Original Ms. PacMan cockatil fried (montor?)- help to fix/upgrade(?)..
I have an original Ms. PacMan Bally/MIDWAY cocktail machine that I have been enjoying for many years (it is 100% original except I replaced the ROMs with the sped-up game version). Recently when I powered on the cabinet there was a loud "POP"/"CRACK" noise followed by a faint electrical/sizzling hum noise and a small amount of smoke coming from the cabinet. Needless to say I immediately pulled the plug. I opened the cabinet and could see that a thick upside down 'U' shaped piece of metal on the pcb associated with the CRT had exploded/cracked apart (see attached picture). At this point I unplugged the power connector going to the CRT and plugged the cabinet back in again- all of the cabinet lights came on as well as the cabinet fan. Unfortunately there is now no audio when I drop coins in and press start buttons- so I do not know if the main game board is broken, or if it is just a speaker problem (since the monitor is unplugged and I can't see anything). I can plug the monitor power connector back in- and there is still no change (monitor is now dead- and there is no audio response to dropping coins/pressing start buttons- volume adjuster on PCB is up).
At this point I'm not sure what to do- I think the built-in power supply is ok, but I suspect the monitor and (maybe?) the main game motherboard is dead..
Aside from this the overall condition of the cabinet and internal electronics/wiring appears to be in superb condition..
Is this cabinet a good contender to switch to an LCD screen, and replace the guts of the original motherboard to some kind of multi-cade/MAME/lots-o-games type situation?
Thanks for any advice/tips/pointers..
