SOURCE: power & OPC lights keep
That signal the fact that the power source is in protected mode - a component has failed in the tv and now acts as a short. When the power source tries to start the failed component starts to draw so much power that the voltage drops; this trigger the protection system of the source that shuts it down to save it from frying.
To fix the tv you will need to open the tv and test the voltages on the output rails of the power source to find out which one is triggering the shut down. Then just follow it to the failed part. This requires a good electronics experience.
In your tv the most usual part to fail is the sound board: the radiator on the audio amplifier is undersized so the amplifier overheats and fries. The sound board will have to be replaced - a $250 job at a repair shop.
