Power light comes on, no picture, then the opc lights flash and power light flashes, then just power ligh stays on, but no sound or picture

SOURCE: POWER AND OPC LIGHT BLINKING GREEN

The condition of your TV called power supply overcurrent shutdown that"s why you hear a click. The TV is going into a protection mode to prevent further circuit damage. That's why it will not turn on or not powering up. I would concentrate on the power supply section board. Bad regulation of the incoming voltage could caused this issue although,there is a capacitor across the incoming line and nuetral.Maybe its leak or dry up and cause the problems,change it out with one of identical rating . Although now you are getting into dangerous area,especially if you have no electronic experience background. It could be also be a loose ,crack or cold solder joint,a blown fuse,fusible links or other component .It could be one of several boards.Unfortunately the level of sophistication on these TV make it virtually impossible to diagnose them further without taking them apart and probing around with a multimeter and other tools.This TV is handy enough to take to a repair shop find a good one.You will probably have to pay $75 to $100....

Hope this may help you..

hey i have had the same problem but i unplugged the tv for awhile about a half hour and then plug your tv into a different wall outlet if you can and should work. It worked for me, i had it plugged into a surge protector then i unplugged it from there, let it sit of half hour then plugged into different wall outlet and worked. so try that and see if it works.

capacitor maybe? Mine was doing the same until I opened her up and discovered three blown capacitors.

WHEN FLAT SCREEN SHARP LCD IS ON .. BLIKNING ON BOTTOM OF SCREEN SAYS OPC

SOURCE: no picture no sound opc light and power light

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.
