 I also had this same _EXACT_ problem happen to me in my commercial defenders
arcade game.  The focus knob has no effect now. I tried shorting the pot, 
opening it, still no effect.  My focus knob is mounted on the high voltage
supply, so I assumed that the high voltage supply was trashed. I took the thing
outm and haven't gotten around to getting another one, so I will be interested
in hearing anyone elses comments on these strange happenings.  If no one else
answers you, try replacing the HV supply like I am, maybe it will work!
