Have you made sure the connections are secure on all ends? Did you turn off the breaker for the plug while the TV was still plugged in? If so when you switched it on it could have shorted it out and fired the board. Check the breaker in case it needs to be reset. And check the socket In case it is faulty.
The way I did it was download the combination file and flashed it with the modified odin and then it takes you to binary mode and you can access settings to turn off USB debugging. After you do that flash the stock rom of the same model of phone and then it's done.
