Title: Jamma cabinet with broken monitor...what to do...what to do.... Post by: NumminzAK on May 31, 2016, 03:58:33 pm So I inherited a nice Jamma cabinet that has a Bomberman PCB in it. The cabinet will turn on and there is sound. If you flip the coin button it will register and you can hear the game trying to run, but the monitor simply does nothing. Monitors are my achilles heal with these things. I'm completely self taught on Arcades and to be blunt, the possibility of death by electricity is something that keeps me from messing with monitors too much. Everything else inside the cabinet looks like new...so I'm guessing the monitor is simply dead.
I'm considering ordering up a multi-jamma board for it and putting in an old VGA computer monitor. It seems like the easiest way to go with this cabinet, but I have some questions. The only other machine I've built is a mame, and I simply put in a computer inside of an old Z cabinet and dropped in a full size CRT computer monitor. It's a total Frankensteins monster, but it does the job. I'm wondering if I order the right multi-jamma board with a VGA out....should it be as simply as removing the Arcade monitor, dropping in a Computer monitor and plugging in the board? Is there a different power requirement for anything? Do I need some kind of converter? I have had a 60 in 1 jamma board before that worked just fine in another Jamma cabinet...but the monitor was good on that one. So I'm stumbling a bit on swapping this one out and trying to get by with just putting in a computer monitor...I am willing to put up with having to plug in the monitor directly as a power source. Thanks in advance....I just have a pretty nice Jamma cabinet that I'm not trying to put too much money into. Unfortunately the button setup is only two sticks and two buttons per stick....so I was thinking another 60 in 1 in this guy with a computer monitor just to run the classics like Frogger, Pacman, etc....

Post by: legoman on June 03, 2016, 03:32:01 am If you're removing the monitor you're going to have to discharge it and risk shocking yourself anyway, so I'd try to fix the thing while you're in there. You can order a capacitor kit from Bob Roberts, maybe a new flyback too if that looks cracked. I'm a novice myself and I've been trying to do the same with an old electrohome, it's kinda a fun challenge. I'd bet your current power supply would be fine for a new PCB, but you might want to replace it with a modern switching power supply depending on the state of the old one. Looks like 60-in-1s needs 5V and 12V. Does anyone know if he should disconnect the isolation transformer if he does end up using an LCD monitor? Seems like there would be no purpose for it.
