When we have had this problem with our VR260's it could be cleared up
(to some degree) by adjusting the pots on the Deflection module.
Access could be gained by taking the cover off the monitor (four hex
screws in the back) and then sticking a long thin screwdriver down the
appropriate holes along the top of the monitor (they are labeled).
I've got to believe that something along these lines has been provided
on the VR262, although a quick look through the plastic case on mine
shows that the access holes are not in the same place.  Using this
method we've been able to reduce the distortion on the tubes, although
it never goes away completely.  I'm surprised your DEC rep didn't do
this before replacing the monitor.
