Sony KP-53V90 No power dead Can't Post
Guys I have a Sony KP-53V90 that I am ketching hell repairing. Here is the problem the TV has no pwer no led indicator nothin. The fuse is not burned, the HOT seemed like it was burned when I test it, but got a replacement and the reading was the same, so that was good. I am getting the standby 5v up to the control panel, but no power no led nothing. Fusible resistor is good as well as the main fuse. Please tell me where else to poke around as this is killing me. Thanks guys.

check on the power supply regulator to see if you have full rectified mains volts.also check for short circuits on the secondary voltage supplies.a short somewhere will stop the power supply from starting.
