SOURCE: any ideas?
1) Replace C2663 by 2020 021 91677 (100uF/50V, 105°C).
2) Place Schottky diode 9336 247 60133 on pin 7 (+) and 8 (-) of IC7650,
to avoid negative pulses, resulting in this bad startup behaviour.

Not a fix, but it got my tv on.
I removed the back and tried the power switch.
I located the relay that was clicking.
I have two blue relays in the middle of my power board.
I placed a hair dryer over the relay for a few minutes.
After four tries of the power switch and it stays on!!!!!
Heat keeps the relay from just clicking off.
I don't know why.
This will at least get the tv on though.

The problem is in your cable connection on the back of your monitor or Box. I had the same problem and solved it by reattaching the VGA cable that was loose.

The problem is in the standby power supply. the standby power supply generates the 9 volts and the 5 volts requird by the tv. If you measure the 9 volts source, with only the red light on, the correct voltage is 9 volts. However if the 9 volt measures 6.5 to 7 volts it is too low and the startup relays cannot operate. My set is a model 42FR9954/17S. In this set if capicator, 2603, is heated the voltage climbs to 9 volts and the relays work. If cold air is applied to the capicator the relays fail to operate. Replace capacitor 2503 and the problen is fixed. This capicator is: 47 Ufd, rated @ 450 volts, and is 20%.
