Check whether its back-light is working. If not, check and replace the back-light inverter board. If you wish to get some details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up older posts.

I unplugged the TV and held the buttons down and it continued to flash. I continued to hold down the two buttons and replugged it in again and it worked. TV back up and working.

Unplugged it. After looking for a new tv online I decided to try getting it to work. So, plugged it back in and held down the power button, a red light came on, held down the power button again and an orange light came on, held down power button again and green light came on and tv powered on. This was simply a case of trial and success!

unplug, hold power button, plug in. If that doesn't work, unplug all the HDMI cables, unplug the power, hold power button, plug back in.

Our sharp LC-37D6U does not turn on. The opc/dl light keeps flashing green X3 then every second or so. and the blue power button flashes also. What might we have to do to solve the problem? thank you


The main tv Tuner signal board it is dead or it have problems,but tv still usable.Tries push the remote power switch off/on again everytimes OPC/Power LEDS lights flashes.Have to do this maybe 3 or 4 times for the tv to have a lite up LCD screen panel backlight to make the tv Tuner signal board to work again,for the tv to work.If still have same problems after 3 or 4 times power switch pushes off/on still have OPC/Power LEDS lights flashes.Mean the main tv Tuner signal board it is dead and can not be trying to save it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish tv Tuner signal board for the replacement.This solution 100% will work,if ur tv main Tuner signal board still have life left in it.I do this every few days out of a week for my 46" Sharp Aquo LCD tv set,tv it work all the times.

Sharp AQUOS LC-52D62U LCD TV


Sharp lcd screens are very easly damaged especially the larger screens,this could be at fault even though it looks ok,try shinning a light on the screen and checking every inch,could be the internal screen that has damage hence why not powering up.
Failing that it sounds like an internal short.
