Sorry, stepped away for a moment again.
I'll make you the same deal. I'll send you an MPU board and you can continue testing with a known good.

Hey, At least your learning and your getting great help.
You will have it up and running soon.

You are the MAN NeonKiss!

Not sure how this karma thing works, but you guys bot got  from me!

[CommTech]

One right back at ya for doing such a great job   

[Powerlinemanco]

Thanks!

I just wanna throw this out there. You guys are awesome! I'm so appreciative of all the help. I actually traded my Alvarez guitar that I bought in '07 for $2200 for this slot machine to have as a piece in my man cave. The guitar was worth substantially  more than the slot machine, but the guy wanted it for his son who was a music major and had never been able to afford a real nice guitar, and I really wanted a slot machine for downstairs. He didn't tell me there were quarters in the hopper still. I thought he'd emptied it. When we loaded it I heard them spill out, but when I got it home and unloaded it, i was in a hurry, and just didn't think before I powered it up. So you see, I'm really bummed about this whole deal because that guitar was my baby, and even though it went to a good home, I'm ticked off at myself for being an idiot and killing the slot machine I traded it for. So that's why I'm so anxious to get this going. Again, thank you to everyone here for your help and expertise. It really means a lot.

My best guess:
1 hopper jam - pull the hopper. You might get a 3300 error but that can be cleared by opening/pressing white button/closing door.
2. You won a jackpot - turn the jackpot reset key. Do this twice. Then open/close door.
3. Quarters or such wedged under the motherboard. With the hopper out use a Home Depot paint stick to fish under.

Found a broken trace from cr13 to u66 on mpu. Preemptively pulled out display board and checked it for broken traces. Couldn't find any, so maybe this will be it...

OK Eric,
Here is where I'm at with your machine parts.
I have a tested and working MPU board and Installed a SP731 chip and a SS6739. I matched it up with another known good and working Motheboard. I installed them in one of my machines and cleared all the old memory, used a set chip and programed it to a quarter machine and activated the bill validator. I have this running in my machine and will leave it up for another few hours.

This time you will get the MPU with all the chips installed and programed along with the Motherboard. It should be a plug and play with no programing required, just use the entire set I send you.
This way we won't have to worry about the chips that you already have or bending a leg on a chip when transferring them over.
I'll even send you a Set 15 chip. You won't need it at this time, but if you ever decide to change game themes and buy another game kit you might need one.

Can't remember if you said if you had a bill validator in that machine? I did activate it in setting so it should not matter if you don't have one.
Post up a picture of the machine from the front so we can see what you have.

Alright, got the new parts. Installed them. Machine is working correctly!!!! at least as far as I can tell. Only problem is the display is still not functioning. May need a new one of those too? Or is there a way to diagnose or trouble shoot that as well?

Ok, rechecked j/p 207 for dc voltage. .13 dc voltage present between pins 1 and  2. I also now have 9.8 vdc between pins 2 and 3.

Are you sure your pin numbering is correct?    Pins 2 (middle left) and 3 (Bottom left) should have 7 Volts AC between them.  
Pin 1 (Top Left) and Pin 2 (Middle Left) should have the DC voltage on it.

[Powerlinemanco]

I get 21 vac between middle left and bottom left.

[Powerlinemanco]

I get .11 vdc between top left and middle left.

[CommTech]

That is very strange. 

I am leaving work now, so I will pick this back up in about an hour after I get home.

[Powerlinemanco]

Sounds good.

[Powerlinemanco]

Ok, I checked between pins 4-5 on the molex connector for j/60 on the display board. I got 10 vdc.

Very good. That is the source voltage I was looking for.  

So your display has the proper DC voltage but is still blank, and the machine seems to operate correctly.
You now have a known good MPU and motherboard.
Sorry to say, but It appears you also have a bad LED display board. 

[Powerlinemanco]

Great... Um, Neon!?! Little help?? Lol...

[Powerlinemanco]

Oh, and my bv isn't working but I'm not sure it did to begin with. Fight that battle later I suppose... Lol

[Neonkiss]

Great... Um, Neon!?! Little help?? Lol...

WOW, Well at least you can play the machine for now.
When I shipped it, it had 50 credits on the machine. Are you able to get it to coin up with quarters?
I'll have to see if I have that display. I know I have the older version, but that won't help you out.

[Powerlinemanco]

Yeah. I can put quarters in it. It seems to work great. hopper works, sound works, i just need the dang display... lol. It has about 360 credits on it now... Lol. Any good place to start looking about the bv? Maybe I can figure it out...?

[CommTech]

Eric has the older version (vertical stacked) display.

Does your BV make any cycling noises when you power up the machine?

[Powerlinemanco]

I don't recall hearing anything but ill check it out when I get home. I'll also post a pic of the display board.

Great!  Also ...

Any Red LED's visible when you look into the front of the BV? (I am wondering if your unit is getting power).

I know you have an external side mounted BV ... can you post some pictures of the unit itself, as well as the harnesses that feed through the side hole into the cabinet?
