I receintly fixed a Wyse 60 I bought at auction. The problem was a shorted diode in the grid supply for the CRT. The shorted diode caused excessive current in the flyback transformer and power transistor. These componants might have failed if the unit were left on long enough to cause thermal problems. Fortunatly in my unit they were still OK. Do you suppose these terminals have multiple common failure modes? Ken (No I don't have a schematic either) Burgess
