The main tv Tuner signal board have problems or it is dying or might be dead already.But sometimes this tv will still work and can be used,i have the same tv have the same problems it work for me all the times.By doing this process.Everytimes Power and OPC lights blinks.Just push the remote power switch again for tv to repower the tv power and OPC lights again,have go thought this process pushing power remote switch again have to do this like 3 or 4 times sometimes before the tv to work.Tries websites like Shopjimmy.com or Ebay.com to buy a whole new refurbish main tv Tuner signal board for the replacement.

Sharp LCD tv tend to have trouble with power LED light and OPC light flashes together?That what u having?Yes,this tv is having trouble with it tv Tuner signal board itself.This tv is still useable.By pushing the power button again and wait for awhile than the backlight will come on and work,Sometime Power and OPC LED lights flashes quit awhile.Just have to push power button and wait have to do this 3 or 4 times,before tv backlight to come to work.I have a Sharp Aquo my self 46' do this most of the times.
Ok This is how to troubleshoot the TV, there are lights on the front and you are mainly concerned with two of these lights (the power light and the OPC light). I) If non of the lights come on then this is a AC Power failure (There is a loose connection or you need to check the Power/Inverter unit or the Main unit) II) If the power light is blinking at a rate of one blink per min and the OPC light is off (then there is a CCFL backlight problem) III) If the power light is blinking at a rate of two times per min and the OPC light blinks at a rate of one time per min (13V/UR10V failure you need to check the Power/inverter board or the main board). IV) If the power light is blinking at a rate or two times per min and the OPC light blinks at a rate of two times per min (3.3V Main Failure check power/inverter board or Main board). V) If the power light is blinking at a rate or two times per min and the OPC light blinks at a rate of three times per min (UR6V failure check power/inverter board or Main board). VI) If the power light is blinking at a rate or two times per min and the OPC light blinks at a rate of Five times per min (Panel 5V failure check LCD control unit or control panel).
I have this model of the sharp tv.Happen to me very often the Power and OPC LED light indicators blink continueosly.Not the power supply board,it the Tuner board that take in the comming broscast signal that have the problems.You still can used this tv.Push the power button sometime the tv it will work right away.Not,each time POWER and OPC lights continueosly blinks.Just push the power button again each time the POWER and the OPC continueosly blinks.Just have push power button again about 4 times each time Power and OPC blinks recycles,it will finally show the backlight and picture come on.My guest,if u do this by pushing power button to recycles about 10-12 times each time the POWER and OPC blinks it time to change the Tuner signal board.
This problems very common on Sharp Tv.Do ur tv LED power light turn on solid first.Few mins,than LED,OPC flahes.Power LED,OPC flashes,push power button again,do this at leat 5 or 6 times somtimes the backlight will come back on and work.The power LED,OPC light flashes,turn off/on more than 5 or 6 times don't work.Ur Tuner signal board is dead,must replaced.
