Looks like +24V and +15V rail are dead or shorted, from LEDs in 2th pic.

Probably a problem on the power supply card, like old electrolytic capacitors. Or a short on one of the cards.

Check fuses first, on NSV card.

Then try pulling all cards except NSV card and see wether +24V and +15V rails come back to life. If they remain dead, it's likely a power sopply problem on NSV. Else it's a short on a card. If so, proceed to insert cards until you find the card(s) that short the rail.

Then you can search for short with a high resolution (many digits) multimeter on that card and hope that it's not some programmable logic chip (PAL/GAL and friends).
