The Tv clicks when plugged in, once the power is pushed the power light is a solid green. The Backlight powers on then off, then the power light only pulses green. What would this problem be and how will i be able to fix it myself.
I just repaired this LCD tv exact same model.
symptoms- when the tv turns on, all I get is a black screen with blinking green light. No other error codes. It was crazy frustrating trouble shooting this. I measured the transformers on the master and slave inverter board with a multi meter. The resistance should be 1.31 k ohms. All but one measured within the specs except one. I get an OL reading. I took a chance to order this part on eBay for 13 dollars. After soldering it, the resistance for all of the transformers were back to specs. The tv powered on and stayed on. Works good as new. If anyone has the this similar issue I would advice testing the mini transformers on your master and slave inverter board. My email is [email protected] for help.

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..

Ur Tuner signal board have problems or dead.Ur power LED light indicator stable for a few mins before the power LED light,and the OPC LED light indicators flashes?After the POWER light and OPC light indicators flashes,just push the power button again for the power recycles again.Probally have to pushes the power button 3 or 4 for power light and opc light indicators flashes,the LCD backlght will lght up and work.Sharp tv have this problems alot,very common in Sharp LCD tvs.

It may be detecting short circuits in the power supply or in the backlight inverter board, try disconnecting the power cable to the backlight inverter board to see it you can get it to come on without the pictures.
