I am sure the tv is shot from the surge but you can check a few things. I would take the tv apart and test the power supply first. Look for obvious burn damage throughout the boards. If there is a blackened one (prob video board) then you can try to replace that. Don't worry about taking this apart and breaking it further. In this case it can only get better for you.

    Thank Jerry, I think I will give it a try and look for obvious damage with the fuse and capacitors.

    Hi Jerry, thanks for responding. I've looked for obvious damage (nothing). Shouldn't the fuse by the power supply be blown? I also have a Sony Home theater system that was blown as well as and LG Home Theater System. I need some help Bro. all my entertainment was blown at once. I'm a California Boy, never had this happen, is there anything you can suggest? Thanks I know time is valuable yours is appreciated...TLG...

    Sorry...haven't been on in awhile. Fuse is not always by the power supply. It is put wherever it can fit. Keep looking. I would also suggest a real surge suppressor which I can suggest if you are interested.

Hi
You may have a power supply problem with the unit. Have the unit checked for correct power voltage ratings on the PS. Or just replace the power supply

Testimonial: "Hi, Thanks for the response. Could you please tell me what would be the cost if i replace the Power Supply Unit."

SOURCE: sony bravia l42" LCD TV. No power. Green light on

7 blinks in the this series(KLV) means there is a short in the power supply board. The easiest way to fix this would be to swap out the board. I can find you a replacement if you want to try fixing this yourself.

try unplugging your t.v for a few minutes, then plug it back in. if it continues check your owners manual or google your issue. this might be the red flash of death. hopefully unplugging it works. good luck!

My sony bravia NSX-40GT1 is dead....no lights...nothing. (lightning strike) If I replace the P/S board will that get it up and running?

First things i would check are the powerpoint and then the fuses
a lightning strike at the powerpole may take out a fuse at the fuse box thus no power at the powerpoint,a power surge could take out the fuses on the powersupply board but check all fuses ,be sure to unplug the set from the wall first.
good luck.

Sony Bravia KDl-55EX720 Struck by lightning.Red light shines.Nothing else works.

Claim on your insurance. lightning strikes reach voltages higher than a PCB (printed Circuit Board ) can handle. most of the chips inside will probably be bits of burnt glass now.

I have a Sony Bravia LCD tv an it won't turn on at all the standby light is not even there I've tried turning on an off and leaving unplugged for an hour still nothing.? Help,

You either have a problem with your power supply board or main board. I would start with having the power supply fuse checked as well as the power supply board!

Your Sony Bravia KDL-46S5100 might have been affected and damaged by the lightning strike. You cannot fix it without the help of qualified technician. It must be brought to your nearest service center.
