Does anyone have schematics or suggestions for repairing a Tek P6563A scope probe? The problem is the signal line has only a 390 ohm resistance to the shield as measured with a DMM.

If you have a x1 probe and it's not connect to the scope (or any other piece of test equipment) then the resistance should be near infinity.
