Question about Samsung LE40R72BDX 40 in. HD-Ready LCD Television
My tv must be almost 4 years old now, about 8 months ago every now and then the picture would just turn black. The sound could still be heard, but just a very dark screen. Turning the tv off and back on again would resolve the problem.But it's doing it all the time now,and driving me crazy.
May be the backlight is out, can you see a picture when shining a flashlight on the screen. if yes you have either a bad inverter power supply or bad screen (panel).
both are serious , also could be just a few bad capacitors on the power supply, if you want you can do a visual of the power board caps will appear swollen on top and are easy to solder in cost about $1 each
