Main Power Relay does not energize rest of system.

This TV has a two stage power Supply with a Relay after the low voltage circuit that keeps the IR Remote Circuit energized.

If the Red Light on the front lights up for 1 or two seconds then goes out then the High Voltage mainboard may not be getting enough power.

There are LETHAL Voltages inside ind should only be serviced by trained technicians.
