Tv went off won't come back on

That tells me there is a bigger problem than that. I have several TVs in my house, none of which have ever been affected by static electricity before.

You most likely have a circuit board that has failed. Read about that at the link I will provide. TV Boards Buying Guide

try switching on tv point remote at the tv pressing the menu/exit button and holding for 10/20 seconds hope this works for you

This sounds like a common problem on these TVs. Try a factory reset:

1. Press and hold "Menu" and "Channel+" on the TV. (do not use the remote)
2. Using the other hand, press the Power button.
3. A small screen should appear in the top left part of the screen.
4. Using the remote, select "Memory Recall" and Enter.
5. Power off and reboot the TV and Computer.
6. Run channel auto-scan to regain the picture.

Most likely your TV's power supply was damaged with the power surge. You will need to take it to a repair place and have the supply checked out and find out the cost versus the value of the TV. I hope this helps.

Hello!
First move: unplug your broadcast provider's box, wait for a minute, then plug it back into power source. I mean: leave all the connections intact, just unplug from power source. It might be just power cord or power adapter. If that's not the case, please do the same with TV. Unplug it from wall outlet, wait a minute, plug it back in. It's a next step, if your "box" won't take care of the problem. If that won't take care of the issue, refer to owner's manual for "reset" procedure. Worst case scenario: you might need to replace main board inside or your TV.
good luck,
Thanks,

the problem was there's a cold solder on the power supply or in the raster circuit. Look for lose contact in the PCB board it might gonna work or check your plug might lose wiring. You need soldering to do this job.

Ur Main Fuses in the circuits breaker box must be to be restart it back.Turn off/on all the fuses on the main circuits breaker box to all the fuses in the box of the box to restart.All ur electical power outlets should work again.If not those power plug in outlets are shorted and dead must have to be replaced.
