I picked up a Galaxian cabinet cheap and everything was going really well. Fixed the PCB, fixed a couple wiring issues, put it all together and the K4500 monitor came up. Not the greatest picture, but working. The picture was a bit narrow so I decided to try adjusting the width coil to see how much improvement I could get.
Like an idiot, instead of verifying with the manual first, I just started adjusting what looked like the horiz width coil. As I realized in retrospect, there were two problems with this:
1- Since it is a vertical game, its probably the vert width I needed to change
2- It was actually the horiz sync coil (not the width coil) I was messing with
Suffice it to say that all I initially accomplished was to lose sync on the monitor. Not having learned my lesson, I blindly blundered on trying to readjust the width/sync until at one point I heard a high-pitched whine and then nothing. No magic smoke, but am assuming I fried something. At this point, I don't see a neck glow though there is power going to the monitor.
While I am pretty accomplished on the digital side (have fixed multiple PCBs), analog is not my thing. Any hints on where to look or is it likely game over? I do have a schematic but have no experience messing with monitors.
If anybody has guidance that could help save my K4500 from my bout with stupidity, I would appreciate it. Thanks!
