OP, lightning is a strange phenomenon, and problems like you are describing can happen when there is a remote ground (think cable or satellite cable) connected to the equipment, in this case, the connection was probably through the TV set, which apparently survived. I am guessing, there was a surge, it was capacitively coupled through the power supply or the cable to an internal component that was tied to both and failed.
