We are restoring and Adams Family and the machine will not start up.
We have a rotten Dog MPU, Rotten Dog general purspose driver and Rotten Dog dmd controller. The two flipper boards and sound board have been checked so we know they work. Transformer and filter have been checked so we know they work, they were from a functioning machine. Ribbon cables are all new and have been seated and reseated.
When you turn the power on D19 & D21 light up on the mpu, D10 lights up on the dmd controller.
On the Rotten Dog General purpose driver board the 12v & 18v leds are out. The 18v comes up as 7v when tested, the 12v has 6v, and the 50v has 76v.
We have fitted the cables to all the boards, so not 100% sure that all cables are in the correct spots.
We also fitted a new coin door.
Any help in getting it started would be greatly appreciated .

We have just replaced fuse F114 and all now the leds are on, but the 50v is still 76v.

Thanks , we were not sure

Thanks, that's J120 that belongs to the backboard lights, we removed it for easier access while trying to figure this out.

Thanks, have done that a couple of times, we did accidentally reseat into wrong spot and kept blowing F112. Still does not boot up.

Have done this just now and machine still won't boot up. We got the ribbon cables new from Marco not too long ago. We have some original ones here from another machine we will try now

Just swapped over ribbons from a working machine, but still no sucesss

We have not tested the mpu, it is new though.
We removed the three ribbon cables from the mpu, turned the machine on , led d19 & d21 come on, d20 does not flash. Pushed on ASIC chip, no luck.
Could there be a country lock on ? As we are in Australia ? Thanks for your help so far

Thanks, we will source another MPU ...

Thanks..is this ok ?

thanks...we have heard this but we're hoping for the best

Will do this ... we thought the voltages were ok 5v is running at 5.1v , 12 digital is running at 11.9 . We did buy getaway to help with the Adams build , but have grown to love it so don't want to compromise it too much, but it is handy to have in this situation .

Just checked the getaway board in TAF and it boots up, thanks so much for your help, it sure put us on the right path quickly , really appreciate it ! We can get a new mpu, so will get that and go from there .

Just tried this too, but no change . With the Getaway the D19 went out and D20 started flashing ..picture does not show properly .

We don't have a chip puller unfortunately, we got from Curly in Florida and when it arrived the box was pretty battered up, more than likely from Aust Post. We will take it with us to our guy that's got the mpu..we will get him to have a look at it and reseat it. We would end up wrecking it without the puller.

Bought it complete. All parts installed ready to go .

No...we don't for sure.

We found some tools and have taken the ASIC chip out, all seems ok

Yep..tried to that, still no success....

Again, thanks so much for your help, we are now thinking ( with your help) its something on the mpu the game rom chip . We will get the new board ...and then we will find all the other things wrong It was a full rebuild , parts were missing (door, boards etc) and it had been sitting for many many years.
My husband " pinballaddicted" sends you many thanks , If you are ever in Australia you need to join us for a beer and a BBQ !!

Yep..that was one of our concerns too...but when we very first turned the machine on it did the same thing, it was only when we started messing with it we accidentally misplaced the cable .... it's all new though to us...we have only ever had new machines, this has been a learning curve for us ..we will keep you updated on the progress . Time for Pizza and pinball now thanks again

Thanks....after we bought these boards we were introduced to someone local that can build and repair, so we won't worry about warranty...and really we do not know for sure if we caused it or not...so it's all good .. it will be interesting to know of the the exact cause and problem though.

Thanks !! It really is a great community to be able to come on here and receive so much genuine help, we really appreciate it that's for sure !!

We have success, thanks so much again for pointing us in the right direction, we picked up a new board this morning and everything works. ....that is everything except thing...but we are sorting that out now ...possibly a new motor .

The machine was missing some boards when we picked it up, so we bought some from rottendog. (The main driver board works fine from rottendog) Have since met a great guy locally that can check, fix and supply some boards (we now have homepin board in it that he supplied us) Also getting him to check the Rottendog board checked to see what stopped it from running. It could of been us for all we know that had some wrong connections that stuffed it up.

Thanks...playing games now...just disabled thing for now..it's a great machine !! Also Just sorting out some really minor other issues , but it plays great .
And yes..colour dmd is next on the list, it's a must, now we have it working . thanks for the link

Thanks ..yes we did see that they are out of stock, have sent them an email ..we can wait
