About a month ago my set started having a hard time turning on. It was taking longer and longer for the picture and sound to come on until last night when it just stopped working. I can hear the relays clicking as it attempts to power on but after about 30 seconds it goes back to standby. I have read about the blinking standby light diagnostics, but it blinks about 10-11 (not sure if the first power on blink counts) times and the previous messages only talked about problems up to 8 blinks. I removed the rear cover and looked for burned resistors and loose or cold solder joints. There was nothing obvious found. Do you believe the set is too far gone or might there be an easy fix?

Re: Sony 32XBR400 Wont Power On
I do not believe the set is too far gone. The standby light blinks codes up to 7. If the standby light blinks more than 7 times it usually means that there is a short on the clock or data line. There are several small zener diodes connected to the clock and data lines in a couple of different places on the main board. Many times I have seen one of the zener diodes become very leaky, usually along the back of the board, loading down the clock or data line which produces the symptoms you are seeing. If you have no experience locating shorted zener diodes and unsoldering and soldering small parts, allow a qualified tech to service the set for you.

Check all the solder terminal at its main power regulator section circuit. Any loose solder terminal can poise this type of problem. Resolder all the suspected solder terminals by applying a little more solder. If you wish to get more details, check this site.
Should have been 3300 UF 10V caps that were bad? Shouls have been replaced with 3300UF 18V. 50V is huge. If it was replaced with a 50 the polarity may be wrong or the cap it too big to be seated property. Sometimes the caps just dry out and even a normal looking one will be the culprit of no OSD. Are you getting an LED fault code blinking? That should be a red led. Do you hear the relay clicking.? When you replaced the caps did you charge them? Just plugging in the set without trying to power it on for about 20-30 mins. I may be able to help you

I realized that there is a 90 day warrantee on parts and a 30 day limited warrantee on labor for the repairs that were done. As I stated, the original problem was the picture shrinking after a few minutes of the set being on. The repair firm took my control board with them. When they came back to install the repaired control board in my set there was a load spark during the installation, after which I had a black screen and no sound. The repair firm took my set them and installed a "CAP Kit", a STRM6511, and a "D1881". The set worked perfectly until two days ago.
I called the repair firm an they are coming out this Thursday to check out my TV. I am hoping the problem is related to the failure of one of the parts installed to fix a similar problem which occurred after the sparking incident.
