Osborne Vixen - Zenith 7" display t-shooting issues

[Chuck Guzis]

I've got the service manual to the Zenith DT2 display (includes a linear 
PSU); dated 1979 and identified as part of the D12 series of monitors.

The HOT is a Zenith 121-1039, which, according to NTE is replaceable by 
NTE 379.

Dunno if that helps or not.
