Mine is flashing the power light and opc light sometimes. It takes anywhere between 1 minute and 10 minutes of powering on and off for it to finally work. I took the back off in hopes to see a popped cap or two but there is not evidence of failure. Has anyone got this fixed and if so how so I can give it a shot.
It sounds like you have some capacitors that have gone bad or changed value. The place to look is in the power supply boards. Notice the top of the caps have an indented X or V which is really a vent. If the cap over heats it will bubble out a brown residue on top of the cap. The top of the cap is supposed to be flat, if it's not flat but has a dome, replace it. You have to take the caps out of circuit to properly check them with a capacitance meter. Also bad solder joints on the power supply boards will give you these symptoms. Hair line cracks in solder will separate when cold but will expand and connect when warm. That's why it may start working after it's on for awhile.

Power and OPC LED lights flashes?Common on Sharp LCD tv.Tv is still useable.Tv have Tuner signal board problems.Every times Power and OPC LED lights flashes.Just push the remote power button again and wait.Sometimes Power and OPC LED light will flashes require push power again wait again Power and OPC will flashes two or three time push power button and wait.Must do this two or three time before the backlight will light up and tv work.
This tv still under warrenty?Yes take ur warrenty repair.This problems very common on Sharp LCD tvs.I have one too.This tv have a Tuner signal board problems.But this tv still use able.Just push power button again after the POWER and OPC flashes.POWER and OPC some will flashes again and wait just push the power button again and wait.Sometimes have to push power buttons and wait power button push out of three or four times power button push POWER and OPC flashes.Than tv will work again.
I have a Sharp LCD 46 in.tv do this often.Yes,it is.This problems,the tv Tuner signal board have problem,but the tv is still useable.The POWER and OPC light indications flashes.Just push the power switch again,wait see tv turn,not POWER and OPC flashes again,push the power switch agian and wait.Have to do this like 3 or 4 times sometimes,than the tv backlight will come on,tv will work.Don't know but,if u require to pushing power button more 10 or 12 times,the tv Tuner signal board don't take an turn on the tv backlight get the tv to work.The Tuner signal board is dead,time to replaced the tv Tuner signal board.
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 is very common in sharp tvs.U turn it on.U get power on light stable right?U hear a click,one or twice,sometime tv is good right?Sometime POWER light and OPC light flashes?Push the power button on/off couples times will work, picture will come on.If keep trying off/on couples time after POWER and OPC flashes,don't ever stop and never get backlight and picture.Ur Video backlight board is dead must replaced.
Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu. I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!
