Does this sound like I need a bulb replacement? - Blu-ray Forum

Steelmaker · 01-08-2009, 01:19 PM

I have a Sony KDS 60A2000 tv. I bought it in March of 07. Here lately when I turn the set on, I've started noticing a faint "yellowing" around the corners and the edges of the screen. It's pretty subtle and not really noticable when there's a vivid picture being displayed but when it shows a dark scene or if the screen is black, you CAN make it out.

Can anyone tell me, is this the result of my lamp going out? The picture itself doesn't seem to be any dimmer, nor am I noticing any color fading. It's just that yellowish haze around the edges and corners of the screen.

Wow, I mean can no one answer this one for me?

Hi,

Do you smoke? (serious question)

It could just be that you need to clean the inside and the lamp 'house' and fan.

No, we are a smoke free house. Although our house does seem to produce a lot of dust.

I actually thought about that. I thought that maybe I need to get a can of air and spray the inside of the set and the lamp.

If you want to hear my guess id say

Light engine, sony rear projections always have problems with those.

Thats how my buddies started was discoloration around the edges. I believe his was blue though.

Just a random guess without being able to see it.

I've got a 50A2020, my bulb went out a few weeks ago. There was no warning, no visible signs of it wearing out. Just *poof* as I turned the set on, and a flashing "bulb" light on the front. Sounds like it might be something else.

Thanks TV guy. I took my lamp out last night and blasted it with air. I also blasted the inside and got all of the dust out. I re assembled everything and turned the set on. It appears the green haze is still there.

After reading on AVS it appears that this is a common problem with my particular model and that Sony has extended the factory warranty on this model through 2010, regardless of when you bought it. I'm going to contact Sony today and see about getting it repaired.

UPDATE: I contacted Sony's customer service support and they indeed said that this is a common problem with my particular model. They said that parts and services are covered for repair for this problem through 2010. The woman gave me the number of a local Sony certified repair center and I am supposed to call them and setup a time for them to come out and replace my optical block.

phlydude · 01-09-2009, 08:21 PM

This is the reason you can't fine LCoS tvs anymore...Sony had a green blob, jvc a yellow one. One of the filters on the light engine actually begins to discolor and warp. The more you use the tv, the worse it gets (the lamp heats and warps the filter).

It's a shame, I have a great picture on my JVC LCoS set but am starting to notice a yellowing in the screen...good thing I have a ext. warranty!

TVguy86 · 01-09-2009, 09:38 PM

Cool

Glad that its a free fix. Its like 1000 bucks if you dont have any kind of warranty.

At the tv repair place i worked that was the most common sony repair on rear projections.

Not to discurage people from purchasing them just do your research. Dont just buy flat because everyone else is.

Hey TVguy,

Something I forgot to ask the Sony rep was, has Sony actually FIXED the problem with these light engines or can I expect the same thing to happen with the replaced part 2-3 years down the road? Do you happen to know?

rdomingo77 · 01-16-2009, 01:48 AM

TVguy86,
I have the same problems as your friends, i have blue haze/discolouration around the outer edges of the tv frame all the way around and even a rectangle shape with blue haze too in the middle of screen. I can only really notice it during dark scenes, but its getting annoying. Did they get it fixed? What was the problem? It doesn't sound like an optical block issue.

phlydude · 01-16-2009, 12:55 PM

This is all part of the many reasons why RPTVs are being abandoned...light engine issues, expensive bulb changes, dust affecting the image, etc.

I don't know if Sony ever truly fixed the issue...you can see people say they have no problems with replacement parts while others say that the issue came back (and for some, multiple times)

Yes he did get it fixed. Sony replaced the whole light engine. He did have an extended warranty so that took care of it. I believe that sony extended the manufacturer warranty for these tvs becasue of this light engine issue. I would call sony and see if this is true. Or perhaps search on the sony web page.

Not quite sure but i would assume they addressed the issue that made them go out so early.

I guess the thing that i noticed the most with alll HDTVs is that they break. Lol for lack of a better way to put them.

They are vastly more complicated than tube tvs, have multiple boards, mulitple microprocessors, and are just 100 percent more complicated. So i would like to say yes 3 years from now you will be fine but its soooo hard to konw.

rdomingo77 · 01-18-2009, 03:13 AM

Thanks TVguy86...i'll give the sony reps a call first thing.

Steelmaker · 02-09-2009, 06:38 PM

Arghh!! Well this dilemma just continues! I took my set to the nearest authorized Sony dealer for repair. I get a call from the place today and they tell me that they see no visual problem with my set. I explain to them that it has a yellowish green haze around the corners and edges of the screen and that it is mainly noticable on solid black or white screens. When watching a movie it is not really noticable. When I described this to my Sony rep, he said that sounds exactly like a defective optical block. However the repair shop said that it has solid readings on blue, red, and green and that usually if it's a bad optical block, that is not the case.

I know I'm not imagining this! I know what I see and even my wife sees it. Does anyone have any suggestions for me?

aheineken · 02-10-2009, 01:11 AM

My Samsung (2.5 years old) has the exact same problem. Luckily, I got the extended warranty (3 years). I had someone come out and look at it last week, and the first thing they asked me is if I smoked. When I answered no, they mentioned something about replacing some "chips". I haven't heard back from them...I'll give them a call tomorrow.

Wow stuck between a rock and a hard place. It sounds like no one wants to warranty this set for you, even though it has known problems. I would say go to the service center and point out what you see to them. Perhaps they didnt identify your problem. I cant see how but... Then perhaps tell the sony rep about the service center saying nothing is wrong. I just dont know where you go from here?? Again i would go in and show them what you see and hopefully that will get you somewhere??

Have them connect a dvd player and insert a b&w movie to play. That should show the problem right away.

Going through the same thing with my SXRD. The optical block is being replaced tomorrow under ESP so hopefully it will be back to where it was originally. From what I understand, the OB will go tits up again in about another 2 years, but by then I'll be rid of it anyway so it doesn't matter. Won't be replacing it with another Sony though.
