The tv is two years old, still in great shape. Last night while vacuuming I hit the power strip the TV is plugged into, this is an old power strip in which I had minor problems with such as if the cord plugged into the middle slot would be moved or hit in the wrong way whatever was plugged into it would shut off. This happened and it was no big deal, i would just have to position it back into place so it would work, but now when i turn on the tv i have no cable input, cannot change video channels like to "S-video" or "Input". All of the menus and remote still works, even the time and favorites channels are saved on the Tv. All connections are fine, the cable works and have tried the Tv in different rooms but still the same results, could this have been a problem from a possible power surge?
