Just rebuilt a Cinematronics display board, using this parts list: (www.biltronix.com/arcade_electcomp_01.html#Star_Castle_Monitor_Board)
The Circuit breaker is tripping after a few seconds, but only if the display is connected.
Game plays fine blind.
I smoked a few resistors after the breaker tripped (in the R123 - R129 row: R125, R127, R128). It didn't trip breakers before I replaced all the parts
-- Obviously my error. Should I disconnect the HV, CRT, & Yoke before troubleshooting the board? I'm afraid keeping turning it on will only smoke more parts.
So here's a dumb question -- in general, what causes the breakers to trip? I know the circuit pulls too much current, but what causes that? Is it usually shorts? I'm trying to pull together the troubleshooting tips from the various sources
Does this ring a bell with anyone? I'm going through the troubleshooting tips in the various FAQs. any help is appreciated.
