Question about Sony Grand WEGA KF50XBR800 50" Rear Projection HDTV-Ready Television
My sony kf-50XBR800 tv turns itself on and off continuously. Put it on, stays for 30-60 sec, then no picture, audio stays on 1-2 seconds then totally off. The red light blinks 34 times, then comes back on and the cycle repeats until I either unplug it, or manually turn off. I've been searching the net, maybe the lamp, but lamp light doesn't light. Heard about thermal fuse issues. The set was purchased in 2003, never replaced the lamp. Any thoughts?? Is this something someone like myself can fix, at my apprentice type level?
The usual problem is that the lamp needs to be replaced. However, there is no guaranty that lamp replacement will correct the problem.

I just purchased a replacement lamp off ebay and the TV is working fine now. Color looks better too (which I guess I should have expected). Search for "REPLACEMENT LAMP SONY XL-2100U" on eBay and look for seller "niosales". I paid $129 out the door. Their are other auctions for this lamp you can check out. Make sure you look at lamps that include the entire lamp housing, not just the bulb.
