I have a samsung ln-t4053h that had a bad caps. I replaced the caps and the tv turned on fine and i put a flashlight to the screen and the screen turns on but the backlight is on 10 and it looks like its not on at all so that leads me to believe the backlight inverter.

Vizio VT470M no picture, no sound, no backlight. Power supply board looks good all voltages appear correct (24V, 5V, and 3.7V) and no "bulged" capacitors . When I unplug unit for two hours, the screen comes on normally backlight comes back up and picture is normal, but changing the channel causes it to go dead again.

Vizio VP322. Replaced 3 bulging capacitors on power supply. TV worked great for about 2 days. Now it wont turn on. The Vizio is lit up orange on the bottom but thats it. If I unplug the wiring harness going to the input board the screen will light up black but goes back out as soon as plugged back in. If I unplug all but the AC power cord I get 5V off power supply on one and 200 on both VS and VA. I'm not detecting power at those when all harness are plugged back in.

I have a Phillips 32PFL5322D/37 tv that is about 2 1/2 years old. Recently the TV stopped working. All I see is 8 red blinking lights when I try to power-up. After reading multiple threads and suggestions I replaced the Power Supply Unit but still no change in the 8 red blinking lights. I have a power aux board coming in the mail and I plan to install. I am out of ideas here. Any other possibilities? It seems everyone is having the same problem with this TV. There must be a reason.
