Before you replace the lamp I recommend trying to clean/dust the lamp component and lamp plug in area. I had the same problem and was able to resolve it by simply blowing the dust off the lamp components and fan. Use a can of high pressure air to get into the cracks and crevices.

SOURCE: The screen turns blue after about 2 minutes of turning on the TV

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

My sony rear projection tv flickers green then shuts down ,any help


Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service

I've been having this problem for a while. when I'd turn the tv on I was able to watch it for about 15 minutes. suddenly the picture and voice would turn off, but the green power button was still solid...


Sounds like it may be a power supply issue. I don't know what "modules" the tech replaced, but I would have advised you to scrap the TV for a newer model as they can get pretty expensive to find and replace parts of the older rear projections. Sorry I can't be more help to you.

TV wont turn on, makes buzzing noise and shuts off


I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.
