S+ lights up, reels stiff, but no displays

Mother board ? Or MPU ?

The motherboard is the small fixed board at the bottom of the cabinet and the MPU is the large removeable board.

Jim (from this forum) - can likely have your board tested / repaired and/or replaced.
Pm him

Okay.
I recieved the display, the motherboard and the MPU in the mail this morning.
First thing I noticed was a horrible battery holder install.
The battery soldering pads were completely falling off of the MPU. ( From being overheated too long).
Someone tried to stuff the holes with wire in a vain attempt to make continuity to the backside...

Anyways, I ripped everything off, and re-soldered everything back the way it should be.
I tested it in my bench tester and found out your MPU was stuck in the [61-1] Loop.
I ran a Clear chip and re-set up the board in the options.
It's now set up for .25 cents and to lock up at 1000 credits.
I hooked up your long reel glass display panel and it works fine.

But when I installed the motherboard, there was no display although the machine accepted coins and played normally - just zero display.
When I took the motherboard out and rehooked back my tester motherboard, your display came back on.
I tried everything but I'm certain that there's something wrong with the continuity on the motherboard somewhere that concerns the display circuit lines.
It can be a broken trace, or a cold-solder joint too.

I re-heated solder that runs on the power traces and MPU pins to the display.
I also sprayed De-Oxit on the pins for the MPU and header connections.
SOMETHING is wrong with that motherboard.
There's quite a bit over overheated looking areas on the board as well.
There's excessive staining all along the MPU header pins that plug into the motherboard...it hard to tell what it was...soda, flux?
Something hot fell onto the motherboard and it's has lost continuity between the component side and non-component side.
There's tiny, minute solder bits everywhere on the board.
I suggest that you get another motherboard to replace this one.

You will need to get a hold of member Jim of Midwest slots for a motherboard and ask if he has a Clear and SET015 chip for you as well.
 If not, maybe member RB will have some chips for you.
Your SP731 and SS6624 software chips are fine.
PM your email address to me so I can give you more information.

You guys have to see what I saw when I opened the box...WOW!

K+ Mark for your efforts to help this member.

Thanks Knagl,
You know me too well...lol...I like trying to help members.

There's basically 5 wires that light up the digital LED numbers on the display panel...>>>

Pin-1 Gray w/blue stripe
Pin-2 Gray w/purple stripe
Pin-3 Gray
Pin-4 Red w/black stripe
Pin-5 Green ground

These run thru the main door harness back to the two long, black thirty and forty pin headers on the rear of the motherboard.
From there, they go all over the place on the motherboard traces to different pins....some traces run thru and under the board.
Trying to find the break in continuity is next to impossible I'm afraid to say.
To make things even worse, there are OTHER gray w/purple stripe wires or solid gray ones   - that only multiplies the difficulty in pinpointing the problem line.
Because of that, I had no problem suggesting the best move was to find a replacement motherboard.

Hello Everyone,
Update:
I have the new motherboard and a candle installed. After Mark checked out my boards. Everything but the motherboard was good. All parts are installed and the display is now working.
I have a 65-1 code in the winner paid display and the top light of the candle is flashing slow and the bottom is flashing fast. What next?

Stolen from another thread…..

As far as as 65-1 error, the correct procedure is to open the door, press and hold the self test button for a couple of seconds, then release it -- the error should clear.

A list of common S+ error codes and their resolutions can be found here: http://www.newlifegames.net/igterrors/

Hi Jay,
I"ve tried pressing the self test button. That clears the error for a short moment then a 2 flashes in the coins played and the 65-1 error is back. The candle flashes slow at top and fast at bottom. The new MB from Jim did fix my diplay. Very close to playing now.
Everyone has been a big help in saving this machine.
Thanks,
Chet

Double check
Your game and reel chips. Make sure one is not in backwards or that there is no legs bent under.
Regarding the right way to orient chips there is a small hole on the top of the chip that goes the same way as the knotch on the front of the socket.

Leg bent under is my archileas heel.

[Stayouttadabunker]

The [65-1] error means that there is bad data in the small, 8-leg 24C04 EEPROM on the motherboard.
Normally, ones opens the door, and holds the Test button for a few seconds, to clear it.
Don't just press the Test button, hold it until you hear a "ding" or 3 seconds.
At that point, you close the door, the machine boots up, the reels spin from right to left, and the Insert Coin lamp comes on.

I held the test button until the error stopped displaying. I did not wait for the ding. I'll try that first then disconnect the candle and try again. The display problem was solved by replacing the mother board. The old motherboard did not work in a different machine.
I have a display!!!
Thank you everyone,
Chet

It may or may not "ding", what you want is the [65-1] to go out.
You were supposed to close the door next.
