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)

SOURCE: Sharp LC-37HV4U not turning on

Thank you, psxpirate25!!!! It worked. I had to repeat it about 35 times. It came up in a factory setup firmware mode. I could see the video behind it. Pressing buttons on the remote only switched between the settings menus. I power cycled it a couple of times and had to do another 35 times. Finally it worked! Totally awesome!

Unfortunately not really, it is the video board of the LCD that has failed, it is a major repair to say the least. You can check with a local repair shop to estimate the repair, but it will be spendy :(. I'm so sorry about the bad news there, but that's definitely what it is. If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.
Thanks Tim

Display powers of with power up of AVC


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

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. :)

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.

Lcd sharp tv flashing green light


Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.

Sharp LC-37HV4U not turning on


hold down the input button and volume - while the MAIN POWER BUTTON IS OFF. Then turn on the main power button while those are held down, the light on the tv & avc box will turn green, then immediately let off the 2 buttons and press volume +. Next step is to repeat the process about 20-40 times & the TV WILL WORK!. I have read that this may have something to do with the energy star compliant commads that can changed through the serial port.
