Flat screen tv won't turn on

if this tv is still under warranty i would be filling a claim straight away this is almost always wither a hardware or firmware fault both of which if stock should be covered under warranty.

good luck.

I've had this problem on one of my sharp tv's.

Have someone help you as it's hard to reach around a large tv sometimes.

Unplug the tv. Hold down the volume down and Handel down button. Now, have the person plug in the power for you. Continue holding the buttons and you'll see the screen flash or turn on.

If that doesn't work, try holding just the power button and plugging it in. If that doesn't work, try all 3 buttons.

You'll see the red light flash green or stay green and turn on. You might hear the power supply click on or hear the buzz of the inverter.

If it doesn't work after a few tries, the backlight bulb might be bad. It's probably been on too many hours, and so, the backlight will burn out. It's not worth fixing (if you can find one) so just buy s new one. That, or the inverter is shot.

Newer LEDs do not have inverters so it'll never burn out totally. However, it is possible for a single bulb to burn out, in which you'll see a dark sport or shadow effect.

Sounds like corrupted firmware. A firmware update is necessary. Contact the authorized service center for Sharp.

If you bought it with a credit card that usually gives you a year of extended warranty so repairs would be no cost

I had the same problem and the power light was blinking a specific code (3 slow and 1 fast). I made a video on how I fixed it.

The TV you have has a 1 year warrantee. Call 1-800-237-4277 (1-800-BE-SHARP) for customer support.

Sounds like an impact to the screen. Screens can't be fixed.

This could be 1 of three things! 1-main lcd panel
2-y sustain module
3-z sustain module

This is something you cannot do yourself my friend.
