Hi all I have a spare jamma cabinet that would make a great mame cab. Free to a good home, you just have to collect it from coventry.

The Jamma Cab:-
I power it on and.....nothing. Silence
Having almost zero experience of Jamma cabs I ask around on a few dedicated forums to find out possible issues:
1) Power supply
Ok, might be the power supply. I get the multimeter out and test the outputs on the supply. A few of them are slightly high but it looks fine. I do notice that there is an adjustment screw that has been pushed in on the PSU, and will need to be pushed back out.
I'm stumped now as the power supply seems fine. So I take a a few pictures of the inside of the cab and post them on the forums. Whilst I'm taking the pics I notice a missing fuse from the right hand side of the monitor.
2) Monitor
Lots of replies on the forum with suggestions. Someone immediately points out that there are missing parts, hence why I'm not getting anything First of all a missing fuse at the side of the monitor Second the monitor has a missing control board. Without the control board nothing will be displayed on the monitor.
Ok, so I find a source for the missing parts and am now waiting to recieve them. Whilst I'm waiting I take the power supply off to fix the voltage adjustment screw that has been bent out of place. I carefully take it to bits and bend the screw back. I hear something snap - not good! Everything looks ok. I put the power supply back together and test the voltages again. Oh dear, I'm not getting the voltages I expect anymore. I think I've bust the PSU!
Back on to the net. I find a supplier of Jamma PSUs. Ordered one and will wait for that to arrive aswell.
good luck with this project m8 ive always fancied a arcade in my passage way to blank the misses in the sitting room lol think id have to buy a working one though as im poop at electrics
if you take the monitor out and drop it accidentally, the CRT (Cathode Ray Tube) is a bit like a bomb. It will implode first before it chucks fragments of razor sharp glass upto 30 feet.

It's nice to see the machine up and running, not sure about the footy game though, puzzle bobble is great fun. I just bought metal slug 2 for my new cabinet, hopefully it will arive by tuesday.
