			=== Resetting the TV ===

			http://www.fixya.com/support/t17617780-60_sharp_aquos_power_indicator_flashing

			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 LGTR61@YAHOO.ES. 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.

			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)
