I get no picture and seems like no high voltage.
Spot killer comes on if I unplug edge connector, but is off when I use a known working board (game plays blind)
Fuse F102 blows it's a slow blow 1 A


What I've done so far. Cap kit. New 2N3716 and 2N3792 transistors. Replaced HV Diode. Reflowed connector pins. Replaced all fuses.

I've read about testing the D100 but don't exactly know how thats done.
Any Help?
 
tested D100 and it seems good.

tested the brightness, and contrast pots and get either an open or an intermitent resistance on the brightness level pot.
 
Update:
Our very own local guru (Atari Jim) had a go at this and spotted a cap in the high voltage section I had reversed (damn). Then he re-pinned the connectors and it's running perfectly. :)
