Last time I fired up the machine I had no sound from any speaker, so I tried turning it off and on again and the sound came back. Today I turned it on and again no sound, I tried turning it on and off and NO sound.
So, I pulled out the little sound amp from above the 5th reel and I think it visually looks OK. I also checked the sound in/out harnesses on the board and they are fully connected. I didn't see any burns or signs of a short anywhere. The machine displays no tilts and operates fine other than no sounds.
So, anyone have any suggestions? I'm wondering if perhaps the sound amp may be bad since it seemed to be intermittently working last time I played the machine. Is this a part that commonly needs replacement? I'm unsure how to proceed. Thanks,

I have seen some issues simular to your concern. It was the amp board. Not jumping out and condeming it but what I have seen. It helps to have another "canidate" sitting around to verify (part swap/black box diag.). Look at your back plane also. The amp boards get hot that is why they have a big heat sink on them and a big red label that says-HOT!. Try this-Just one time-slide it out and put in the freezer for about 10 min. put it back in and try it. Sounds crazy-huh- :arrowthruhead: .

If you have another amp try swapping them.
Good idea Sizz
-
I own only one Alpha and only have an extra ticket printer and a spin button in the way of extra parts, so no swapping available :no: . I'm willing to try the amp in the freezer but when I pulled it out I felt no heat at all, which thinking about that maybe suggests it is bad because if it was doing something it should have been at least warm right? :Scratch-Head:

It will not hurt it. I know what they say about electronics and componets. This would determine and some times it works some times not being how bad th internal blow is of a cap. Contraction.

I put it in the freezer a few minutes ago and will give it a try shortly.

Also... This is just a FYI . The lower speaker on a alpha s-9, and some others has issues. From the door being open and closed in the casino by slot techs,etc. that don't give a sheet-slam these things. The lwr speaker magnet will come off and stick to the metal plate behind it and other items, copper wires from the coil hanging etc. The lwr speaker in my opinion fails quite often due to this and after even home users get them . May have just been a wimpy build on those. This is however not your prob. You still have upper speakers which hardly ever fail -was just a fyi in the bally alpha thread here!.

Well I had it in there for a solid 20 minutes or so, it was pretty cold. Still no sound though.

Good to know, I just checked that speaker wire down there was out of any pinch points. I'm thinking I could try a new sound board and see if it works, if not, I'll have a spare.

Prob is the amp board air bal. Did you look at the backplane/reeldriver board behind it yet. I have seen some get hot spots in them causing a continutity problem-Still leaning on a sound amp though. Another member had to get one a while back and got one from rudy. I cannot sell for those prices as my stuff is new and don't bother. I cannot remember the exact game you have -What is it?. just a reel video-s-9?.

The wires were not the problem the whole magnet comes off the back of the speaker and strews copper wires and debris everywhere!.

Here's a picture of the machine. My understanding is that it's a S9000, but feel free to tell me if I have it wrong. I did look at the backplane behind it where the audio in and out wires connect and didn't see anything that looked like it would be trouble. Really on the whole board itself it appears fine to my eyes, I'm certainly no expert but I didn't see any burns or discoloration...things like that.

Yes sir-S-9. Get another audio amp board and try it. On these things that is a good spare part to have and the lower pwr. supplies 12/24v. You ,myself and others have to keep in mind these things sat in casinos on 24/7 so things do fail as all things will evintually over time-No slot machine is any diff. or--for that matter--people!. Let us know when You try the part. - :cool_thumb_up:

yeah, I'm going to try a new amp board. Also, I will keep on eye for exploding speakers down in the belly. Truthfully though I kind of wish this was my problem because that's easy to diagnose. :fever: ;D
-
I agree there balancer BUT if it were easy it would not be fun---- :th_Smiley-bbq: .

Funny you say that because I suppose that tinkering around with machines is fun, however, I like tinkering around in an upgrade kind of way rather than a lets get it back to normal way. That said, this is my first real problem since I started buying machines and (jinxing myself ;) ) I know it won't be the last. Thanks for your thoughts and tips, much appreciated.

And I'm sure that's not the first, or the last time we will hear a diagnosis like that from you B.... :Tongue_Out: :Tongue_Out:

Upgrading and expanding as far as the slot world is what it is all about. It is very hard to stay ontop of the latest curve from the big 3 and then some. Most of the time their latest curve on new stuff is we are on their last curve as far as tech. and games. The games are becoming more tech. and involved in Bally,wms,igt,etc. but, There are fun-certain ones that will always keep all our interests. Off topic here on your post/thread-sorry. All this other will come up soon. Good thing we have some great members here on the diff. platforms.

Well you think that is something-actually it does work. Now Have you ever heard of anyone washing mpu/cpu boards in a dishwasher?-If so what is your thoughts? Some triva back at ya--- :Tongue_Out:
-
I know for a FACT (well, like "Read it on the Internet, so it must be true, FACT") that ONE of our BELOVED members has indeed washed MPUs in the dishwasher...and was SUCCESSFUL!!!! Old site, either Coors or Cowboy, I believe, but I'm leaning towards Coors...

Roz, I have something to say about that. We need to not discuss this here further as this thread has been hi-jacked. I am to blame for this. Much appoligies Air-balancer. We will continue another rant somewhere else. No one has issued a warning etc., I am issuing my own.
-
I have no problem with a hi-jack. Also, I have many other kitchen appliances available if need be. :24:
-
What is your status on this problem Airbalancer?. :Scratch-Head:
-
I'm still waiting for a replacement sound amp board to arrive in the mail. I'll be sure to update this topic when it gets here.
-
I'm sad to report that I installed the new sound board and still have no sound. :Scratch-Head:
Looks like I get to dive into this one a little more thoroughly now.
-

Remove the amp board. Take a flash light and shine it on the backplane that the amp board plugs into. I think it is a resistor (not my book of worms) that burns and will leave burn marks that look like a pair of wings (above the resistor).
-
Here are some pictures of the sound board removed and looking back to the backplane where it plugs in, and just below. I'm wondering if I should just do a clear and set it up again and see if that does anything. :Scratch-Head:

It would be where C39 is or the one below. It is not burnt and should be okay. I have only seen it once before so I am not sure which one it was. I know this is a dumb question but have you checked the volume setting?
-
I appreciate your thoughts on this. I have taken the audio settings up to ten and hear absolutely nothing. Even on a start-up I don't get the couple or three beeps that should happen while it boots.
-
This may be old news, from looking at the post dates on this topic....
But be sure to check your 24VDC line. The sound amp assembly has it's own regulating circuit which will "drop out" power to the amplifier IC if the incoming voltage gets too low. This prevents components from catching fire due to overheating (high amp draw) from cold solder joints and oxidized/poor connections, etc.
The 24VDC output of the "big metal box" power supply is shared by the stepper (reel) motors, sound amp, and light tube ballasts. Issues with any of those causing your voltage to drop (excessive load) would be where to look if your replacement amp assembly doesn't fix your problem.
FYI: simply unplug he INPUT connector at your light ballasts to eliminate the load from them. One OTHER thing to do, is to eliminate the possibility of a MPU output failure: Take your desktop computer speaker system, and plug it into the GREEN "audio out" plug of your slots MPU. If you now have sound through your computer speakers, that will confirm you have an audio amp OUTPUT problem and not an Amp INPUT issue from the Slot "brain box".
Hope this helps....

I plugged in some computer speakers I have and heard the game sounds. Then after plugging the machines audio cable back in... I'll be damned, the thing started making sounds again! I'm guessing the plug just needed a little adjustment? :duh:
I'm thinking back to the old Walkman days having to sometimes spin the plug on your headphones to get the sound to work. In any case it looks to be back to normal!
Thanks FireBallJackpot for the tip! :1:
-
Excellent!. Also good job fireball. Now balancer, As easy as that jack/connector is to get to I would have figured you would have unplugged it and plugged back in--- :arrowthruhead: . Mark as topic solved-? I say yes. And at least you got yourself a spare amp board now---for when-- :burningresistor: .
-
The funny part is that I did indeed unplug it and plug it back in. I'm guessing since I tried the speakers it made me leave the jack dangling so when I put it back in it went in a little different and rotated? I have no idea, but it works so I'm happy.
Edited to add: I have marked this "topic solved"

:cool_thumb_up: , The end result is always a happy slot owner!. I had give ole fireball a :1: also earlier. What the site is about-People working together when needed and pulling resources to resolve problems etc. Also, Look at how much more you know about your machine now balancer!.

Yep, I love this place. Thanks guys.

No Problemo. :nerd:
You have an "oxidized" audio plug (and port). Alas, the port is not accessible for cleaning, but you can use an alcohol wipe to clean the male plug, if the problem persists.
Kinda like the old days when the volume knob on your stereo "crackled" when you rotated the knob. Oh, by the way, DO NOT use any spray "cleaners" on the port. You will do more harm, than good. Spray cleaners have an oil lubricant which is designed for potentiometers and not signal jacks.
:homer_crawl: :donut: Mmmmm... Donuts!!

I am working in a casino that had a flood and the machines were under 2 metres of water for a week. When the water receded the boards were covered in thick mud and were stored for 6 months. When I came here I washed cpu boards in the sink and all the game software. So far I got 2 IGT Cleopatras working and used other games, boards and glasses for conversions.
-
Kennyb - may I suggest you start a new sptopic for your "flood machines"? Some of us have knowledge on that topic, so it may be worth your time.
