SOURCE: 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)

Unplug the unit for 1 minute, replug and try again. If it doesn't work the power supply is faulted and it needs professional service.

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!

SOURCE: Sharp LC-26D43U Power light flashes and unit won't turn on?

It's a power supply related problem. When it turns itself off, this it called protection mode. The TV automatically turns off to protect other parts form being damaged.
The most common problem is the Power Supply Unit or the Backlight Inverter Board.
You may have to take the TV to a repair shop to find out which one is bad. Paying a repair shop to replace the board for you maybe more than the TV is worth. If you let them diagnose it and you replace the bad circuit board yourself, it would be cheaper.

Here's a place I use to get parts for TVs:

The problem is the repair shop may charge you double or three times of what the part costs at the web site link above. Then, plus labor. I just want to save you money. :)

You need a remote, but just try disconnecting it from the mains. That might get rid of the lock symbol. The blue hue is a fault and you need a television engineer or a new television.

Why tv sharp lc-80le632u when its starts it appear this blinking error "Power supply error 2 D+3.3V error"


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.

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.

Sharp model lc-20sh1u won't turn on, just makes a clicking sound and indicator light flashes red.


The clicking sound may be a power relay coming on and then off--problem indicates a trouble in the main power supply.

The main tv Tuner signal board it is dead or it have problems,but tv still usable.Tries push the remote power switch off/on again everytimes OPC/Power LEDS lights flashes.Have to do this maybe 3 or 4 times for the tv to have a lite up LCD screen panel backlight to make the tv Tuner signal board to work again,for the tv to work.If still have same problems after 3 or 4 times power switch pushes off/on still have OPC/Power LEDS lights flashes.Mean the main tv Tuner signal board it is dead and can not be trying to save it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish tv Tuner signal board for the replacement.This solution 100% will work,if ur tv main Tuner signal board still have life left in it.I do this every few days out of a week for my 46" Sharp Aquo LCD tv set,tv it work all the times.

You either have broken power board or main board. Power board - blinking 2 per second, main board 3 times per second. In an case it has to be fixed by a technician.
