Lightning strike Lost picture and sound. All leds on power board are lit. led is lit on big board where the secondary power feeds in. The led next to the high voltage coil doesn't light. Was wondering if the strike hit the antenna input and fed through the back door, or went through the power supply. one voltage reading is -38 volts were the block diagram says should be +39. Should I purchase a schematic fo $20 or is there a site with free downloads? Don't know where to find a test point on the secondary power supply. Old TVs used to say the voltages on the boards where test points were
