Re: tv wont turn on
The surge most likely shorted the horizontal output transistor, and with that being shorted, it causes the power supply to "sing" from the increased load it is seeing. Unfortunately, it would probably cost near $100 to repair unless you were able to do it yourself.

There might be a failure on the power supply or horizontal section of the TV even if you see some light inside the TV. Some of the voltages could be missing and that is why the TV fails to power up.
If you know how to use a multimeter, you could check all the fuses from your power supply.
Unplug your TV from the main AC line if you intend to do it yourself.
You will know how much you can do or it might safer to contact a tech.

When u try it as a tv no picture,but does it have sound?Than ur LCD inverter board it dead.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish LCD inverter boad for the replacement.It a long board in shape.
The zapping noises are coming from the flyback transformer which is also why you do not have a picture. JVC discontinued this model so it is a good chance there are no parts available to fix it. You would be better off buying a new tv.
Does the standby light flash in a set pattern? Some tv have a error code system which pinpoints the fault by flashing the standby light a certain number of times. Other than that my best guess would be a fault on the power supply or a fuse blown internally. Good luck.
If you were watching the set and it went off bt itself is not likely is in any sleep mode,you have already tried unplugin the unit that did not work,The set needs service to diagnose what happened,I am sure is nothing you could have prevented,it just failed by itself.Is lees expensive if take the set to a servicer for an estimate.
