The power light is an error code that tells me exactly what is wrong with the TV. Count how many times the POWER led flashes per second? (Dont worry about the OPC led)

1x per second (constant steady blink) = bad inverters/lamps
2x per second = bad power supply
3x per second = bad main board

If its 1x per second, try doing the factory initialization to get the TV back on to confirm a bad lamp/inverter.

Try doing the Factory Initialization (WARNING: THIS GIVES YOU ACCESS TO THE SERVICE MENU. DO NOT ADJUST ANYTHING IN THE SERVICE MENU OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS. IF YOU DECIDED TO ADJUST ANYTHING OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS, I WILL NOT BE RESPONSIBLE IF ANYTHING WRONG HAPPENS TO YOUR TV.)

1. unplug tv
2. press and hold at the same time “Vol –“ and “input” button on the TV set.
3. while holding those buttons, plug the tv back in
4. the tv should turn on by itself, keep holding the buttons until the letter “K” appears. Then let go.

Once the TV turns on, take a look at the screen. Does it flicker then shut off? Or do you hear a buzzing noise from the right edge of the TV? If so, then you have bad inverters or lamps. Once youre done, unplug the tv to get it out of the service menu.

If it is 2x per second or 3x per second, then those boards are just bad and they need to be replaced. There isnt anything you can do right now to fix it.

If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ Search the site by type in the "brand name" of your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

While the set is turned on, you need to hold the power button until the set shuts off and the led in the middle of the bottom flashes once. Then quickly release the power button and press the vol - and input buttons together along with the power button. Your TV should then turn on and should show you a blue box with the letter K. Now press the vol- and channel- buttons at the same time. You should now be in the service menu. With your remote arrow up until the top line says industry init. Arrow to the right and hit enter. Screen should turn green and say factory init success. I hope this helps you.

how many blinks does the red light give in a row? This would be an error code?

The problem for 7 blinks would be an Interface board. Apparently there is a glitch in the interface board that sends signals to the television. Basically the glitch shorts out the board and the t.v wont turn on and you will see the power light blink 7 times pause then 7 more. You can replace the board with a new one and update the software on the new interface board.


If is isn't 7, let me know and I will help you out with this

thanks

There is obviously something wrong with the set but the tech didn't catch it giving issues so wasn't able to fix it...I"d start by checking the power supply voltages if your able

Factory Reset Sharp Aquos LCD TV 3 ways to reset TVs Sharp TV fix review i understand some models need remote and other codes

It is an LCD panel failure, Require LCD assembly replacement and absolutely not economical .

If you bought it with a credit card that usually gives you a year of extended warranty so repairs would be no cost

I'm not sure if this is the same, but people were green no matter how i adjusted the tint, and lacked overall color. I doubled checked the component cables, taking each one out, and putting it back firmly,
Picture is back to normal. Easy fix.

According to SharpUSA the problem with the "Loss of Sync" error message is that (most probably) the cables (between the box and the display) are not connected properly (so remove and reconnect them carefully, on both units) or a cable is defective. 

Also, after you reconnect the cables try turning on the unit, if no success then depress the "clear" button on the external box (under the door on the front and on the bottom left and try turning on the TV again). 

It is, most likely, that the cables are not seated properly. Reseat the cables on both the display and the external box. 

Hopefully, this will clear the problem if still does not solves your problem just replace all the cables connected between .u can get the new cables at radioshack web site.just place an order they will provide you. thanks.

am not sure on size service manual doesnt say but there 2 1/2 long.

Use some other Pan Drive and checked some of HP & Sony Pan Drive will have problem
