Hi,

I have this one, Doesn't respond to mechanical prodding, very
intermittent.

The fault is described as a image gradually moving up and to the left
in diagonal direction (45 deg). The convergence drifts apart as pic
moves like rotating a portable 3 tube projector.

Checked the metal box (convergence generator) for bad SMD cap, solder
connections but I'm still stumped.

It looks like one of convergence voltage is drifting? Is the +
voltage for the left & top and - voltage for right & bottom? If so,
Would that one of - voltage intermittently drifting away? It didn't
look like convergence was distorting, it was moving together as one.

Cheers, Wizard
