Put it back to the mid point of it's adjustment range.
If the V hold won't stop the picture rolling at some point in its adjustment range then the circuit that it affects has drifted out of tolerance. The defective parts in that circuit need to be replaced..

This sounds like one of the 9 volt regulators on the small signal board is going bad, supplying less than 8 volts. I have seen this is several of those sets. The IC needs to be replaced and if you do not have experience in servicing projection TV's then I suggest letting a qualified tech handle it for you.

Good Day, Maybeitstime:
Joe the cheapest way is to repair it yourself and this is what you need to do:
VERTICAL JITTER/HORZ UNSTABLE-CHECK 'GE' CONNECTOR PIN 5 FOR 1VPP Y SIGNAL INTO PIP PCB THEN CHECK 'GE' CONNECTOR PIN 11 FOR 1VPP Y SIGNAL FROM PIP PCB. IF SIGNAL AT PIN 5 IS GOOD AND PIN 11 IS CLIPPED OR REDUCED. CHECK ALL ELECTROLYTIC's (I.E.C7001, C7014, C7026, C7036) AND ALL CONNECTING TRACES TO THESE CAPS FOR CONTINUITY 2. HORIZONTAL TEARING, VERTICAL JITTER. SIGNAL RELATED CONDITION. APPLY FOLLOWING CIRCUIT CHANGES ON PCB-SIGNAL: A. REPLACE R2K8 WITH A 1K RESISTOR (BASE OF Q2B2). B. REPLACE R2K3 WITH A 47 OHM RESISTOR (IC201 PIN 50). C. ADD A 100PF CAPACITOR FROM BASE OF Q2B2 TO JUNCTION OF R2L0 AND R2K6 (GROUND).
As you can see this might be over you head but for a 1994 model you did get 14 years of watching TV enjoyment. 'Might think about replacement.
Good Luck, big IRISH.

My Mitsubishi Model VS-60705 did the same thing a couple of years ago...A TV repair facility replaced the Video card. Any repair facility facility that works on rear-projection TV's should be able to repair your set.
