Sharp LC-32SB24U 32in LCD TV -- Power LED blinks green

Those 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.

What kind of TV is it? If it is rear projection, you may need a new lamp.

Its almost always caused by bad capacitors on the power board. You can get a repair kit or the replacement power supply board from www.tvrepairworld.com

How are the power and opc lights blinking? Do they blink simultaneously or does one blink then the other? How many time do they blink per second? Also have you had it fixed yet? and if so what was done? I had a similar problem with my set.

The green lights on a Sharp television indicate a problem. The number of blinks is a code. The television has gone into a coma in order to protect itself. You can force this television on by doing this. Unplug the television. Hold down the vol+ and channel down button on the television and while holding them down still plug the television in. This is a temporary way to view the television but the problem will get worse if not repaired. Should the television power on this way unplug it when you want to turn it off without pressing the power button at all.

Turn off/on couples times,power it well come back on stable,if not ur video board it dead.

power inverter board is dead.
need a new one.

This same thing happened to me, but not until I fiddled with all of my remotes, trying to see if it was an input issue, battery issue, etc. I finally unplugged the tv from the wall and plugged it back in. Nothing. Then I went to take 5 minute ****. When I finished, the Power & OPC lights were blinking, and out of sync. I pressed the power button at the top of my TV and got a picture.

Word.

Good Day, texxastam;

Do this:

1. UNPLUG TV
2. HOLD IN VOLUME DOWN &INPUT buttons on TV
3. Plug in the TV. (the TV will turn itself on).
4. A blue "K" should now be showing on the TV screen, release the buttons.
5. Press and release the VOLUME DOWN & CHANNEL DOWN buttons simultaneously on the TV. (A blue service menu will appear on the screen).
6. Using the remote, press the DOWN SELECT button once. (The highlighted line should read INDUSTRY INT (+CAUSE) OFF
7. Using the remote, press VOLUME UP once (OFF changes to ON).
8. Press ENTER. After a few seconds the screen turns green and shows - Industry INIT success - at the top of the screen.
