Sinbad startup and 1000 chime.

Just another view on this...
Have you checked you are getting the correct voltages out of the power supply, ie 60V? If its too low you will have intermittent boot issues.

Also, Clay's guide has a video (search youtube for Clays System1) where he talks you through the boot up sequence to help you diagnose where the problem might be.

A1J1 on the MPU (from power supply) can cause intermittent booting problems like you describe.. i have the same issue with my Buck Rogers where it sometimes wont boot up until i reseat the A1J1 connector, (one of these days i'll actually get around to repinning it)   try repinning that connector.

Personally i would be doing ALL of the connectors and be done with it.. it really is the only way to ensure reliable operation and will most likely eliminate the problems you're having. Also make sure the connector contacts on the boards are clean if they havent already been cleaned.

Yeah, I'll do that...it sounds like you should be taking your own advice with the repinning

I had the power supply tested along with my other boards and it got a perfect bill of health. I've got tomorrow off so I'm getting stuck into the repinning starting with the power to cpu cable which, for some reason, I only repinned half of.
I've ordered a new coin door decal & some more Led's just for the inserts so they don't get anymore heat sink.

I would if i could only find the time     too busy fixing other peoples games to do my own.. hell i still have that bloody Pinball Pool sitting there not even half done, having been not touched in over a year!

I guess i'm lucky in that my duck dodgers only very occasionally plays up and wont boot  its pretty good most of the time, which is another reason i havent repinned any connectors on it

Yeah, mine's great once it gets up and running so I can't complain...it wouldn't be pinball if there wasn't something to fix!

[Sinbad79]

My Sinbad is the same, only lately have i been forced to start repinning because the boot problems have just worsened to the point where it is annoying.
Broke my pin extraction tool too!!

What are u guys eusing to remove pins from connectors? Small electrical screw drivers?

[Klondike]

I bought a cheapy little screwdriver type kit that has one that just comes to a point...not sure what it would normally be used for but it's been doing the trick for me.
I'm going to go back and re-do a few of my first attempts as they were a bit iffy...it took me a while to get them looking as they should.

Very true   i often think they are like old cars in that they always seem to need something done to them no how small or insignificant!

 I repinned all the connectors and cleaned up the chime box & replaced a charred diode on the 1000chime and Sinbad's working perfectly now.
Thanks to everyone who offered advice & assistance!

[Mr Pinbologist]

Good stuff  glad you got it sorted

Have you seen these:
Gottlieb System 1: MPU to Driver with diode protection

http://www.bigdaddy-enterprises.com/harnesses/harness-index.htm

If your driver board is the one without the diodes then you should consider one of these to protect your MPU.
At $34USD they are not too badly priced.

I might grab one of those. There was one on ebay last week that I was bidding on but got pipped at the post...don't you hate that?
