NEC DM-2710 Professional Video Monitor Repair

[zeno]

This set will have a switching supply.
The flyback ( FBT ) is probably good. Normally they short
& no HV will come up or it will go into overcurrent SD or self destruct.
NEC monitor switchers were a large module very well shielded.
A look inside may turn up more bad electrolytics.
If its marked on the PCB you can look for the HV B+ supply & see if
it goes above spec ( typicaly abt 120 VDC ) before SD.

good luck
