Tv shutting off

My tv is just keeps shutting off on it's own. the power and opc button is blinking. i can't get the tv to stay own. what is the problem? I have a LC-26DV10U 26" LCD Sharp - Started turning off by itself - has to be unplugged and sit for a few minutes before it will turn on. Has got progressively worse, now turns off right after you turn it on. Hesitant to spend $100+ for new power supply on a guess...Help!?

Its a problem with the Power boar or the Digital processing board.

Turn off the TV for 10-15 min. Unplug and replug the power connector.

Also try a different power source.

If it doesnt work then first get the power board checked. A minor repair is what it will take to resolve the issue. Contact www.bestbuy.com or any local tech shop.

Thanks

    This almost sounds like something is overheating. The key is that you say when you turn it off and back on it starts working but it fails quicker, and the audio never fails (meaning its probably not some automatic shutoff thats just set real short).

    If its new I think I'd just return it for exchange.

Hi palmer

Is the power light blinking any pattern and also what color is it as this will help narrow down exactly what the problem is which like you are thinking may be the power supply which is the most likely problem. Please let me know details about the light.

TV turns on screen comes up just fine but won't stay on. What does the power button blinking twice and the OPC button blinking 3 times mean?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

So when i turn on my sharp hd it turns off then the opc light comes on! Then the power light and opc light keep flashing!! Alls i want 4 it to work? Plz help


The television has gone into a coma. It is going to need to be serviced or replaced. The blinking code is a pattern. If you look at the power light and the opc light separately and independently, you can acquire the blinking pattern. Cover opc and look at power only. Note how many times it is blinking before it pauses. It might just blink steadily. Next cover power and look at opc alone. Note how many times it blinks before it pauses.

Depending on which model you have it might work if you leave the television unplugged overnight. The next day plug the television back in and wait for the blinking to start. Hold down the power button on the side of the television until the light stops blinking and turns red (usually right away). Let go. Press and release the power button once more and the light should turn orangish and then green. The television should turn on.

You can call Sharp and have a case file created and try and INIT with the customer service representative.

Tv shutting off


it sounds like it may be a capacitor problem and it may be linked to the electricity you receive adding a battery back up of sufficient quality will smooth out the electric current and also **** up the spikes from the power and light company. I have seen many aquas suffer from capacitor failure but it may be an expensive fix.
check your electric output and see if it can handle the load for this tv.

Just take it back, and if they will only do an exchange, test the new one before it leaves the store. If you get to change models, Google it with 'complaint' or 'repair' in the search before you take it. Under no circumstances let them try to fix it.

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

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

You can buy the parts online and fix if yourself!!
