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.

Blinking codes details of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

My Sharp tv remote will not turn on / off tv. It will turn on by the main power switch on tv but not by remote.

From page 8 of the manual:

The POWER indicator on the AQUOS television should light GREEN indicating you have power to the AQUOS television.

If the POWER indicator on the AQUOS television still does not light up, press TV POWER on the remote control to turn the power on.

IMPORTANT:
IF THE UNIT DOES NOT POWER ON - UNPLUG THE AQUOS TELEVISION FROM THE OUTLET AND REPEAT THE INSTALLATION STEPS.

IF YOU STILL ENCOUNTER NO POWER, PLEASE CONTACT US AT 1-800-BE-SHARP

I have a 42inch sharp aquos LCD tv and there is no power. The power button keeps blinking. There is no picture and sound. What is the fix to this problem.

Power problem are cause by many reasons, i.e Power supply circuit, Lamp driver circuit and most often the TV detects an error cause by power surges. To protect TV from further damage most LCD TV have protection circuit built internally. If this is the reason of your LCD TV not powering On, an error data must be reset back to zero.
To change data you will need to access the service mode and change the value of lamp error code to zero (0). Entering service mode requires a trained TV technician. Changing data can cause more problem to your television. If you are not qualified to service your television, please do not go to service menu codes. Moreover below are the process, pls do so at your own risk.
* Unplug the TV * Press and hold the {VOL -} + {CH+} buttons located on LCD TV unit (not in remote control) Note: If above didn't work, alternately use (VOL -) + (TV/AV input) buttons located on LCD TV unit (not in remote control) * While holding the above buttons, plug in the TV. * The TV will turn on with the "K" or "K123" appears om screen. * Use {CH+} {CH -} buttons to go and display the service menu. Note: If above didn't work, alternately use (VOL -) + (CH -) buttons. * Search for "LAMP ERROR menu" from the displayed service menu by using "up or Down cursor" from remote control, or alternatively use "CH - or CH+ to select "LAMP ERROR" * change it to zero (0) value, using {VOL+} or (VOL -) on remote control. * Turn the set off to exit the Service Menu.

I have a brand new Aquos 52" LED TV and I accidentally locked remote operation and THEN found out the front touch screen panel was broken. Any way to manually reset the TV or remote to gain access to...

While the set is turned on, you need to hold the power button until the set shuts off and the led in the middle of the bottom flashes once. Then quickly release the power button and press the vol - and input buttons together along with the power button. Your TV should then turn on and should show you a blue box with the letter K. Now press the vol- and channel- buttons at the same time. You should now be in the service menu. With your remote arrow up until the top line says industry init. Arrow to the right and hit enter. Screen should turn green and say factory init success. I hope this helps you.

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.
