Question about Sony Grand WEGA KF50XBR800 50" Rear Projection HDTV-Ready Television

2 Answers

Sony grand wega started turning on and off continuously

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?

    My Sony Grand Wega 50 inch has the same problem, the power will go on and off every 30 seconds. Never replaced the lamp but the lamp indicator light on front of set does not illuminate. Any suggestions?

    When I turn on the set, it comes on normanlly for about 5 sec., then turns off and the green ready light blinks appox. 25 times. The set comes on again for 5 sec...this happens over and over and over...only 3.1/2 years old...pretty fed up and aggravated.

    I have the same problem with my Sony KDS-60A2020, standby LED and lamp indicator does not illuminate. I called Sony support and told me to call and pay for technician for service. I was told its not the lamp. Any help out there?

The usual problem is that the lamp needs to be replaced. However, there is no guaranty that lamp replacement will correct the problem.

SOURCE: sony kf-50XBR800 tv turns itself on and off

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.

SONY GRAND WEGA KF-50WE610 can't turn on TV screen.


Ths 5 blinks usually indicate an AKB problem. There is a break in the video path. I'll look up your specific model and post the results here. Please update this if you wish to attempt the repair yourself.

Thanks,
