1 Answer

Sharp TV won't turn back on! Help please?

Sharp aquos: lc-42d69u I was watching TV through my computer through an HDMI cable and suddenly the screen went static for a second and powered off. Tried unplugging it and still no luck. The power light is off as well. I was wondering if anyone had any ideas what may be wrong and how how to fix it. I am willing to take it apart and fix it but I'm not sure what to be looking for and what to replace. Thanks!

It sounds that the main power regulator board to your TV has damaged. Contact any service technician.

SOURCE: my Sharp Aquos lc-46d62u has audio but not video. Only a blue screen

If you are using a box of some kind remove it and the set from power for a while and then plug back to allow both to come on and reboot---blue screen usually means no signal seen..........check the other inputs on set with a dvd player etc.

It may not be an adjustment, it is possible to take a good photo or video and post it here which might indicate what is really wrong.

I have a Sharp Aquos # LC-45GD4U. It now suddenly turns off by itself and stays off until I turn it back on. This happens while watching live TV or playing back a recorded show. Ideas?


Check the ventilation fins on the back. Sometimes they get obstructed with dust and then heat builds up. The TV then shuts down to protect itself from overheating. You can use a blow dryer to blow it out.

Television is not recognizing HDMI inputs


there is a possibility that there might have been a power surge sent over hdmi into the hdmi board on the tv. if on your model the hdmi board is seperate from the sine board then youll have a cheap replacement if not its gonna cost you roughly 300-400 is my guess.
