Help? I knocked a SMT resistor off the board by accident, the value was 0.01MF, 50V. Surface Mount pisses me off, that thing was smaller than a crumb. I was unable to get it back on, then I lost it, so I bridged the two connections with solder. Could that be it? This was on the neck board.

That surface mount part is actually a capacitor rated at .01 uF @50 volts. You can replace it with a standard .01 uf cap rated with a voltage rating of at least 50 volts. When you bridged the connection, that created a short that could very well be causing your new problem. Maybe you'll get lucky and it didn't take anything else with it.
You're not the only one that gets PO'd at SMT devices. A great deal of consumer electronics is 95% (or more) SMT. The only economical way for repair is a new board. I recently repaired a newer JVC TV that had two open SMD resistors on the neck board. These resistors were, IMHO, too small for their task. I just took two through hole standard resistors and tacked them to the PC board and it worked fine. IMHO, SMT technology has no place in high voltage, high current, or high temperature applications.
