Working on a Stern Stars. Nice thing is I have a fully working one in my collection.
I replaced rectifier board.
Installed working driver.
I repinned every connector and replaced all pins on MPU. There was acid damage to the bottom of board. I cleaned up best I could. I resocketed the chip shown in picture. Checked continuity for every pin. All traces good.
So here is what happens. Game kinda boots, it cycles coils continuously. Where would I start on the board to find the problem
Quoted from zacaj:You sure you have those roms in the right spots? Usually MPU-100 games have roms in U2 and U6
Good catch! Game boots. Moved from 1 to 2 spot!
Ball not kicking to shooter lane. I'll check it out and report back. Thanks so much! Great catch!
