I have a Sharp 60 inch ledtv (LC60LE835U). The power button flashes short/long. I used the reset code but have no picture or sound. I looked through the back panel and don't see any lights. I also used the flashlight test and can see video, but can not see any remote volume bars or menu operations. Any help is appreciated.

Try unplugging the unit and hold the volume up and channel down buttons down and plug the unit in. Let go of the buttons and the unit should come on up the service mode. There will be a small k on the screen. With the remote press the channel up button . 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. Use channel down to highlight that line and the 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. 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 .

You have to go into the sound setup menu and select which audio out you are using. Select either digital or fiber so the TV can direst the sound to the proper port.

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 stage 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, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

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 [email protected]. 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.
