Question about Sharp Aquos LC-45GD4U 45 in. LCD HDTV

1 Answer

Sharp LC-30HV4U You seem to have knowledge on the Sharp LCD's. I have had intermittant problems getting my flatscreen to turn on, then when it decides to turn on I can watch it for awhile then it turns off by itself. Usually after sitting for awhile, sometimes days, I can get it to turn back on however it will turn itself off again. I have been told it may be a board of some kind but can't get any definate answers. Any help would be greatky apprceiated. Thanks, Al G

I HAVE A LCD TV MODEL# LC-30HV4U SERIAL #402334728 WON'T TURN ON


Did you leave it on for a long time? Did you happen to put a blanket over it to play music on it while sleeping? If a TV won't turn on, it can be due to overheating, which subsequently fries components.
