Question about RCA Televison & Video
Possible that the processor controller is cutting OFF the main +B power to the main board due to some errors in the board. It will be important to trace the +B voltage to the driver units, wil need to use a multimeter to check for short in the board. If so, disconnected, desolder and test with the power switched on.
Possible driver outputs, transformer , capacitor or IC can be short. Confirm and replace.
