So I turned around the game was frozen. I power cycled the unit once and this is what I got.... I haven't tested voltages yet, but I'm thinking that if I'm going to do anything, I might as well recap the power supply and anything else I can in the cabinet when I tear it down.... any ideas of what's wrong? Nothing happens with service buttons or player buttons. Any wisdom is much appreciated.

unfortunately no... I was going to recap everything, and maybe check the rectifiers when I get a chance. This was supposed to be my game to play not fix :(
 
This is why you don't let toddlers sit on top of the game.:D

Test your power supply, and I am pretty sure you will find your problem.
 
Check the vlotages on the RAMS and also at the ROMS. This is commonly either a power supply issue (don't be surprised if capping doesn't clear it up) or the ribbon cable between the MPU board and the ROM board.

Don't think it was him sitting on it, maybe it was when I let him chew on the caps? J/k going to start diving into this after the weekend, I've got some commissioned projects to finish....and it's time to start generating instead of leaching money.
 
Check for cold solder joints on the header pins on the power supply and CPU and reflow if they look questionable. Then check the voltages at the RAMs as suggested.
