Try to replace the Main Power Supply board first.

was that capacitor damaged?

1) Is the TV plugged directly into an outlet or is it plugged into another device, such as a cable box or audio receiver? If it is, try plugging directly into a wall outlet. Sometimes, devices like cable boxes don't provide enough current to power on more powerful newer TVs (like Plasma, LCD, etc) .

2) Check the manual to see if the flashing LED is a code for something you need to troubleshoot. The number and color of flashes may correspond to a problem that may or may not be easily fixed.

Hope that helps. Let me know how you make out.

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%.

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!
