The subject unit has no high voltage but it pulsates when I

try to turn it on. Does anyone know where I could get a

schematic and parts. Will really appreciated any and all

inputs. Willy

I have the exact symptom and need a schematic.

Plan is to disable monitor/high voltage and use external monitor.

Excellent idea DML, as long as the output of the flyback only

provides voltage for vertical deflection and nothing else..

Thank you very much for your response Willy
