SOURCE: tv wont turn

The blinking red light at the the front of the television is the "Diagnostic STANDBY/TIMER LED".
This little red light will blink 2, 4, or 5 times and then stay off for three-seconds. And blink again for 2, 4, or 5 times. This cycle repeats. The most common diagnostic code is the 4-blink code.

When the red LED blinks 4-times, it means one of two possible causes:
1) +13V is not supplied on the A-board. Or, 2) IC502 is faulty.

It is best to take this television set to a repair facility and ask that the +13V power supply be repaired.
The copper tracks and integrated circuit pads are very thin and delicate on the KV-24FV12 circuit board, and will easily lift off of the circuit board, if the incorrect desoldering tool is used. Unless one has a good quality PACE vacuum desoldering unit, one should not attempt to repair the television.

SOURCE: my sharp tv wont turn on

I don't know if you have this problem but I had a similar problem aswell. My TV remote and my universal remote wouldn't turn on or perform any of the funtions as they should. This is what I did to fix it: 1. unplug the TV from the power outlet. 2. take the batteries out of your TV remote. 3. press the power button on the TV remote, and then press every other single button one by one from left to right (as if you were reading a book). 4. plug the power cord back in the power outlet. 5. replace the batteries in your TV remote. 6. try turning on the TV using the factory remote.
These steps, as weird as they sound, worked just fine for me. My TV is now responding to my remote and my cable remote is able to control the TV again. No, I did not loose the universal (cable) remote's TV codes. FYI. the steps mentioned above were performed using the TV native remote (factory remote). Hope this will work out for you as well. And if you are wondering how I knew this would work, well I saw the same steps on another website (sorry I can't remember which website it was) and decided to give it a try before I took the TV back to BestBuy for warranty repair...which would have taken like two weeks.

SOURCE: my tv wont power on

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

Also ensure 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.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

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

1The internal circuits are jammed because of electrostatic chargesaccumulating on capacitors, or because of a wrong voltage read by themain chip on your monitor controller board. this started the protectioncircuit.

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


If you are in situation one, then theTV 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.

Common faults that can occurr are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing statebecause of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

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.

Have a sharp aquos Quattro 70 " that won't come on. Power light on front is flashing a quick flash then a little longer flash. Any ideas?


We call that one fast and one slow. The only way to know the cause is going into the service menu if possible. To do that you need to "force" the TV on. These are things a repair shop should do. Going into the service menu without knowledge could permanently damage the TV.

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.

I've a Sharp Aquos 32'' tv


The flashes are an error code. Count them till they repeat. Get a service manual and look up the error code. Some error codes prevent the set from powering up to prevent more damage. You can reset the code for troubleshooting. Repair as required.

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)
