Igt s plus 5 times pay

[Patrickmerc]

Good morning all, I have a s plus upright that I have no digital display and the candle keeps flashing. It appears that it thinks the door is open. I replaced the optic switches on the door and no change. For the display I replaced the power supply harness and the motherboard. Still not working. Thank you Patrick

Check the 3 fuses.

---------this needs moved to S+ section--------

[Patrickmerc]

All fuses good.

Regarding the optics.....
- There is an emitter and receiver -  do you have them installed correctly. Ie the Emitter worn't work if its connected to the wrong set of leads.
Using a digital camera (camera on a phone is fine) you can point that at the emitter and you should see a faint flashing. This will at least prove the emitter is working.

- Do the emitter and receiver match up (aign) properly - it doesn't take much for these to get out of alignment.
You can try taking the emitter and receiver off the door and tape them together. This will fake the door being closed - if this works then its alignment.

Are the reels stiff to the touch or are they loose ? this could point to the power harness.

Pls post back and let us know what you find out.

[Patrickmerc]

I looked at the emitter through the camera all I saw was a small spot of purple light. I manually held then together with no changes. I have two sets of optics and neither worked. The reels are stiff.

[Patrickmerc]

I checked the molex connectors on the back of the board and the denomination light only comes on with a light pull on the connector. The digital display will only light up one number on the display and it changes numbers every time I plug it in.

Sounds like your optics are good.
The little dot of purple is about what is expected.

Was the slot working for you and just stopped or did it come to you like this ?

Do you have a clear chip ?

[Patrickmerc]

I . I bought it not working. I have an s plus ram clear chip

[jay]

If you have another S plus MPU  from a working machine. I would try swapping them and see if the problem remains with the chassis or not.  You can also run the ram clear through this machine and see if it makes a difference. The other thing to check is if your game and real chips are properly seated in the sockets . I.have seen a corrupted game chip cause this kind of problem in the past, but it’s not common. Once again, it looks like your optics are behaving and you don’t appear to have power problems so now we are looking at the MPU as a potential source of the problem

Which harness connector are you giving a "light pull"?
There's two of them.

Maybe you could you post a close-up photo of it?
Might just be a loose ground wire?
Pull off the connector and push all the wires firmly into the back of the housing.
Once you do that, re-install the connector back onto the display.

[Patrickmerc]

The one on the right with the door open

[Stayouttadabunker]

The digital display will only light up one number on the display and it changes numbers every time I plug it in.

In which window on the display is this changing number shown?

Check the connector wires for continuity between the connector and the motherboard.
Could be a internal broken wire inside the covering that you cannot see.
You could also have a cold solder joint on the display panel header that you may need to reheat.

The only way to fix this is with a multimeter and soldering pen.

[Patrickmerc]

Thanks l will check it out. When I plug in the connector the numbers show up in different windows.

[Stayouttadabunker]

You should never plug in or remove components with the machine's power switch ON.
Sometimes you can, but generally it's best to turn off the power.

Because you are NOW saying that other LEDs light up in other windows tells me that your display could be fine.
I'm leaning towards a problem elsewhere such as your MPU or motherboard power connector.
With the power OFF, pull out the MPU board and check the pins underneath it for a bent one touching another pin.

BTW Does your reel glass display look like this one, from behind?
It has two separate connectors.

I pulled the mpu with the power turned off and then connectors look good. Yes that's the same circuit board in the picture.

the candle keeps flashing. It appears that it thinks the door is open.

Note that the lower portion of the candle will continue to blink with most SP chips until a paid game is completed, so be careful in assuming that just because the candle is blinking that the machine thinks the door is open, because that may not be the case.

You will need to get your display working in order to troubleshoot the exact issue(s) you're encountering with getting the machine to work.

If you have a later Splus with a BV then make sure to check the cash box door switch. With out that, it will never see the door closure.

[Patrickmerc]

Yes I have a bill validator. Where's the door switch located?

[Patrickmerc]

I found the switch there's no harness in the door just two tie wrap bases.

[Stayouttadabunker]

Look behind the bill validator unit on the right wall of the cabinet.
Check to make sure two green wires are connected together.
At one time, those would have went to the cash box door lever switch.
