Just got a CEI Casino Poker and it has problems. I pulled out the main board and sprayed contact cleaner on the board contacts and cleaned them. Put the board back in and still didn't work properly. The main board say it is a 906 111 Turbo + gameboard. Side tag says M - 4492, DOM 4-3-91. The hold cancel buttons on the front allow moving around within some of the menu functions. It will just randomly take off and go to anther screen on it's own. The video has a problem. The micro switch buttons inside, menu, hand pay, error reset are very sticky and not sure if they function properly. Not sure if the mother board is causing the bad video or if both the video and mother board have problems. Visually examining the boards there doesn't appear to be any glaring problems with components. Looking for some help on where to begin. I have another CEI Casino Poker working but it has a 904 gameboard. Don't have another working machine like this to swap boards out with. Attaching some pictures. If someone can be of assistance I would appreciate it. Thanks

We're you the person looking for the door latch for the CEI about a year ago? I finally found my spare door with the lock and latching lever. I do have a few CEI parts but no 906 boards..

Yah, that's me. Need the door latch mechanism that slides up and down and other related parts. Bought this machine originally to cannibalize but now decided to see if I can get it running. What exactly do you have?
-
While you're waiting for those parts, I'd carefully clean each one of those sticky switches. That might explain any jumping around especially if they're making intermittent contact, when you don't want them to!
-
A lot of these poker machines will not operate correctly if the buttons stick. That the first thing I check and repair.

Yah, that's me. Need the door latch mechanism that slides up and down and other related parts. Bought this machine originally to cannibalize but now decided to see if I can get it running. What exactly do you have?
I pretty much have a complete door. It has the sliding latch, and mounting hardware for it. I think its missing one screw and guide bushing, but the other parts hold it secure. I believe it has the door lock with cam and key if I have not miss placed that.
-
I have a background in electronics. On my other CEI machine (904) the little micro switches move freely in and out. They appear to be momentary contact switches that are spring loaded underneath the larger red buttons. I have never attempted to clean one before just replaced them. These seem not to operate at all, sort of froze in position, Good point, that is why my function seems to randomly jump around. I'll open up the box they are mounted in remove them and attempt to get them working. Spray some contact cleaner on them? Then test them for proper operation. Are these just single pole momentary contact switches? Thanks for the tip.
-
The switches are standard NO/NC with the common tab.. What needs to be addressed are the buttons them self not the switches.. You need to take then apart and clean the dirt, pop, and other nasty stuff that gots inside between the button and housing. I usually take them apart and soak them in a hot water bath with the cleaner of your choice. A tooth brush and Q-Tips works wonders to clean them.
-
As posted the 3 micro switches are 3 pin normally open, normally closed. Only uses the normally open pins. Unsoldered and removed the 3 switches. Menu was stuck in on position, hand pay was stuck in off position and error reset sort of worked. Shot some contact cleaner down around the shaft of the switches didn't do much. So put a couple of shots of WD-40 down around the shafts and worked the switch. That did the trick, checked them for continuity and they work great. Have not put them back in yet. Will post after I do. Never worked on one of these machines before. Again thanks for the tip.
-
Put 3 micro switches back in machine. Prior to cleaning and getting the switches working again, had different video screens randomly appear including the menu screens occasionally, along with hold/cancel buttons lighting up.
Now I have 3 different video screens in a repeating endless loop. (attached are photos) Not sure how to access the menu functions with buttons on front of machine.
Is this possibly the normal mode for the machine when sitting idle waiting for someone to play it? Without any credits on the machine and now ready to accept coins or bills? (the video in all the screens clearly has some issues and needs to be repaired). It has a bill acceptor and quarter slot. Neither will add credits when bill is put in, coins just drop out into the tray. Is my only problem now (besides the video) is to somehow get credits on the machine? Any suggestions on how to get credits on machine, if that is my problem at this point?
-
You need to make your picture pixels smaller to post here.. It sounds like you might have a stuck test or menu button inside the machine..
-
Attached is a picture of my working 904. No credits, it displays last hand played and flashes insert coin, waiting for the next player. That is what this non-working 906 should like also? Thanks.
-
Looking for any information, manuals, for CEI 906 lll Turbo +
-
There shouldn't be any "weirdness" in idle mode.
Have you checked to make sure all the chips are properly seated in the MPU board?? Seems like I'm posting this everywhere but it's been an issue on many occasions.
If all else fails, I have a spare tested/working 906 III turbo board. PM me if you're interested.
-
The 906 should look similar but the main menu will list available games. It should look something like this (other than "mux error").
Were you able to check your connections and IC's?
-
In idle position looks like last hand played. I attached previously, above are 3 different video screens which currently repeat in an endless loop on mine. Won't be able to reseat the IC chips for a few days, my 4 grandkids are here for the weekend. The IC chip contacts can lose continuity over years of time similar closed relay contacts on a pinball machine. I'll carefully remove them and clean the contacts on the chips and the sockets as best as possible then reseat them. Thanks for input.
-
Have fun with the grandkids! Don't let them wear you out!
Let us know what you find out with the chips.
-
Sorry about the delay from last post. Decided to order IC tweezers online for 96 cents from China, weeks to arrive. Didn't want to chance using a screw driver and damaging the IC chips or sockets or possibly breaking the brittle circuit board.
One at a time removed and reseated all the large chips, did not remove the small chips, probably are power supply related and that worked. Put the board back in and turned on the power. The machine came up with good video and 5 function options. The IC chips contacts after sitting in the sockets for decades have oxidized just removing them and putting them back in cleaned them enough to make contact. My thanks to the suggestion on this thread for reseating them. I tried the 5 functions entering them by pressing the last 2 buttons on the machine. When I got into the last one I think "birth of game" it went into a diagnostics? and then said to press menu? The went to opening screen and I put in 5 quarters, dealt hand, saved a king and got 2 more for 3 and it gave me 15 credits. So it seems to work fine. My wife is now playing it feeding in quarters and has 435 credits on it. The horizontal and vertical size are a little large, I assume there are thumb wheel adjustments for that.
Is there any printed information available or can someone let me know how to make adjustments in the menu screens with the hold/cancel buttons? My other CEI will not allow you to continue putting in quarters when you have credits they must be played. I assume it is an adjustment. My IGT stops at 1,000 credits. Photo of machine attached.
-
Again thanks to Shortrackskater who suggested I reseat the IC chips.
-
Good job on getting it running. Flaky connections on decades-old sockets can definitely cause a problem. Besides reseating the chips sometimes the ic legs can be carefully cleaned with a soft pencil eraser to remove the oxidation on them. This is a delicate task, don't want to bend or break the ic leg. I try to make a backup copy of the eprom or at least the .bin file before doing this, just in case.
There are quite a few manuals and documents for the Cal Omega/CEI machines in the NLG library but I don't know if any of them are for your particular machine. Manuals for this slot machine are sometimes of a general nature and don't always have all the details you'd like to have. To access the NLG library I think you'd need to make a contribution, big or small, to the NLG website. But in my opinion it is worth it for all the help and support the kind and knowledgeable people here provide, even if you don't get anything from the library.

Also, coinslots.com has a lot of manuals for older machines:

Machine is working fine. My wife worked it up to 1,000 credits and the hopper is now paying out wins. I would like to change the background screen color to blue from red. I assume I can do that through the menu button? Anyone know which function to enter? Have attached a screen shot. To the left of the 2 of spades it says MUX ERROR. Doesn't seem to affect the functionality as far as I can tell. What exactly is this?
-
I'm not too familiar with Cal Omega/CEI machines, so take this as a guess.
A MUX is shorthand for "multiplexer", an electronic circuit that brings all the machine switches connections into the mpu board processor. On powerup the machine does a selftest, checks memory and other stuff, plus scans all the switches to see if they are in the normal position. The MUX tells the mpu when a player has pressed a button, like hold a card or discard a card, or to select certain menu choices. If your game is playing fine then there may be a bad switch being detected that isn't a player pushbutton switch but is some other switch. If you can find the manual or someone knowledgeable on your machine that could help find out what is behind the MUX error.
Can you post more photos of your machine showing the mpu board and software eproms with labels, also the entire front of the machine and its nametag and the interior of the machine? This would help someone to identify it.

Here are more photos

Photos of the board

Thanks for the clear photos, that is a good-looking machine. There are a few folks with Cal Omega/CEI experience here on NLG, hopefully they will be able to help with your questions. That dipswitch on your mpu board probably sets certain features or options, like enable/disable the Double-Up feature, hopper limit, etc. One of the dipswitches may turn on diagnostic mode and you could then look at the diag menu to see what choices you have.
The labels on your game eproms should id the game software to help pin down what options & features you have. I don't know how to change the screen color from red to blue, or if it is possible, it may be the way it is for the particular game software you have. If you have other game eproms you can change them out to see if it changes to blue with them.
I read thru this thread but may have missed it, have you checked the mpu battery and replaced it if needed?
On the MUX error you have, I read an old discussion thread that said some Cal Omega/CEI machines used a spare MUX channel to connect the machine to the casino network, for stuff like player tracking. If the extra equipment to do that is not installed and the machine is looking for that network connection then the MUX error could happen. I can't confirm that, it is only something I read.

This may help!
I had this exact issue when I plugged in a 906 turbo board in my CEI that is wired for a 904 board. Here are some highlights and a link to my post.
From SolidSilver:
"I just remembered that MUX is Omega's (and many others') term for MultiPlex, ie: connection to- or through- another computer via some interconnection scheme. And that on their final boards (906 III & up) they offered casinos the ability to hook up a CEI video slot to their in-house information tracking system.
They did this by installing, (wait for it.....) an optional MUX board!
Your machine, in which you are trying out this board, probably does not have a MUX board; but the board (and/or eprom game-set software) is configured for it.
With this remembrance in mind, and another glass of wine in hand, I did a search on the old NLG site. Here is a link to one in which the hapless CEI owner has a MUX error. And guess what: it's on a Gamblers Choice!
http://newlifegames.net/nlg/index.php?topic=15592.msg133504#msg133504 (http://newlifegames.net/nlg/index.php?topic=15592.msg133504#msg133504)"
From Badbaud:
"Sounds like you are trying to put a 906 Turbo into a machine wired for a 904 board. The turbo machine has a keypad next to the standard player buttons and a MUX board inside powered by a separate 12V power supply."
Finally... here's a link to the entire thread.
http://newlifegames.com/nlg/index.php?topic=4642.0 (http://newlifegames.com/nlg/index.php?topic=4642.0)
So, to me, it looks like you have a later version of the MPU board, in your machine. Depending on the game or games, they can work just fine. If you had a blackjack game, the single panel of buttons would only work for some parts of the game and not others, since the second row of buttons isn't there.
As for the colors... hang on.
-
For your colors... there's three potentiometers on your MPU board marked: R G B
I'd just play with them until you get the colors you like.
-
As you can see from the photo got the background color adjusted. Thanks. Found pressing the stand button brings up the Gamblers Series game selection. Bonus Royal, Roarin' Fours, Deuces Wild, 4 way Bonus and Double 4 way Bonus.
Only issue is I would like to reduce the horizontal screen just a little. But the horizontal thumb wheel doesn't function. All the others do but not the horizontal. Is there another adjustment that can be made?
-
Oh someone asked if I tested the battery. Did not since it held credits when turned off, which I assume is it's function? Did notice it had a tie wrap which was cut through, so may be has been changed in the past?
-
This game will function without a battery. As you suspect a battery is needed to remember credit, date time book keeping options etc. All game options are set through extended menu learn pages. SW1 DIP switch doesn't do anything. SW2 controls paytable if you remove the header from its socket you would have a 5-8 paytable.
-
Well I'm back to the same problem it originally had. Video is trashed and just in an endless loop of 2 screens fading to the background blue color between each for about 3 seconds. 2 screen pics attached. Removed the main board, removed and reseated the large IC chips. Same problem after numerous tries. So the quick fix didn't last. Anyone out there that works on 906 III turbo boards, has substitute spares parts?
-
Yes and yes. Hang on...
Double check all the "socketed" IC's and also pull the MPU out and make sure the contacts are clean on the PC board and the back, where it plugs in.
I'm sending a message to another NLG member who may have more information for you.
-
Removed and reseated every ic chips on the board. Still doesn't work right. Pressed the menu button and I think it is now locked in one of the menu functions, birth of game? Even though the video is distorted, in lower right corner looks like it says: call attendant, press hold to exit. (attached pic) menu, hand pay, error reset buttons don't anything. The stand button is flashing and holding down any combination of hold buttons doesn't do any thing. Not sure how to proceed, stuck.
-
I messaged another nlg member but haven't heard back from him. There's only a few left here that know CEI stuff and one is seriously ill right now.
It concerns me that you got a different "scrambling" on the screen after you reseated the chips. Are you sure there isn't a bent or broken leg on one of the IC's?
And are you sure the MPU is shoved in to the plug? Sometimes you have to push quite firmly.
I'll dig into my manual when I get home and see if there's a reset procedure. It's been so long I don't remember.
-
I have heard of people using a cold freeze spray on the boards components to track down bad solder connections or IC socket problems. I'm not 100% sure what they use, but you spray the boards and watch the screen to see if it changes. I've always wanted to buy a can or two to have. Maybe someone will chime in on what's used?

Just to keep my saga going with this machine. I turned it on tonight and it's locked in the what looks like the main menu mode, since the video is so scrambled hard to tell. Now it occasionally will spit out 4 or 5 quarters from the hopper and makes a weird sizzling sound like bacon frying. Additionally makes a loud snapping sound like an arcing with the monitor shutting down and coming right back up. No components seem to be overheating or burning up. The arcing may be high voltage of monitor? So shut it off.
-
Looks like I'm going be getting more involved with it. Pulled out the game board and hopper, turned on the machine. Noticed the arcing, on the 911 motherboard. It arced about every 4 or 5 seconds. (was able to get a picture see attached). Arcs in the lower right hand corner, from a component solder hole to a circuit board track. So I cleaned that spot, turned it back on and off a few times and let it run. Arcing stopped. All the boards are all pretty dusty, may be a build up of dust? Or bad capacitor discharging not holding a charge? Put the game board back in and video is still scrambled but can access the various menus and hold lights are back on. Picture attached of current video screen. Motherboard looks like just a number of connecting points and a regulated power supply with transistors heat sinks, capacitors and diodes? Not sure of all the voltages, assume 5 volts, 12 and is there 50? (I see a coil on the back of the front door). Looks like my plan now is to pull the motherboard get it on my bench and replace all the large capacitors. Does anyone have some documentation on this machine?
-
Removed the mother board and replaced the 3 large caps. Getting the mother board in and out of the machine was a chore with all the connections and tight space. Put it back in this morning, turned it on and it wasn't arcing as before or noise on monitor screen. So that may have solved one of the problems, bad cap discharging? Have sent out the gameboard to be analyzed and or repaired. To be continued.
-
Who's checking the game board for yea?
-
Got my game board back today. An IC chip in the video circuitry went south and was replaced. Put the board in and the machine came right up. Good as new. My wife is building up the credits right now on the machine. Don't know if my replacing of the 3 large caps on the mother board also helped. But I do not have any arcing as previously stated. It's always good to replace old caps anyway just to eliminate future problems in advance. Thanks for all the help and suggestions from everyone. We have 2 other video poker machines (one is never enough) an IGT PE Plus and CEI 904. This machine is our favorite. Kind of crazy I have a video poker program on my I-pad but for some reason nothing beats playing with quarters on a real casino machine.

Who did the board repair? Did you send it to K-Lar or to Dormi?
-
Good job on sticking with it,
glad to hear you got it working ! :cool_thumb_up:
