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.
