Sounds like something is drifting in the oscillator or sync separator circuits, possibly a resistor. Freeze spray is good, but you can sometimes find bad resistors by heating them up with a soldering iron, don't cook them, just a bit of heat to see if they cause the sync to go crazy.
If the Sams has a Horizontal setup procedure do that first.
Did you test the picture tube? Dark washed out picture could be a bad CRT but could also be something else in the video circuit.
Did you adjust the Ion Trap on the CRT for maximum brightness?
