Question about LG 42PQ30 42 in. Plasma TV
About 15 to 20 minutes picture goes out, sound stays on... This continues on and on
Your TV is a plasma, it has no backlight or inverter board, First confirm your picture source or video cable is not the problem, Try another input, if it is OK, then check the TV. You must check Vs and Va voltages or Y Sus board when you loose video. Do this only if you are comfortable around electricity, You can hurt yourself or render good parts useless.
