Since you already have the service manual, did you check whats the self-test diagnosis for this set? I do not have one for this model so if you can upload it to a file sharing site, I can dowload it and break it down for you.

Standby light flashing is an indication that TV needs service. It prevents the TV from further damage. This is usually due to a power supply failure, or one of the boards has a short on it.

My one year old LCD TV was accidentally hit on the screen with a heating blanket controller while my wife was fluffing the covers, from that point on the TV went right to standby with the red light and will only flash green for a second whether I turn it on manually or with the remote. I was told by another Fixya employee that it was the capacitors on the power supply board which frustrates me a bit because I will have to take it to a repair shop regardless now and pay the same amount even with

I did as the posts here sugested, peeled it apart and manually inspected all of the capacitors. To my dismay I haven't seen one yet that looks bloated or leaky. I have inspected the main power supply board, both display boards and the main board. There were a few capacitors that


If turning it on makes the light blink then its a clear case of open circuit.. Honestly there are lots of components like diodes, fuses, transistors etc., and either of them if shorted create an open circuit. I do not think this is a capacitor proble ... Olevia LT37HVS 37 in. LCD HDTV

I got a Sony Bravia KDL-40WL135. Blank screen. There's two LED lights: red standby and green power light. When I turn on the TV, green led comes on, then after about 30 seconds red led blinks once, then green resumes. The green led stays solid. I think that's a SONY error code, I tried to look it up but can't find anything useful.
