monitor? or something else?

[dirt]

i have a jamma machine and it used to work fine. it has not been played for about 2 years. i turned it on and this is what i get. its the same with different boards so it is the machine. anyone seen this before. http://www.youtube.com/watch?v=pkm-u6oUTOs


i forgot the mention that the monitor was a new happs i put in right before it got put into storage.

Are you using an adapter for this board? That could be the issue.

otherwise, stick a true JAMMA board in and see how that works...

 

[dirt]

yeah it is hooked up with an adapter. the other board is thru an adapter too. i'll have to look and see if i still have a jamma pcb. i'll post the results.

 

[dirt]

its not the adapter. i just plugged in a 60in1 board and i get the same result as the donkey king.

did you change any of the monitor wiring? exactly how long ago was this monitor put in?

If it's been 2 years, I would guess a cap on the power supply. I have two games that did that- one, a Dig Dug that hadn't been run for the winter, and two, a Donkey Kong Jr. that had been in storage for years before I got it. A cap fixed both.

all the wiring is the same. it was put in the cab about 2 years ago but hasn't been played since.

i'll try changing out the switching ps and see what happens.

I would expect the problem to be caps then. In storage (non climate controlled) the caps will dry out faster, and there were a lot of bad caps being made a few years ago and might have found their way on this chassis...
