Hello all,
First time poster and super newbie. Just came into an S+ Pinball machine. Everything works well aside from it does not make sounds with reel spins. Pinball bonus has sound. I have gone into the self test settings and when going to the sound test (50?), doesn’t make any sound when I test. Have also tried to adjust the reel spin sound setting but seems like that did not work as well. Just looking for some tips for this.
Once again, be gentle, I have little to no experience with slots at this point but that’s why I’m here, trying to learn!
Thank you!

Chip is SP984, 16mhz board

Does the pull handle work? The pull handle solenoid makes the reel stop sounds. It may be bad. (Very common issue).
-
First of all, a 16Mhz MPU doesn't have the blue volume dial on top of the MPU.
The game volume is set by pressing the little white Test button twice so you see a zero in the [Coins Played] window, your Test button can be located either up by the power switch, or behind the power swtch.
Turn the momentary Jkpt/Reset key once, until you see a "3" in the [Winner Paid] on the display, then pressing the Spin button to change the volume.
A setting of "1" will wake up everyone in the house and next door, while "9" is quietest. :rotfl:
Once you change it, just close the door. :hide2:
To change the Reel-Spin Sound, press the small Test button to get to the <0>, turn the Jkpt/Reset key until you see a [2].
Options are reel-spin tones and reel-stop sounds{0} or reel-spin tones only {1} using the Spin button.
So again, as a reminder.
Pressing the small white Test button switch “pages” forward through the self test mode.
To move through the options pages within page zero <0>, turn the jackpot reset key.
In your case, use Key to get to [2] for spin sounds or tones, or [3] for volume adjustments.
To change settings, press the Spin button on the deck.
Here's a link to some better instructions...>>>

Yes the pull handle works. I have gone into the settings (using the process described above) and set it to have sound while spinning. This didn’t work for me. I then went to the test page with 50 in winner paid and cycled through the sounds and hit spin reel for each, did not produce any sounds either. I also did not have any credits on the machine while doing all of this either.

The sounds for reel spinning and the dinging of credits counting up are produced by the speaker
in the coin tray. That speaker has a plug mounted to the tray that mates with the machine when the tray is put in place. I'd start by looking at that connection to see if it's properly connecting the speaker.
(Edit) ...that is above the coin tray, in the bottom of the belly glass. If that speaker is disconnected or otherwise not working it could result in the bonus sound working but the base S+ sounds not working.
-
Would a bad connection there allow for the pinball bonus to have sounds? I’m getting fine sound with the pinball bonus but just no reel spin sounds.
-
The bonus sounds may be coming from the topbox computer....not the machine's main MPU.
Show us a photo of your MPU....I'm wondering if you have an AY sound generator chip in there or not?

Hmm...there's a U27 Duart chip SCN chip in the socket next to the crystal chip.
You should have game sounds.
I find it strange that there's no AY generator chip....in fact, there's NO socket?
I forgot you have the 16Mhz MPU...those I've only had a few of them and never hooked one up to a pinball kit....only Barcrest-type of games.
Where is the speaker in your cabinet?
Down at the bottom of the door?
Speaker wiring good?
Check all thepins on the bottom of your MPU connectors...mae sure no pins are folded over touching another one or bent.
-
Yes bottom right of the coin tray. And it sounds that the bonus sounds come from that speaker as well.
-
Bottom right under the door basically inside the coin tray.
-
If I remember correctly the reel sound, etc, come from the normal speaker and the topbox bonus sound comes from the speaker in the coin tray.
-
Speaker
-
NOT the coin tray speaker....I meant the one on the bottom of the belly door under the fluorescent lighting.
Should be green and white wires going to it.
Open the front of the belly door and you'll see it.
-
Ah apologies. Yes it’s on the bottom left (looking straight at the machine) on the bottom of the belly door.
-
There’s some metal plating covering mine so hard to look at wiring. I’m attaching a YouTube vid, this seems to be the same style of machine I have with similar guts.

You're absolutely correct, and I had it backwards in my reply earlier. :duh: Thank you for the correction, and to CBRed sorry for the confusion.

You need to open the belly door -- it is hinged and designed to swivel open. While holding the belly glass so it doesn't fall open and shatter your glass, pull out on the textured knob on the right side of the machine (next to the door latch) and the belly door should open. See the attached pictures for a guide.
IMPORTANT: When you go to close and latch the belly glass door, pull on the belly door frame multiple times to ensure that it completely latched. If you don't do this, you risk it appearing to latch but not actually being latched, and then having the belly door fall open, potentially damaging your very hard-to-find belly glass.

I have fixed a sound issue on a 10MHZ S+ boards several times by replacing C43. The first photo of your 16MHZ looks similar, but I could not see the capacitor number. In the first photo of your 16MHZ MPU, look all the way down to the lower left hand side for the last capacitor on the board. It is to the left of C60. This capacitor is the last component in the sound circuit of a 10MHZ MPU, and it is in series. If it is open, you will not get the spin sounds.
-
Got it!
-
Thank you so much everyone for the help! The previous owners disconnected the speaker so all is well in the world. Thank you for laying it out so someone with the mind of a 5 year old like me could understand lol.
-
Thanks for letting us know what the resolution was for your machine -- glad it was an easy fix.

To revive this thread, I’m kind of having difficulty adjusting the volume now too. I press the self test button twice and it brings up a 0 in credits played and 2 zeros in winners paid. I’ve tried turning jackpot reset key until it says 3 but when I press spin reels, nothing happens. Any tips?
-
You need to get it to where you see a zero in the [Coins Played] window, and a 3 in the [WInner Paid] window.
Whatever number you have in the Credits display should be blinking, and is changed by pressing the Spin Reels button as many times as necessary to adjust from 1 to 9.
-
Would there be extra zeros in the winners paid window or would it only be a 3?
-
Also, make sure you have zero credits on the machine when trying to adjust any settings.
-
Open door, coin played 0
Press test once, coin played 0 winner paid 000
Press test a second time, coin played 0 winner 00 with second 0 blinking
Turn jackpot reset key 3 times (changes second 0 in winner paid) to 03, press spin reels and nothing happens. It just changes to the second zero in the winner paid slot (the zero on the left) and you can turn the jackpot reset key to change that number.
-
Just trying to make sure I’m not doing anything wrong. I’ve done this with zero credits on the machine and when I get to the 03 in the winner paid after pressing self test twice and turning jackpot reset key to get to that point, pressing spin reels just alternates between making the 3 blink and the 0 blink.
-
I just put in a 16Mhz MPU and an SP1019....SP1019 is a 16Mhz chip.
I had to see why you cannot change the volume.
On the first press of the little white Test button, I get 3 zeros in the [Winner paid] window and a zero in the [Coins Played] window.
On the 2nd press, I get a 2 and a zero in the [Winner Paid] window, and a zero in the [Coins Played] window.
I then turn the Jkpt/key once to get a 3 and a number 1 in the[Winner Paid] window...the [Coins Played] window stays at a zero.
That's when I see the SPIN button light up, and can press it to change the 2nd number in the [Winner Paid] for the volume adjustment anywhere from 1 to 9.
A setting of 1 is supposed to be the loudest.
When you set that 2nd number for the volume, keep turning the Jkpt/key until all the red LEDs go out or close the door and the game should be ready to accept a coin.
Good luck!

Got it, for some reason mine requires 3 presses of the self test button to get to the page with a 2 0. Thank you for the help!
-
Maybe it's because of the SP984...lol
That chip probably has that extra page for some reason...no biggie.
It would be in the PSR (Program Summary Report) for the SP974 chip...if anyone cares to look.
I'm marking this Topic as Solved!
