ok my pinbot is driving me crazy
1. sometimes it takes two or turn offs and turn ons to get it to boot
2. sometimes during game play it will lock up and sometimes show chiness on the displays
3. sometimes during mutiball the sound will lockup and not come back till the ball drains


heres what i have done

1.run a cpu test and it told me u26 rom is bad changed to all new roms worked fine for one day
2.yesterday i was playing and we had a power outage and the game is back to its old habits


any help would be great
thanks

Check for cold solder joints on the power supply and the cpu board. Also check repair guide at Marvin3m.com

Have you replaced the batteries and checked the out put with a volt meter to see if they are making contact with the battery holder?

Key work here is worked fine till the power went out, so if it is not holding memory it comes on in diag mode.
 
I did change the batterys at the time change
I will check for voltage at the holder

I did take my power supply from my highspeed and as of now its working much better
the game now seems much brighter and functions really good

I put the pinbot power sluppy in my highspeed it does work but doesn't seem to be as bright as it was

I will check all the voltages and report back

Thanks
