I've tested all of the tubes inside the tv and they all tested good, so maybe its due for a recap?
Although I would of figured I would of gotten at least something...

Try using a different signal source, VCR or DTV convertor.
If I have trouble with a signal source, I try switching the RF out on the VCR, 3/4 switch, usually on the back.
The tuner might need cleaning, because of the poor storage conditions. The contacts seem to corrode more the when stored in a home.
