I put new battery in. Now no sound.
To turn on sound for S+ do you use set chip or other way?
SS 3633         SP  878
Thanks Ford

10mhz or 16mhz? If 10, did you maybe hit the volume dial? On a SP873 DIP switch 3 is for spin sounds.  I don't have a PSR for a 878.

10mhz or 16mhz? How do you know?
If 10, did you maybe hit the volume dial? Did not turn volume control. Doesn't make a difference where I turn it.
On a SP873 DIP switch 3 is for spin sounds. # is on.

I thought that when battery died it lost setting & there might be setting in program to set.
Thanks, Ford

If you have a volume control on the board, it's a 10MHz.  For giggles, have you tried taking out the board, turning switch 3 off and on a couple of times, and reinserting the board?

Does it affect the coin in and rollup "ding" sound levels? It should. You can also go into the sound test and use it to adjust the volume. 

I would make sure that the overall sound is working and adjusted properly before continuing to troubleshoot the spin sound problem.

Tried it. Didn't work.
If there are no settings in program I'll have to find a speaker & try that.
They had wires shorted out & fusses were blown. Then it laying around & battery was dead.
Thanks, Ford

tried another speaker. NO GO.
The guy said not to worry about speaker. He said the sound drove him crazy.
For my part I'd like to get it going before I give it back.

Based on your last two posts, it appears that the sound isn't working at all. We're talking apples and bowling balls here. Regardless of what's happening with the spin sound option, you should always have other sounds. If not, then forget about the switch and the spin sounds: you've got a bigger problem.

Thanks Stat. When the fuses blew it must have screwed something else up.
He said he didn't care about sound so the best might be to give it back to him without sound.
His Grandkids are who play with it & chances are they'll screw it up again.
 :259- for your help.

I gotta remember that one!

I like what Rick Dale says on American Restoration "When I restore something everything works or I am not happy or satisfied with the restoration"

I talked him into letting it here for another day to see if I can get it working.
Doesn't ding when coin goes in . No sounds @ all.
Any idea  what I should look for?
Thanks

Have another MPU to try? It would certainly make it easier to determine if it's the board or a wiring issue.

Also make sure the MPU does not have any bent pins. Make sure all plugs are seated good on the motherboard.

I don't have another S+ to try board.
I checked pins & OK.  Checked all plugs & Ok.
Sprayed contact cleaner on board pins & Volume control again - no help

Check the speaker seperately to see if it just makes a sound. Sometimes a wire may be broken in the cone of the speaker where it mates up with the main feed. Or an audio chip may be blown on the board.

I think it's on the board. You know what shape this was in when he brought it in.
You also know he does not want to put to many $'s into it.
How was your trip yesterday?

We had a great time, my friend lost 250 and I lost 35 on VP. All the VP sucked horribly at The Sands (that's where we ended up). Then we went to a friend's radio studio, he is an on air personality on the radio. I did win 50 at the Hamfest in the 2nd grand prize draw though.

I was offline for the holiday, but I'm back. :71-

Ford, did you find the problem?

Bunker, Did not find problem.
Thanks Ford

Fordsbs! My avatar is NOT a pig !!!   :30-   :200-

Anyways, have you tried to see if the MPU is sending any sound signals out to your belly glass speaker?
If not, here's a way to check...
Open the door, turn on the power and press the little white test button about 5 times or
until you see a [50] in the "Winner Paid" window...okay?

Now set your multimeter to like 200VAC and put a red lead prong onto the green wire
and the black lead of the multimeter onto the white wire anywhere near the speaker connectors.

The "Spin" button should be lit up, watching the multimeter, and pressing the "Spin" button should change the values.
IF the values on the multimeter go back to zero every time
after releasing the "Spin" button - you have a good signal going through the speaker wires.

I know you're not getting any sounds right now but this is a good test to see if you're getting sound signals through the wiring.
If you're getting the multimeter to change, then you probably just need a new speaker.
Rip any 8ohm speaker out of an old radio...it will work! 
I made a short video clip to show you how I checked for a sound signal.
It wasn't easy to do as I only have two hands...  :5- >>>

Nothing there. DEAD
PS  Good video

Hmm.....I'm now suspecting that you may have a bad, broken speaker wire...
most likely it had gotten pinched in the door hinge?
You may need to check your two speaker wires from the speaker back to the motherboard.... :37- :8- arghh!!!
That's a royal pain in the butt if you don't know which two pins it enters the motherboard.
I have to check my motherboard schematics for that answer...

The sound chip on your MPU, is it soldered to the MPU as in the 1st picture or
is it socket-ed like in the 2nd picture?.
Click on any photo to enlarge....>>>

Okay...
I just checked my motherboard schematics.
The speaker wires go to pin#30(+) and pin#20(-) on the J3 header.
Respectively,  these wires are white w/green stripe and
green w/white stripe to the motherboard.

However, on top of the MPU cage/tray where the door harness connects to the 24-pin Molex is.
(It's the largest connector on top of the MPU tray)
The speakers go into the two pins where I've outlined in the drawing below.
Again, click to enlarge if needed...>>>
 

Bunker,

What double post???

Ok I deleted it! Ha ha :200- :208-

CH :95-

BUNKER, YOUR THE MAN.  Now that I knew where to look it was a bad speaker wire.
Thanks for all the help. :279- :279- :244- :244- :259-
Ford

lol   You're very welcome Fordsbs...
I actually like questions about S+'s and troubleshooting them to try and see if we can solve problems.
Please let us know if that gets your speaker working again.
If not, then I'd have to say that it may be the MPU sound chip I posted up earlier
or perhaps something else on the MPU itself.

The motherboards are workhorses and usually nothing goes wrong with them unless
a coin slides under them and shorts the heck out of the underside of them.
That's why IGT placed those foamy pads under the motherboards so that scenario wouldn't occur.

Ran another wire & we got sound.
Thanks again. :3- :3-

aw man! I've lost the "777" in my karmas!!!!  :72-

Sorry Bunker. I didn't think of that. Should I see if I can remove it?

lol..nah..You can't anyways...I have to move on...try to help with another machine problem...lol

Good, I owed you a couple of K+'s, Bunker, so now I can start on those.  :)

I'd say there were several guys holding off on the + until I went & spoiled the 777.

Ford, make sure your customer realizes that a lot of troubleshooting and analysis went into this and that he should be more than satisfied with the repair.............that is............until.............the children get their little fangs into it again. Before you know it they will be saying stuff like "Damn, this is nothing like Vegas" "Holy Crap" and "Oh My God"  Here's an old post link to this very thing:  http://newlifegames.net/nlg/index.php?topic=4654.0

Reed, That is a good video.
The guy picked up the machine tonight & I told him keep it locked & don't give the kids the key.
I talked him into going on Ebay & getting a bunch of tokens.
He was happy & he said he might get one of the other games from me. That made me feel better.
