This thread is in regards to topic http://forums.webmagic.com/ubbthreads/sh...ge=1#Post335420 Ok. So after much research and discussion I was convinced that the power supply was dead in my 4 player TMNT machine. I wasn't able to get any DV voltage readings from it so I found an old AT power supply and cliped the molexes and soldered the wires into the 9pin molex (which I clipped) of my dead power supply. I plugged it in, turned it on and TA DA!! The game powered up, the coin doors lit up and I could hear the game rolling. GREAT! So I grabbed another power cord and plugged in the dead power supply (the 120VAC still worked). I turned that on as well and the marquee lit up, but no monitor! The monitor just wouldn't turn on! I took my voltage meter and I was able to read 120VAC getting to the monitor. A 400V cap read right on 400V. And I checked the fuse and that read just fine. I don't get it...why isn't my monitor coming on? It's a 25" 8 Liners that I got about 18 months ago. Thanks for your help! It's greatly appreciated!

Hey everyone. This question is in regards to this topic http://forums.webmagic.com/ubbthreads/show...ge=0#Post335420 I got my voltage meter today and have been testing voltages on my power supply. I checked the AC voltage to make sure 120V was getting into the power supply and it looked fine. I also tested the isolation transformer for the 120V and that checked out fine (on both top and bottom). When it came to the +5 and +12, I had to trace the wires from the JAMMA harness down to the power supply, since they all ran into a 9pin molex. I tried every combination with the leads of my tester, but I didn't get any DC voltage coming out of the power supply so I imagine that answers the question of if it's a power supply issue. I do have one question though. How do I measure the voltage getting into the monitor? I wanted to make sure that the monitor was receiving the right voltage (I assume 120V AC). Where should I run my tester leads to get a reading? Also, should I test the fuse on the monitor chassis? How do I test that, and what voltage am I looking for? Thanks -Jim
