i tested power at the power supply getting 5.1 and 13.4 is the 13.4 to high on the 12v side? just recapped the power supply and still have the my issue if you leave it off over night or for few days when you turn it on some of the speech is out of sync or just saying wrong things if you flip it off and back on it is back to normal or after a game or 2 of playing it will fix its self as well , is this a rest problem or possible cap on the mpu board or could the 13.4 be to high on reset section and any thoughts on doing a reset mod with the MCP120-460GI/TO chip any helpful advise would be great ........already has leds ,nvram and no acid damadge other than issue listed game functions 100%

ill give that a try pull em clean and reflow but idk after you start it it can run for days and never act up almost like a week capacitor once its charged up its fine

i did it was around 14 and never looses any sounds it just says some of them wrong like when it puts ball shooter lane in it starts police talking or when suppose honk it says red light those are only 2 ive noticed so far

update problem seems to be gone but only time will tell i ordered new set of roms old set had 2 rev 2 and 2 rev 4 put new ones in and for past few days there been no issue
