Mame / combo machine issues

[bwolf99]

Hi all,
Total know nothing arcade owner here.
I bought an arcade machine in Australia about 4 years ago, I was told it was a combo of mame and something else to give the best combo of games.
We came back from Australia and it sat in storage for 18 months or so, when I first got it unpacked it had a red screen, I pulled a few cables out and replugged and all was fine.
We moved again and last week went to play again as this new home is permanent, red screen again, I pulled a fee cables out and re plugged and now nothing, the monito says no signal and I have no idea what I have done.
If I put some pics up would anyone be able to help me at all ?

Hi guys, sorry for the delay, here you go !

first thing to check are power supply voltages, some lcd show a solid colour screen when the input signal is missing
there are two power supply, the meanwell looks to be a 24v which powers the lcd - this is working, the other is a atx power supply that runs the game board - i have a feeling this is bad, atx power supply are cheap. Multimeter is your friend here
you can prove the lcd by connecting a pc

Monitor appears to be powered direct from AC supply going by the kettle lead plugged into it and the breakout block.

Meanwell is 12v and 5v looks like possibly linked to the Fan and one of the Jamma connectors for Player3 and 4, cant see from photos if it goes to the main Jamma connector going to the game family PCB. It also doesnt appear to be grounded properly to the incoming power source.

Wiring is a bit odd using black for Live and Red for Neutral but that could be an Australian thing.

Would guess that one of the Jamma connectors is players 1 and 2 and the other is for players 3 and 4 going to the add on board to the game family PCB connected via ribbon cable.

Does the fan spin on the ATX PSU in the bottom of the cabinet that powers the game PCB?

Being PC based it could be the BIOS battery has gone flat and the BIOS settings have reset so it doesnt auto power on when the cab is turned on, not massively familiar with the board itself and how its supposed to work but am familiar with PCs.

Anyone live in the Uxbridge area ? Lol , I am lost

 

[bwolf99]

Anyone want to buy it if in Uxbridge area ? I love it but I loved it when I switched it on and it worked immediately, the fact I have pulled one cable out, put it back and it has now died has me flummoxed and I dont know where to start trying to get it working again so if anyone is local and wants to buy it let me know, cheers

Don't give up so easy dude, it's good to learn about them for future

The ATX connector from PC Power Supply is 1st question, depending on the PC Motherboard it could well need that extra 4 pin connected, I'd get that plugged first if it's not been

Hey mate, thanks, I really dont want to honestly. I have tried with that plugged in and plugged out so far.
So this is the issue I think, I turned it on, red screen so unplugged that whole atx connector, plugged it back in and since then dead, I couldnt remember if it was whole or without the 4 pin but I have tried it both ways and nothing , this thing above is definitley the issue I would say
