Hi
I picked up this 50" LED tv (Changhong model LED50YC2000UA) that suffered a power surge and it no longer turns on. The red standby light is on when plugged into the wall, but nothing happens when the power is pressed.
I opened it up and physically, the power supply board looks good, no burnt marks or bulging caps. I tested the voltage reading from the PS and got the 12V going into the MB, but did not get the 24V going into the LED board. I am wondering if this is a sign that the PS is bad or that the 24V will only go on when the MB is working properly and sends a signal for it to turn on.
I am attaching pictures of the tv, hopefully someone can direct me to the problem.
Thanks
