Awe man...

This is for the TV in my sig.

Every once in a while it looses horizontal hold.. Vertical seems fine, but the horizontal is completely lost.

Now here's the problem, I have recently been falling asleep in bed with this TV on, only to wake up in the morning with it still on.

Is it possible a tube is failing, or possibly something like a Capacitor? Smacking it on the side DOES cure it for another few days. So it seems like something loose, but all physical wires and tubes, seem to be secure. I even sanded the tubes pins, the electrical device that is not soldered or screwed down.
