I have a Ms. Pac that when I got it had damage to the neck of the tube. However the neckboard and monitor chassis, were, I believe, OK. When you powered up the machine with the neckboard unattached to the tube, you would hear a "buzz" sound, which I figured meant it was getting power.
I initially tried to repair the original tube by reattaching the white plastic piece to the base of it that slips over the pins (it had come off somehow by the prior owner's work). I hooked up the neckboard to the tube and on power up, could see a blue spark-like light, different from the orange you would see with a tube that is OK. After about 10 secs the spark-like light stopped.
I have since gotten a newer tube, installed it and hooked everything up. But this time, I am getting nothing at all. Does it sound like I damaged the monitor chassis by hooking it up to the broken tube? Here are some other things I have already checked:
1. there is 125V AC getting to the monitor chassis, checked that with my multimeter
2. The fuse that is lowest on the chassis board when the board is mounted in place is OK. I did not remove the chassis, I only fed my continuity tester up to it to see if it beeped. It did.
Please tell me what to check next. I keep hearing in the back of my head, "you fried your flyback". I hope that voice is wrong.
