Check your fuses for the +100v , -100v circuits coming off the power supply board.

Quoted from DCSPORTSFAN:

I do not think I have seen the "fuses for the +100v , -100v circuits coming off the power supply board." are they on the board or inline somewhere else?

I meant you should check the fuse for the score displays. On my Firepower this is fuse F1 score displays. It is a 90v 0.25 amp slow blow. Double check your manual for GL and find that same fuse and test it with a meter.

deleted bad advice...

Test & replace some more of the components in the HV section of power supply. There's really not that much to the HV section.

Looking at the schematic, it's basically Q3, Q4, ZR4, C4, R6, etc.
