I have a sony LCD projection TV Model # KF-50XBR800 and when I go and turn it on my standby button flashes red and then picture comes on for about 10 seconds then it shuts itself off. Can you tell me what...

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

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.
