If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

SOURCE: Sharp 52" Aquos LCD Will Not Turn ON-Blinking LEDs

I had a similar problem. Fleeting video, then audio only for few seconds and then nothing except the green power LED blinking on and off.
I changed the power inverter board, backlight inverter boards and power supply board but still the problem is not gone.

Just 18 month old TV and out of warranty.

60" sharp aquos power indicator is flashing one short flash and one long flash and keeps repeating the sequence


POWER LIGHT FLASHES ONE SHORT AND ONE LONG FLASH.
What is the problem? THE PROBLEM IS THAT ONE OF THE LED's STRIPS IS BAD!

SHARP AQUOS LC60LE810UN RESET INSTRUCTIONS

1)Plug in TV to electric current First then wait until LED start flashing.
2)Press Volume DOWN [ - ] HOLD BUTTON.
3)Press Channel UP [ ^ ] HOLD BUTTON.
4)Press Power [ (') ] HOLD ALL three buttons until LED stops flashing and then release.

    ·This will reset the TV in order to fix the problem.
    ·THE FIX IS TO REPLACE ONE OF THE LED's. You need to open the back of the TV and you will also need to remove the front cover and panel to get to the LEDs. The TV will need to be placed facedown and on the backside. This is a 2 person job to turn the TV on its sides. Be careful with the white computer connectors (wide white strip) at the base of the TV where the TV stand sits. You will need to disconnect this in order to get to the LED's.
    Once you have the LED's exposed, you will need to unplug one by one by placing the new strip next to it until the unit turns on. You will have to use the RESET procedure above if the Power lite flashes. The Power lite MUST BE ON SOLID - no blinking in order to test the strips. The LED's will flash, but still one of them will be burned. Even if you stare and all the strip light-up, you will still need to check one-by-one!
    Once the TV lights up, your face will also light up with joy! Put everything back together and you are set. If you need the complete instructions which come from Sharp as to how to disassemble the unit, please send me an e-mail to LGTR61@YAHOO.ES. Please note I don't check this address daily, so a few days wait may take for you to receive the instructions.

    Where can you buy the LED's - try searching Yahoo.com or Google.com for resellers.

Sharp Aquos LC-52D64U Won't Turn On


I have fixed many sharp lcd tv's with a reset. If one appears to have no defects like bad capacitors, fried inverters, broken panel, ect. and the power light is flashing steady or not on at all a reset may help. There is a lot of bad information regarding the procedure though. The correct procedure is to unplug the tv, hold volume down and channel up at the same time and plug it in. Release those buttons then push the power button. Did it start? Great! I have no idea why so many seem to need this. If there truly is a problem this will only work temporarily or even momentarily but many will be fixed for good.

No POWER


How many times does the POWER led flash per second? (Dont worry about the OPC).

1x (steady constant blink) = Lamps or inverters
2x = Power Supply
3x = Main Unit

If i am reading it correctly, looks like the POWER led is flashing 2x, which means it is a power supply failure. Either way, your TV needs to have a board replaced, there isn't anything you can do to fix it yourself. Try locating your local sharp authorized service center to repair your TV (1-800-237-4277)
