you should check on the power regulator, usually there are several components that cause damage with symptoms like that. I will try to describe some existing components associated with such defects:

1. Elco 100uf/160 or 220uf/160 Volt, may have been damaged / leaking or dried fluid
2. Horizontal output transistor, such as D1554 or similarities
3. Zener Diodes (5Volt) for the IC Program or 12-volt regulator on the main Power (Live Area)

Also check the voltage B +, must be available 115-volt DC, when the TV is turned on. And 5-volt voltage to the IC program should be available even when the TV in stand-by mode
