[Motorola] Motorola R2001D display problems

[N0KQY]

Evening All,

Having an intermittant problem with my 2001d monitor. The CRT display
will intermittantly flash from a bright well focused display to a
ballooned, still focused, two times enlarged display centered as the
origional display was. Then it will flash back to a normal display
screen. But it will also flash to a full screen display that is fully
collored in, as the whole screed is shown with no lettering but not
enlarged. When this happens, the focus and intensity controls still
function as the normally do. 

Anyone have a direction or thoughts on this??


Thanks,

Gary  N0KQY
