I powered up my 6-player x-men, monitors both were working fine, speakers were humming, so I was going to try to open the test menu to take a look at the audio settings. Pressing the test switch while the game was on didn't seem to do it, so I powered off and held the test switch while powering back on. This started the EEPROM test, and then after it tested (and said it checked out ok) the screen was blank and the second monitor wasn't on.

I tried to adjust the monitor with nothing coming up. The 2nd monitor (right one) showed a blank screen and then went off. I noticed in the manual that when you hold the test switch it initializes the EEPROM to default, so I'm thinking something got reset?

At this point, nothing is displaying on either monitor, the left one is definitely getting power, and is glowing, colors can be adjusted, but no menu display or anything. I hooked up another pcb with a bad rom chip, and the rom test opened up so I know the monitor is ok (that second pcb doesn't ever get passed the rom test though).

Any ideas? I tried to reboot a number of times, holding test switch, not holding test switch and waiting a few minutes then holding test switch. No luck yet. Thanks in advance.
 
Are you pressing the test switch that's on the pcb or the other one mounted just inside the coin door? The manual specifies holding down the one on the pcb to do the eeprom initialize.
 
I used the button, not on the board itself, but from the manual they appear to do the same thing. I know it did the eeprom initializing because it said it on the screen before going blank. It seemed to run some sort of eeprom test, and when it finished there was no menu or anything, just a blank screen.

Interesting. I did this eeprom initialize one or twice for some reason. I remember I had some trouble getting it to boot back up, but it wasn't too bad. I wonder if it could be the eeprom itself that's bad. Not sure if those are soldered to the board or socketed.
 
Yeah, I don't know if it's even an eeprom problem. I'm just looking for some sort of different way to boot it up that might allow it to boot because it won't since the eeprom initializing. There's a note in the manual mentioning that it will happen, but not that it affects anything or any way to troubleshoot after doing it.
 
Update - I was able to get it to boot again, the EEPROM initialization just coincided with a loose wire in the jamma harness somewhere. I was able to get the picture back in the left monitor. Now the right monitor isn't powering up though (while the screens were blank, the right one shut off completely). Any ideas? I swapped the transformer wiring from 1st to second, and it still didn't turn on. Might be a break in the wiring from transformer to monitor I'd imagine. It cut off while I was adjusting the "satellite adjustment knobs" that are located under the control panel.
 
Thanks, I'll take a look at that. Anywhere else I should check for broken parts? Also, how do I know if a pot is bad?
 
I would also try swapping the remote board for the working monitor with the one for the non-working monitor (Assuming they are the same unless someone changed out one of the monitors). I'm not sure if something failing on the remote board would cause the monitor to appear totally dead, but I've often seen people say to never run the monitor without the remote board hooked up. If you swapped the power wiring over from the working monitor and still have nothing on the other monitor, you should start by making sure you have the 120v AC at the monitor's power connector. It's probably a 2 pin connector and should run right from the transformer up to it. You could also double check and make sure a wire didn't slip off the isolation transformer or something simple like that.

Edit: You may want to also start a new post in the monitor forum to get better and more responses now that the problem is monitor related and the board is running.. Check what model monitor you have (probably Wells Gardner K7000 variety) too.
