I am trying to get the above monitor working for my Dart Star 2000 dart board. Bought this non-working. I opened up the monitor and it was filled with dirt and smelled of burnt plastic. I replaced the bridge diodes and the caps and resistors in the 900 circuit. Then plugged it in and now the blue disk capacitor at C715 is smoking. It is the one near the big black block thing which attaches to the side of the tube. I will also replace the diode and resistors adjacent to the capacitor just in case.
My question is, what are the likely causes to make a ceramic capacitor burn in general and if you know anything about this monitor type, this capacitor in particular? I have fixed pinball machines many times but this is my first monitor. Thank you.
