Hi!

This more then likely a back light inverter board issue! It can be intermittent or just black an non responsive.

    Hi!

    It is also plausible that the power supply has some bad caps Capacitors), that are bulging on top and or leaky (brownish stain). This feeds power to back light inverter!

Rca tv/dvd combo L32HD32D powers on and for 2 seconds shows, Please Wait, on the screen then goes black. What do i do?


After the screen goes black, do you still have sound or you have none but a blank screen? If you have no picture and sound does the power LED in front of the tv indicate that the set is on, or does it go into standby? Please provide this info so that I can help you with your problem.

Sai.

Dark screen, no sound


1. Check the Power Supply board to see any blown cap? Output voltages are normal?
2. If Power Supply board is ok, replace the Main Digital board.
