Question about Sony BRAVIA KLV-40U100M 40 in. HD-Ready LCD Television
I have a 40" Sony Bravia LCD HD Monitor purchased from Sears in 1/2007. I worked and looked great for about 6 months. Last month the problems began. Seemingly at random, the screen goes black and the power light turns off. It might go out for 5 seconds or so then comes back on. It does this repeatedly no matter how long the TV has been on. At first it was annoying, now it's gotten worse to where its unwatchable. I have it plugged directly into the wall outlet by itself (nothing else plugged in). I've tried it in different outlets as well and it doesnt fix it. Also, I have plugged other electronic equip into those outlets to make sure there is sufficient power supply (i.e. surround sound stereo, cable box, PS2, wireless router) and all other equipment works fine. It's under warrenty and I have a sears tech coming on 9/27, however, I would like some background on what it might be before the tech comes. Plus, it's hard to wait 2 weeks without a working TV. HELP!!
My t.v. just went out as well...how convenient because my warrenty just went out a couple weeks ago. From what I have heard from many different repair people that the problem is with the power supply board. Since I also bought the tv from sears here is my plan. I puchased the new board through sony which is only $150. I am going to swap it out with the old one and pray for the best. I have talked to sears about getting the buyer protection for the tv after a year after i purchased it and they will charge you a higher price for the warranty as long as the tv is still functioning. If all goes well with the repair i will get sears on the phone instantly because a service guy has to come out and verify that it functions properly.

I have a problem with my sony bravia KLV-46V200A.
Screen is black out and power light is flashing red six times per cycle.
What should I do. I bought it about a year.
Thanks for your solution.

Check the U24 (CPU reset IC) on the "A" board. It may be burned. If you have a DVM (voltmeter) check for 3.3V across SW1 connections near this device. If you don't have 3.3V, U24 is bad. This part is not available from Sony. The TV may work if you just remove U24 from the board. I posted this fix on Agoraquest also, you can read more there (I'm "Roundabout" on that forum). Hope that helps.

Uh, oh. I just purchased the same tv. I would love to know if replacing the board will fix the problem forever. If the boards are not good, how would a replacement help if it also lasts a short time?
