You need to get it repaired properly at some repair centre nearby.
Otherwise, your iphone got powered on bcoz it was provided with a power supply on your PC. But the PC wont be able to read the phone bcoz the chip got damaged in the process.
I think its the best option available.

umm... please check whether you have any wifi or other cellular devices which emit RF / wireless signals, located near the TV. Within a proximity of 4-5 feet. If so, try relocating such device 7-8 feet away from the TV.
Also check for faulty cables or loose connector socket.
I hope your issue...
