Only question is: what's U18? I am replacing from the old board to the new board as well, but I don't know what it does.

U18 is used for SAS and EFT communications. Unless you are playing around with trying to get SAS working, you don't need it.

Everything is in...powered on - the BV cycled, the reels moved slightly but no initial cycle and no error codes. When I shut this off (after cooking) it did have an error code but now there's nothing. I checked the dip switches and sure the IC's were seated and in the proper direction!

Make sure there are no pins bent on the MPU plugs. Also make sure the transformer on the tray is plugged in correctly (not offest). Also make sure the MPU is seated good. Some you have to really push down hard to get them to seat all of the way.

Are you getting any display at all?

Game and reel chips in the right sockets?

I know you probably already did this, but check all of the fuses again and the fuse holder caps.

Also, you might try leaving that pesky 9 pin BV cable unplugged in the off chance the BV is cooked and somehow messing with the MPU. Process of elimination.

I would remove all of the chips you transfered, and check all of the legs again and then re-seat them. Might even use the CMOS from your old board (just in case the other one is bad or something). One bent pin os all it will take to make it not boot.

If your board has jumpers by the game and reel chips, make sure both are set the same way.

It's possible your new board is bad. I don't think there is anything else really wrong with the machine since you did get an error code even with the cooked MPU. So it was booting up to a point.  You can always try putting the old one back in just to see if it still gives you an error.

Okay...I'll try...also one thing - the transformer on the MPU case does smell although there's no physical evidence of it being burned...but could I have fried that? I hope that, most likely it's just residual smell from the resistor pack.

See my edit above about how it was booting to a point before. So your MPU transformer is probably good.

Jumpers were all okay and yes, I did unplug that 9 pin already...just in case. Do you know what U 54 does? Should I put the one in from the old board? This was a tested and working board, according to the seller...he's on this site so I'm sure he's highly reliable!

I'm going to try sticking the old board back in and see if I get the error code.

U54 is the CPU.

I would try putting your old board back in first to see if you can get at least an error or some display to come up. That will help to determine if you have other problems, or if the new MPU has issues.

Old board in. I get error code b1 and the top candle lights start to flash - it's the CHANGE candle and button that light up and flash.

b1 or 61? 61 is normal any time you fiddle with the CMOS. In any case you are getting something. I hate to say it, but I think you got a bad replacement MPU.

But you can try swapping ALL of the socketed chips again and see what happens.

I think that is a 6...if the top segment was lite, I would have called it a G !

There are no letter codes, that is why I asked. If you still have the old board in, you should be able to press the self test and have it change to a 61_1 If it does that, I would not go any farther since you know you will get other errors. But it shows the machine is booting. If the replcement MPU is not at least giving you a 61, I think its bad.

I can see how a S+ n00b would call it "b1":

(No offense intended at all with the term "n00b" -- I was one not that long ago, too!)

No offense whatsoever! I'm VERY happy to be here...new or not! I've never seen a group of people as helpful - anywhere.
As a side note anyone know what happened to Emelie? That was a very fun and informative thread going on.

One chip I didn't swap out was U54. Should I? Maybe it's the culprit?

Can't hurt at this point. You know your old one is good.

Nothing...no code. Last chip I just realized I didn't swap out is U49. What does that one do? I'll just try it...

Sound chip. Probably not going to help.

Okay, nothing happened...no code.

I would. I think we have pretty much determined that there is something wrong with it.

I would just check those two grey connectors on the bottom of the MPU one more time to make sure there are no bent pins. I know you already did, but I had one that would not boot and it turned out there was one pin bent causing the MPU not to seat all of the way.
