the bulb twice on the LV.
post #310 of 493
Thanks Jeff and Art!

I was afraid it was something like that. Darn, I was hoping you'd tell me it was some simple setting I had missed.

I've been reluctant to go back to component since I use the one HDMI cable for audio and video. I'll have to figure out what I need to change to get audio without HDMI.

Art, that is scary about the short bulb life you have experienced with the LV! Lamps that expensive should certainly last longer than yours have.

Joe
post #311 of 493
Joe,

My wife agrees with you completely. We are now out of the 1 year warranty period for bulb replacement. At $500.00 every 3 months, I could probably buy a new projector andbe money ahead within a couple years. This has not been and continues to not be a good experience. Were it not for Warren Pierce, I would be taking action.
post #312 of 493
I'm looking for some information that has been mentioned on these forums about the pinout for the RS-232 serial cables for the HD80 and 81. I recently purchased a 60 foot db9ff cable, and it doesn't work, so I am assuming the pinout is not correct and was wondering if there was a solution to this.
post #313 of 493
UAF,

The cable provided by Optoma is a null modem cable. If you purchased a straight serial cable, you should either mate it to the supplied cable or buy an adaptor. I bought a 50 ft serial with female at one end and male at the other and mated dit with the Optoma supplied cable.

Hello dear friends.

I have been attempting to pin down the source of a problem I have been having with my theater for some months now and I believe I now have the problem isolated.

I have been seeing "posterized" output from my HD81. I believe it is the HDMI 1 input on the VP. I use HDMI 1 for a Verizon HD DVR and in order to expand the number of inputs I front ended it with a Psyclone 4:1 HDMI/Toslink switcher. I initially thought it was the Psyclone and swapped it out. All seemed OK. There was an issue with the Verizon box not being to hold 1080i output if the switch selected another input. I just set it back to 1080i and ann seemed OK.

Till last week when the "posterization" returned. I took the switch out of the line and I thought I had another defective unit. I have a replacement on order from Radiient and it should be here tomorrow.

Then tonight I discovered that the "posterization" returned during some testing. Behold when I put my AppleTV in HDMI 1 it also has the "posterized" image!

I now think that the VP is failing. Heat? Very cool in the stack. I plan to call Optoma to see if I can get a repair.

Any one else seen this? I did a quick scan of the board and did not see anyone with this problem.

I have to say that other than the slow switching during mixed res content and the cooling issues with the PJ (which I resolved with a forced air - forced exhaust plumbing system) I have been very pleased with the HD81.

Best to you all,

John

My theater is highlighted on my web site at: www.johntkeller.com

Hi John,

I've never heard of "posterized" anything so you will have to bring me up to date. Why did you buy an HDMI switcher? Were 3 HDMI inputs not enough? If you would like to see the Integra 9.8 in action with the LV, please come by. Except for bulb failures, my LV continues to perform well. If only this thing would read 24 fps in machines other than the PS3, it would be the cat's meow.

Wow, that is so cool. Is that an extra cost option?

Joe
post #318 of 493
Art,

I have quickly ran out of ports. Both HDMI and optical. The HD81 only suports three and my older Denon AVR3300 only supports two opticals.

I have the following:

Equip/ video/ audio

Verizon HD DVR/ HDMI/ optical

Toshiba HDDVD/ HDMI/ discrete 6 channel

AppleTV/ HDMI/ optical

Pioneer DVD region free/ HDMI/ optical

Playstation3/ HDMI/ optical

Panasonic VCR/ Composite/ 2 ch analog

The Psyclone does simultaneous video/audio switching and I can control it with my URC remote. I works well for about $110!

Joe,

I think I paid around $6,000 plus shipping in November of 2006. They are hard to keep in stock. I can get you a good price on mine!

Silly me. And to think I paid $30 for a photoshop plugin to do my posterization work.

John,

Please take a look at my message #276. See if you can distinguish the lines beween the IRE levels in the setup scales at the top of the picture. It may be that your bulb needs replacing.

Art,

I wish it was only the bulb. The other two HDMI inputs work ok. I believe it to be isolated to HDMI 1. I am going to rearrange the shelf that the VP rests on and see if I can give it some air. I am hoping that I have a thermal issue and not a chip failure in the VP. The rack is cool so I had ruled heat out.

I just want it to work! I develop severe anxiety when anything burps like this. I remember looking at the DVDO processors ($$$) and being thrilled that there was a PJ that had a VP integrated into the package.

Best,
John

Sorry John, I did not read your original comment correctly. Age, I guess. Did you ever get the 81 adjusted to reference levels?

When I was younger, I had the same anxiety issues when things in my system weren't just right. I used to take great pride i absolute precision in video and audio. Today, I find myself fiddling with the controls every time I change programs. I adjust i until it looks good and sounds good to me. It is almost like changing from my scientific background to jusging and viewing the world more like a painter. The AV system is my canvas. After all, why would they put all those contros there if we weren't supposed to touch them?

No. I did not. I got sidetracked with other projects - ignored while building the theater!

Oh so true my friend! There are times when watching a movie I just want to stop it and start adjusting the black level to get more detail in a night scene. Only to remember that I am not alone. That there are six or seven other people watching the movie and that they will rightfully conclude that I am more than a bit crazy.

I tested the VP prior to installation and judged not to be a consideration for heat build up. If it is not heat then the inputs has failed and I will attempt to get it repaired while on my next vacation.

I cannot go to a commercial theater anymore. I cannot watch standard def TV anymore. Curse you "High Def"!

John

Does anyone have any experience using 60ft or over hdmi cables with the hd81 lv. I bought a 60 ft cable from ram electronics with a built in amplifier, but it drops the signal periodically.

This is what I bought
http://www.ramelectronics.net/audio-...odHDMIAMP.html

This is what I am looking at replacing it with

Any comments or suggestions would be greatly appreciated.
post #327 of 493
I use a $95.00, 50 ft. cable from monoprice between the LV and the VXD. No amplifiers and No dropouts ever.
post #328 of 493
Uh oh. The last couple days, I have started getting blue screens. I've never had them before with any of my HD-81s or with the HD-81LV. All I have been watching the last couple days has been HD cable using the DVR so I'm not sure if it happens on other inputs. The blue screen has only been lasting a couple seconds then the image comes back. I just changed the projector to high altitude mode. I'll see if that makes a difference.

The weather has started getting warmer in Minnesota. If that is what is causing the problem, the high fan speed might help. I got the projecter in November, so this will be the first warm weather that the projector has seen.

Have other people seen blue screens that get better after a couple seconds?

Joe
post #329 of 493
I watched for an hour last night with the projector in high altitude mode. I still got the intermittent blue screens. Now I tried turning off 48Hz mode. I'll see if that makes a difference. This is really discouraging. After having three HD-81s fail, I hate to think of shipping a fourth projector back to Optoma. For one of my exchanges, I had them charge my credit card so I could wait until the new one arrived before shipping back the old one. It took nearly a month for them to apply the credit back to my card so I'm reluctant to do that again. Has the slow refund been other people's experience as well? I'm starting to think that this is the supermodel of projectors: beautiful but high maintenance.

I am interested in hearing if anyone has had a similar experience: blue screens that last a couple seconds then resolve.

Thanks

Joe
post #330 of 493
Hi Joe,

Perhaps more than anyone else, I can feel your pain and frustration. All of my units that eventually failed exhibited the intermittent blue screens. The HD81's either returned to normal operation or had to be power cycled into submission. This occurred for a while before it became intolerable. The 5th and current unit has gone blue a handful of times. Each time I had to power cycle it back into operation. Your observations about 48Hz and high fan are all things I did and had sme success with. I think ultimately it boils down to too much stress on the machine that causes a circuit to fail. I have found that if i set my Brilliant color to 5 and above, within 5 min I begin to see splotch faces that are the warning sign that a shut down or blue screen is coming soon. I do not use Brilliant Color unless it is daytime and the windows are open. Now I never go above 2 or 3.

As far as resolving outstanding credit, I have always had to call Warren to get things resolved. He always gets it straightened out within a few days after that.

To be fair, mine continues to function. I do seem to get a greenish-gray tint to plaster walls though. It appears to be a non linearity or deviation from the ideal color temperature at a certain point in the brightness scale, i.e. causing an anomaly in the colorspace. Take a look at the Home Theater article on the HD80. They found similar issues with it although not necessarily exactly where my problem exists.
