Went in to turn on the games and I noticed that the florescent tube in the SST backbox was off. Put in one from a working game and no dice. Took the SST one and put it in another game and it worked, so the light is good. Then noticed that the led for the 20v on the i/o driver board was out. Played a quick game to see if anything else had mysteriously broken over the night. Noticed the flashers were all out too.
What I have checked.
F7 out of the board, okay.
Cracked solder joints on J6, okay
No burnt or connector on J17 from xformer.
Tips, resistors and glass diodes for flashlamps, okay
Resistor 216, seems like it has been getting hot, but is still in specs.
Readings on BR2 based on Pinwiki's testing pics.
1. .438
2. .432
3. .431
4. .443
Thought it was just a fuse or a bad BR2, but now not so sure. Anyone have something else I should try. Tired of looking at it and need a "new" set of eyes to help me out.
Thanks for any suggestions.
