Possible errors in the main board , it can be due to failure of a solder joint in the set.
Remove the back panel and switch on the TV to work. when the fault appears then the main boarrd can be tapped lightly to see if there is any switch on of the picture. If so the fault is confirmed and you can continue further. Remove the power connection and solder.

It shuts off afer 5 seconds when powered on.


Does the unit output sound when powered on? If no sound can be heard, and you only hear a click after 5 sec. then your power circuit may have a faulty diode.

Sharp aquos 32" LCD tv - screen black (no picture) but have sound


Typically if you have a backlight and no video image it's going to be the T-Con board. We do know it's most likely not the powersupply board because the back light comes on. Could also possibly be the main board, but typically the T-con boards are cheaper and I'd say you got a 70% chance that's the issue. Good luck.

No picture or sound


If the screen displays VIDEO 1 then the set is in video 1 mode, looking for a signal on the video 1 input jacks. Press the TV/VIDEO button on the remote (or the set itself if it has it) and cycle around to the input you are actually using.
