bandyka Posted March 22, 2016 Posted March 22, 2016 Hello All, Any idea what might be the issue? I was offered a 500ES for a very good price but it has this issue. This is how it was described: the bottom few lines have greenish tint.this have zero effect in 21:9 format.and only noticeable on 16:9, (and thats only on certain screen colors, and even then you dont tend to notice when you are engaged in the movie.) Should i steer clear of this unit? ...or is it something that is not much of a concern? Only has 250 hours on the clock. Thanks
Quark Posted March 22, 2016 Posted March 22, 2016 (edited) Some photos would help if possible. Best case is chromatic aberration due to lens limitations, especially if being used at the limit of vertical shift (albeit greenish tinge is not something I've seen before with CA). Worst case is faulty light engine or a more substantial lens problem. IMO approach with extreme caution. Is the warranty transferable on these (assuming local delivery, not grey import)?

bandyka Posted March 22, 2016 Author Posted March 22, 2016 Thanks I am waiting on some images and will post as soon as I have them. Someone warned me that some of these units run so hot that the light engine fails?? Apparently a $6000.00 fix...
betty boop Posted March 22, 2016 Posted March 22, 2016 Have read of degrading panels on sonys, not sure if related.But really why take on someone else's problem and grief. Unless have a tech look at it with a quoted estimate to repair bit hard to say anything. Even a tech I suspect would be hesitant to suggest anything before physically inspecting the unit diagnosing the problem. And even techs get wrong sometimes.I had a projector once with an issue like this under warranty, they replaced the light engine which is pretty much the guts of the projector. But didn't completely resolve and then had another attempt to fix eventually they just replaced the entire projector with an updated model that was fine.Projectors are just so fragile delicate things, suspect with number of 2nd hand projectors come up there be a better 2nd hand option if that's what you are chasing
bandyka Posted March 24, 2016 Author Posted March 24, 2016 (edited) Yes I agree with all of that but the price is just too good, less than $4000.00 and is from a reliable source. Here are some images. To be honest I can't see anything out of place: http://postimg.org/image/gklk9t5c9/full/ http://postimg.org/image/dch2wrj2h/ http://postimg.org/image/dnyj9izih/full/ hmm what to do?? If its a failing optical block it will cost $8K to replace.... Is it too good to be true? Edited March 24, 2016 by bandyka
Quark Posted March 24, 2016 Posted March 24, 2016 Last picture shows it. Looks like the optical block is shot and typically it will only get worse (i.e. become more apparent and affect a wider area). Why wouldn't the vendor claim it on warranty?????

If its a failing optical block it will cost $8K to replace.... Is it too good to be true? Can see it on the bottom pic you posted link to. Across the bottom of the screen on the white plate and also across onto the orange plate. Given this unit is less than 3 years old and has a 3 year warranty, I would be concerned it's not being repaired under warranty.. which may suggest it's a grey import? Otherwise the warranty should cover it.
bandyka Posted March 25, 2016 Author Posted March 25, 2016 (edited) Yes its a grey import, and yes I am suspecting a block failure is to happen gradually going by what everyone suggests. I'll stay away from this. Thanks guys for the feedback appreciate it. ...and yes I can see it now on the photos I was partially blind last night being too late for it:) Edited March 25, 2016 by bandyka
betty boop Posted March 25, 2016 Posted March 25, 2016 projectors grey imported are a very bad idea. people buy them thinking a bargain but its very short sighted a view and can end up in a big mistake. hopefully a reminder for people to stay away and if there is something to be bought local its a projector.
bandyka Posted March 25, 2016 Author Posted March 25, 2016 Which is why I asked here just to reinforce my thoughts. The price was too good to be true I knew I should not but someone had to tell me "don't do it". Thanks
bandyka Posted March 25, 2016 Author Posted March 25, 2016 The only question is now: should I get a discounted 300ES or should I save up and fork out mega bucks for the 520ES? I feel the 520 just isn't worth the asking $$$. The JVC are no option for me no matter how good they are.

I feel the 520 just isn't worth the asking $$$. The JVC are no option for me no matter how good they are. Before sinking big money on one of the Sony 4K projectors, I'd recommend you pop over to AVS and read up on the contrast degradation issues that are emerging even after low hours. Some of the measured fall-offs in contrast ratio at low hours are quite extreme. Those who run their pjs for long hours don't seem to have the same level of contrast fall-off, so sounds like it might be related to short thermal cycling (switching off after only an hour or two of viewing).

Agree, projectors (especially higher end units) are one item I'd never grey import - too fragile and too costly when things go wrong.

I feel the 520 just isn't worth the asking $$$. The JVC are no option for me no matter how good they are. is this because of the casual gaming requirement ? just buy a cheapo ~$1k benq for that even a 2nd hand unit. no point chewing up a top line projectors bulb on gaming hours on end or having to worry about the hours clocking up. and then buy the best projector PQ wise to you eyes for all else...
bandyka Posted March 25, 2016 Author Posted March 25, 2016 (edited) Never understood such comments on the gaming side of things, obviously you are not into it but for someone who is its just as important as movies for you especially the 4K feature as games can utilize it to its full potential. Please let's not start that debate again Yes I've been reading up on the issues that occur with them for a very long time now and pretty much aware of them and am happy to take my chances as I normally do long sessions. My only dilemma is whether the 520ES worth it over the previous generation at current prices? I am extremely pleased with the 40ES that I currently run so Sony is fine in my books.

Those who run their pjs for long hours don't seem to have the same level of contrast fall-off, so sounds like it might be related to short thermal cycling (switching off after only an hour or two of viewing). An update: over on AVS someone has linked to this - I can't comment on how accurate the claim is of humidity/condensation being the cause of contrast degradation. Quoted below: A forum member who's pre-ordered a 5000ES contacted me about the issue. He spoke with W.Mayer on the phone (you might know him from the $20K+ forum) who had the several Sony Japan SXRD engineers and executives to his home a month or two ago to demo a pre-production 5000ES. When he asked them about the issue they told him it has to do with humidity and condensation building up on the chips. Apparently even a tiny amount of water on their SXRD chips will degrade them over time. As these chips go from hot to cool they attract condensation on them. This is a copy and paste of what I was told. Remember, please do not post this on the forum: Quote: I have been told this is an issue of humidity and built up of condensation on the panels. That's why it seems the more frequent the projector is used the less the issue. I also also been told even having the unit in a clean environment, with a dehumidifier can go a long ways helping the issue. I have been told there is some sort of fix, maybe not permanent, but something that should help these chip degrade considerably slower. The "fix" wasn't talked about in detail but I suspect a new coating or material change to the SXRD panel to help fight against what any moisture on the chip does to contrast. From what I understand, along with some sort of new coating on the chips, the fact that the 5000ES is liquid cooled will also help this problem. This should help keep the chips much cooler while they are in use, so there will be less change in temperature from when the projector is running and not running, and limit any humidity / condensation issue.
bandyka Posted March 27, 2016 Author Posted March 27, 2016 Good find! Well its no longer an issue for me as I am now 98% convinced that a JVC X5000 or 7000 is the way to go for me. I'll take the plunge and will see how much of an issue gaming is going to be. I just simply cannot get past the features they offer such as HDR and full UHD compatibility. Not to mention half the price compared to the Sony. Been reading here as well and it seems the image quality of the new X range is unbeatable at the price point. Some members may be pleased to see I caved in finally

Owen Posted March 27, 2016 Posted March 27, 2016 Been reading here as well and it seems the image quality of the new X range is unbeatable at the price point. The X9000 can't be bettered at any price, its currently the top of the heap.
bandyka Posted March 27, 2016 Author Posted March 27, 2016 I've heard they are spectacular due to their hand picked optics? Everyone I am talking to are saying the 5000 is the true hero and is now on special and comes with 3 pairs of glasses.
Owen Posted March 27, 2016 Posted March 27, 2016 Since the price deference between the X5000 and X7000 is less than it was between the X500 and X700 the X7000 is the sweat spot IMHO. If you want to save money an X500 is an option, not as bright as the X5000 but darker blacks.
bandyka Posted March 27, 2016 Author Posted March 27, 2016 Definitely not the 500 it lacks the features I need. I am a little concerned about the bright corner issue with the 7000.
