Re: Sharp LC-50LB261U - has audio, no picture

Newbie here. I have the same tv and it has sound but no picture. If i shine flashlight at it in dark room I can see a picture. I have checked the voltage on the led plug with power on an I get 0 volts. Do you guys think i need to replace the power supply board or do I need to try and get the leds to turn on by process mentioned above?
