Die hard not booting

[darkcat1]

I picked up this die hard arcade back in June.  It worked ok but randomly the board won't boot....I hope it's not the wiring...but I think it's the STV Jamma board

I know nothing about fixing eletronics

Where do it freeze?, or what do you see as your last screen? (Picture?)
Have you try test mode to see that the cassette/cart is recognized by the system.

Give it a good once over and pull the edge connector off, put it back on. maybe push down on the socketed chips.

Everything worked two weeks ago but now only the monitor comes on with nothing(once I just got white dots but it worked two days later).  I had someone interested in buying the thing last night that I need to call back...it's just too huge and I want something smaller instead

It's possible the power supply died.  Check voltages.

So the monitor gets enough power but the board doesn't? huh.  Don't have a multimeter but I do have a cheap jamma board that I don't care about...

Get it working and upgrade the BIOS so that you can play out of region games. There are some fun ones for the Titan!

My favorite troubleshooting saying is "think ASAP," Always Start At Power.

You have 120v AC coming into your cabinet. From there, it will split and go to your monitor and the power supply. At the power supply, you'll have 120v AC and probably 12v DC and +5v DC and -5v DC (hopefully it is marked somewhere).

Do you have any game audio coming from your speaker (aka, game playing "blind")? If that is the case, your power supply is probably fine and you should move your troubleshooting to the monitor.

Hope this helps!

did you clean the DIE HARD cart?
