20 Most Recent Sharp Aquos LC-45GD4U 45 in. LCD HDTV Questions & Answers

i had the same problem in a sharp tv 32". on the remote control there was a view mode button, i changed the mode and the pc input label in the left upper corner gone

The power light is an error code that tells me exactly what is wrong with the TV. Count how many times the POWER led flashes per second? (Dont worry about the OPC led)

1x per second (constant steady blink) = bad inverters/lamps
2x per second = bad power supply
3x per second = bad main board

If its 1x per second, try doing the factory initialization to get the TV back on to confirm a bad lamp/inverter.

Try doing the Factory Initialization (WARNING: THIS GIVES YOU ACCESS TO THE SERVICE MENU. DO NOT ADJUST ANYTHING IN THE SERVICE MENU OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS. IF YOU DECIDED TO ADJUST ANYTHING OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS, I WILL NOT BE RESPONSIBLE IF ANYTHING WRONG HAPPENS TO YOUR TV.)

1. unplug tv
2. press and hold at the same time “Vol –“ and “input” button on the TV set.
3. while holding those buttons, plug the tv back in
4. the tv should turn on by itself, keep holding the buttons until the letter “K” appears. Then let go.

Once the TV turns on, take a look at the screen. Does it flicker then shut off? Or do you hear a buzzing noise from the right edge of the TV? If so, then you have bad inverters or lamps. Once youre done, unplug the tv to get it out of the service menu.

If it is 2x per second or 3x per second, then those boards are just bad and they need to be replaced. There isnt anything you can do right now to fix it.

Does your remote for the dish have an aspect ratio setting on it?...if it does change it to normal

Factory Default Reset:

- Unplug the TV and count to 10 slowly.
- Hold down the power button on the TV (not the remote.)
- Plug in the TV while holding power button.
- Count to 10 and release the power button.
- Turn it on and hope for the best.

Another way to verify if the remote is working is use your phone or camera to look at the IR eye of the remote while pressing a button you will be able to see a red light everytime you push the buttons to make sure the remote isnt just faulty.
