Sharp Aquos LC-30HV4U LCD Screen will not turn on

Sharp Aquos LC-30HV4U shut off in the middle of a show and will not turn back on. The indicator light on the LCD screen that shows red when on standby and green when in use does not turn on. This model comes with an AVC box (this is where everything gets plugged in: Dvd, dish, PS3, etc) to reduce clutter if the tv is mounted, which is separate and still turns on fine. Is this a capacitor issue or a power supply issue? Please help. TV is not that old =( Thank you!

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.

The screen and the module both are showing red lights . The screen will not show a picture and I have tried to reset. Any options?


Press the VOL+ and Channel - button on the set and than the power button while holding the two buttons.
If the set starts then the fault is the error counter wich must be reset to 0. Max is 5 faults,if a sixth error is measured the set stops.

Sharp aquos has green and white vertical lines


You must contact a svc co. This is a upper or lower buffer board problem and possibly a control board. Nothing you have done wrong, it just happened.
