post #2821 of 2855
In theory the slower refresh rate should make RBE slightly worse, but it's a small difference since 24fps is actually played back at a 48hz onscreen (the 24fps is doubled), so the difference is 48hz vs 60hz.

I've tried 24fps for a little bit, but felt I preferred 60hz for the reasons you mentioned.

Don't have a HTPC.
post #2822 of 2855
I run my Dune Base 3.0 in 60Hz playback, mainly coz the response of the player is slowed if in 24Hz playback.
I am not RBE sensitive and 60Hz seems smoother especially in slow pans for me.
post #2823 of 2855
I tried 24Hz and really did not see a difference between 60Hz and 24Hz. My pre/pro will not display volume, etc at 24Hz so I always use 60Hz. I primarily watch movies with TMT6 and use my cable cox.
post #2824 of 2855
Thanks for the responses guys. Not what I expected actually. The results of my searching on this topic seemed heavily weighted toward preferring 24Hz.

I tried a couple of other testcases last night and didn't feel like I could tell the difference between 24 and 60, although it sounds like the difference is really 48 and 60. Possibly these were particularly bad instances of strobing.

Guess I'll keep experimenting. Thanks again!

Anyone had the HDMI input on their HC4000 go bad? I accidentally left the pj on overnight on Sunday (left it on after the SNF game while we decided whether to watch some of the Oak/SD game, but then forgot about it). Turned it off in the morning when I realized, but now it appears that the HDMI input is shot. The pj just shows 'no signal', and the hdmi handshake doesn't complete so there is no audio through the receiver unless I physically unplug the hdmi output going to it, after which audio starts playing fine.
The unit is about 18 months old, but only 400hrs on low so it's been very lightly used.
post #2826 of 2855
Do a reboot---i.e., unplug the AC cord from the PJ for 10-30 mins or so (when PJ is already off!), plug back in and try again.
(assuming you didn't already do this)

And if that doesn't work, bypass your receiver (blu ray/DVD player direct to HC4000, etc), to see if that works.
post #2827 of 2855
Thanks - those are good suggestions and basically what I would have done if I had more time during the initial investigation.

Unfortunately, further investigation confirms that not only is the HDMI input to the HC4000 shot, but the HDMI output on the receiver is also shot. VGA/PC in to the pj seems to work fine, and HDMI inputs to the receiver work fine, but it appears that at some point one side of the link went bad and took the other side with it.

Timing on this is either really good or really bad. We're moving in 3 weeks so I don't really have any time to do anything about this now. There is a big basement media space in the new house but it's not clear whether the HC4000 will be an appropriate fit or not, so I guess I'll be in a holding pattern for a while. Really looking forward to living with the DirectTV box run straight into a cheap 40" TV for the next few weeks mad.gif

Anyone have experience with getting an HC4000 serviced? I'm assuming it's out of warranty, and might not be covered anyway.
post #2828 of 2855
Just call Mits CS (in the back of the manual), and explain exactly what you mentioned here. It would seem that it could be approximated considering your damage appears fairly specific.

Mits is really good/generous with servicing their PJ's (even out of warranty), if you send it in, you might get lucky, but there's no way to tell for sure.

Sad... definitely going to buy 1 or 2 bulbs in case they become scarce in a year or two.

Speaking of which... anyone know of any decent deals on HC4000 bulbs around the web right now? I'm in Canada.

I'm confused, which lamp does the HC4000 take?

VLT-HC3800LP
or
VLT-HC900LP

Thanks for the information. I changed my cable to a longer one (35 feet) and was getting problems with the projector finding my Blu-ray player. Getting different color distortions and noise on the screen. It found and displayed my satellite box just fine. Just the blu-ray player. I remember reading on here that this projector is sensitive to cable length and I wanted to change it but could not find it in the menu.. Thanks for the information.

Hey, one thing you want to do also is make sure you're using a High-Speed HDMI cable instead of Standard HDMI cable.

Standard HDMI cables only go up to 720p/1080i at certain lengths. High-speed can handle 1080p at long lengths. Just double check that first.

There's a possibility you're using a long length standard HDMI cable which is limited to 720p/1080i (which is why your Satellite Box works just fine [probably set to 720p or 1080i] vs. why your Blu-Ray player doesn't [probably 1080p])

I'm not telling you to go out and buy an expensive HDMI cable, you can find cheap long high speed cables on MonoPrice as well. Just be sure when you buy to check the cable specs and make sure it's high-speed. I think even Fry's has some cheap high-speed long length cables.

I was wondering that to. I got the cable included with a 720p projector that I bought off of ebay back in 09, It looks like a heavy duty cable but I don't know what type it is. I turned off everything and turned on the projector and blu-ray player with the cable length changed to the longer setting and it found the player. I am hoping it will work ok. I just mounted the projector to the ceiling and I dont want to think about crawling in the attic again and taking down the projector to route a new cable. I will keep my fingers crossed that it keeps finding the blu-ray player. If not looks like I will have to upgrade the cable.... Thanks for the information that you posted to me.

I went on to the Monoprice webpage and decided to go with the High Speed HDMI Cable with RedMere. My projector is finding the blu-ray player but I do not think the picture has the same punch to it as when I was using a shorter cable that I know is a high speed HDMI cable, I spent all this money for the projector might as well get the right HDMI cable for it.. Thanks for the link to the Monoprice.

There's basically 2 things that will happen when your HDMI cable isn't up to task, no picture, or 'sparklies' --which are like little white dots that sparkle about on the image, kinda like video static.

There should be no difference in 'punch' between HDMI cables.

Maybe someone can help me figure this out...

I've had my HC4000 for a little under 2 years. Last month I noticed a dead pixel just appeared out of nowhere. Then throughout this month, I've noticed the screen has been flickering and having issues holding the signal, so I added a second repeater. That seemed to fix the flickering for the most part, but it still happens occasionally. Now, a few days ago I noticed a "halo-like" circle in the lower right area on the screen which could be a dust particle on the optics. And finally, within this month, it made a loud grinding noise once while starting it up.

Like I mentioned, the projector less than two years old. I'm the original owner, and the bulb only has 400 hours on it.

Is the projector is starting to die, or are these anomalies happening all at once just coincidence?

Factory warranty is 2 years, I would contact Mitsubishi support and get it fixed. I have had mine almost 3 years, I have no dead pixels and never had any unusual noises. I have about 3800 hours on the projector.

3800 hours with the original bulb? still looking good? good enough luminosity? Mine is about 1400 hours in almost 13 months and still looking superb but the luminosity is like 25% less.

I hope that with 3000 hours the proyector luminosity is strong enough.

Sorry for my poor english.

It still works I just decided to replace it at about 1800 hours.

I just replaced the second bulb (still works) with a new HC4000. Price at Newegg with rebate, was six,seven,oh not much more than 2 bulbs.

REASONS I BOUGHT ANOTHER HC4000:
1. It is an outstanding projector especially when used with a Darbee Darblet
2. I use a projector 1350+ hours per year. Projector + bulb cost per hour is low.
3. I prefer DLP and have an expensive Stewart Firehawk screen that is excellent with DLP.
5. Long throw distance, my projector is 16' 2" from a 110" screen. Places the projector 3' behind my head. Helps with noise.
5. I can get a Mitsubishi extended warranty and add up to 3 years on the warranty.
6. I now have a spare I can put more hours on.
7. I have little interest in 3D or 4K technology at this time.

Of interest, light leakage from around lens was significantly improved. Old serial number is 018XX new one is 198XX. Looks like they made close to 20K units.

Thanks for the explanation John P. smile.gif

I was tempted to buy the Darbee some months ago when the price was 250€ but it costs now 350 € in Europe.

I am extremely happy with the HC4000, superb projector. smile.gif

lol - same hear! 680 for the "spare" 4000 after mits rebate from amazon (730?) pre-rebate. I've got a 3800 for the last 3 yrs (4000 came out a couple months after I got my 3800 - my understanding is that they are essentially the same).

for 680, its a better deal than 2-bubs instead for same $.

couldn't care less for 3D (gimmick) - hell there are PC programs to convert your vids if you want - using the old Blue Green scheme might for fun for sheets and gigs - that type of 3D works on 2D equipment.

Yeah, it's a good deal for sure. Also an HC3800 owner here smile.gif

But, the deal is dead and the HC4000 is discontinued ---and out of stock at newegg, and others.

At that rebate price it would get me thinking of getting one....after some thought, for 'me'>

Pros>
> Upgrade from my HC3800, but honestly, probably so slight I wouldn't notice
> Good deal, Good PJ, kinda like a lamp purchase with an new HC4000 thrown in for $300 more
> Discontinued, so if you want a new one, get it now!

Cons>
> Upgrade from my HC3800 will probably be unnoticeable (and if so, canceling out the slight 'pro' from above)
> Calibration: I'm no calibration expert, and calibrating by discs (have like 3 different ones) isn't fun, nor complete...usually tweaking by eye before finally being satisfied (especially with gamma). Probably the #1 con for me in this case.
> Hours: I actually only have about 600 hrs on my original HC3800 lamp! AND, I have an untouched extra new lamp that I got on a new lamp rebate deal during my original PJ purchase. So I'm obviously not an heavy user.
> Discontinued: I would assume Mits's support will still be outstanding for the 2-3 years warranty period....but we all know about assumptions...

Ultimately, even if this deal was still alive, I would probably pass----very reluctantly though. I would like a true upgrade....unfortunately, as much as I love DLP for what it 'was', moving forward into the future it appears DLP hasn't, and will not really progress much further. I'm looking towards a JVC in maybe 2 years time....by then I would hope the JVC's have addressed my main concerns, i.e., lamp life (looks like they might have already got that handled), optical block issues (again, seems to be getting better---but failures right out of warranty still scare me), JVC's notoriously bad CS (compared to Mitsubishi's), and performance wise, increasing ansi contrast and decreasing calibration drift.
By that time, I would hopefully be well into my 2nd lamp on my HC3800 and hopefully patting myself on the back for waiting it out.

I received my warranty replacement projector a couple days ago. Before I say anything about it, has anyone else here called Mitsubishi for a replacement? I'm curious of your experience.

On the phone everything was fantastic, and a replacement was sent.

Receiving it is a whole different experience...

SHIPPING: it came in a large plain box stuffed sparsely with foam. The projector was in a plastic bag and jostling all around the inside of the box during shipping. At first inspection, the casing of the projector was scratched and beat up (my old one is a perfectly smooth and shiny black finish). There was no remote, no power cord, no lens cap, nor anything with it. As a replacement, I guess that is acceptable as my current accessories work with it. ...Though, I would think AT LEAST a lens cap would be attached.

STARTING IT UP: I noticed there was a big fingerprint on the lens. The remote works ONLY if pointed directly at the projector (my old one works anywhere in the room). There was a few second delay after the projector responded to the remote to when it actually started (my old one would start up instantly).

PERFORMANCE: The HDMI input is quirky. Neither my PS3 or HTPC was recognized. I had to unplug the HDMI cord several times and replug it back in to finally get a picture from each device (my old one never has an issue). There is massive amount of light leakage around the screen (My old one only has minor leakage below the screen). The fan is loud in low lamp mode and distracting (I could barely hear my old one). And to top it all off, the lamp hours were not reset as it says 1024 hours. With everything wrong with this replacement, I question if the lamp was even replaced.

PICTURE: The picture seems okay. I haven't noticed any dead pixels, halos or color change.

I'm calling back Mitsubishi to see what can be done. When I spoke to them to get the replacement, I asked "what if this replacement goes bad" they said I only get one replacement. But does that include if the replacement is ALREADY bad when delivered? We'll see.

Needless to say, I'm disappointed with the replacement.

Yikes, that's terrible!

I went through a couple of replacements during the HC3800 teething months, and they all came well packed---in original boxes that were then packed in a bigger box. No issues with the packaging or shipping.

For the rest of your issue---yikes again. Hopefully this will be a case of Mits's excellent CS coming through with another replacement sent out smile.gif

I use Projector Lamp Experts. They sell the OEM manufacturers lamp as well as what they call an "alternative lamp" which is not OEM , but at a cheaper price. I've ordered the OEM lamp and they have always come in the manufacturers box with the manufacturers warranty. They have a Canadian site too so that might be a plus for you with shipping. http://www.projectorlampexperts.ca/item_detail.aspx?LampProductID=2105
