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.
The fault is with its main power supply regulator section itself. One or more voltage rail is missing. Your TV need a through checkup. Seek tech assistance.
I have a sony bravia kdl 40v 5100 for less than two years and i did not purchased an extended warranty and now my tv is down.
I have no picture, no sound just a black screen when i turn the power on, the power (green) light is lite up and the tv turns off by itself for like less than 30 seconds. I have tried to press as many buttons on the remote control and on the side of the TV to get any message but nothing seem to happen. Any suggestions and solutions? Thanks
$145 to come out and diagnose the problems it is a ripp off.The tv have solid power light to the tv.Useally 90% of the times is it the tv Tuner signal board is causes and the problems,that the board,where the incomming broadcasting signal cable plug into it.U have some basic machanicals skills like take things aparts and putting it back together again.$145 bucks u can buy a refurbish tv Tnuer signal to replace it ur self.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.
You may have a case of a bad signal board. The clue was that your power button on the tv and remote are the only ones functioning. If the tv is still under warraty, call the service number to get help!
Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.
To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).
try some of the solutions on this link hope one will work for you.
