I recently replaced a battery and did a clear, then set up denomination, etc. on a Gamemaker. It worked fine for about 3 weeks and now when I turn it on, I'm not getting anything on the screen at all and it won't coin up. The monitor seems to be ok, power wise but nothing else, no sounds, no touchscreen response, nothing, lol! Any ideas on this?

I would check the power supply.

Are all of the green lights lit on the front of your board?
If so check your power supply voltages with everything plugged in and powered up.
Attached are the test points on the silver power supply.

The only green light that is on is the +24v, the other 3 are not lit up

Open up the power supply, you probably need to recap it.

The 24V is generated with a Full wave bridge and a large capacitor tied to the main transformer.
The +5, +12, and -12 voltages (the other green lamps) is produced via a small switching power supply module inside the power supply box.
It is cheaper just to replace this module than trying to troubleshoot the bad one.
There is a sticky somewhere on this site, placed by me, that tells you where to purchase a replacement module for under $20.
I think it is in the Bally 5500 section.
Find that, order one, and be done with it.

Thanks guys, it was the power supply, I just robbed one out of another machine that I had, I will repair the bad one from the instructions from above.
