Sharp Aquos LC 42DH77: Inverter, Backlight, Power and ...

www.normsweb.com/tektips/42dh77.shtml

Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

push and hold the power button, i did yhat to mine and it now works,also if it comes on reset the tv

Common problems on Sharp LCD tvs as tv it is agings,tv Power LED and OPC LED,LEDS lights flashes happen to mine Sharp tv many times and i had it two years,do this many times,tries to turn on the tv.By trying pushes the power button the remote again if OPC LED and power LED,LEDS lights flashes together.Everytimes the OPC LED and power LED lights flashes,just push the power switch on the tv remote and wait for the tv main Tuner signal board to kick in the backlight to light up tv to work.Have to do this like three or four times before the power supply board to kick it in to make Tuner signal to work.If u require to this more than 5 or 6 times the main tv Tuner signal board it is shorting out and beyond trying to kick in by the power supply board.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish tv Tuner signal board for the replacement.

sounds like u have a bad mainboard.

power supply problem this can be done by a professional tv repair

The power supply board has been defected. Replace it with a new one.

try accessing tv through the remote control.

THIS BRAND OF TV IS NOT REALLY RELIABLE AS IT IS ECONOMICAL YOU SEEM TO HAVE A POWER SUPPLY PROBLEM MOST LIKELY A POWER CONTROL BOARD ISSUE .

IT WILL BE MORE ECONOMICAL TO PURCHASE A BETTER BRAND NAME TV AS THE INSIGNIA BRAND PRODUCT IS ECONOMICAL PARTS ARENT AVAILABLE.
