My Top Banana was working fine - turned it off - turned it on again - get a loud CHIME and thats all - no game.
-
Check the power LEDs on the IO board to be sure you have all the correct voltages.
Merry Christmas Barry....
-
Game has been working non-stop since first HICCUP - now the Bill Validator does not work - NO POWER - does not cycle - is the bv controlled by the main power supply?
-
Yes DBV gets +12 volts from power supply. I would replace the "inner" power supply from the pdu, it is usually the part that goes bad on these 550's. You will have to remove the PDU assembly (the one with the big red switch that controls power). Inside that PDU there's a removable 5/12v open frame power supply which is usually the culprit. The picture below is what it looks like.
Here's an e-bay listing for one.

There's also a mod that you can use to replace it with a computer ATX power supply. It is shown for the WMS4xx cabinet, but it's the same procedure for a 550. Here's a link on how to do it:

-
makes sense with the game running sometimes then not - will see about taking the power supply out.
-
I bought the power supply module off ebay - have inspected the cabinet to see how to remove the power supply - based on what I see - I have to take out the bill validator housing - maybe the transformer? I can only see one bolt on the top right of the power supply housing. Am I correct?
-
DISASTER!!! installed the module and on power up - runaway hopper!!!! no game - reinstalled original module and machine is dead - all lights the mpu board are ON. So I went from a game that had no power supply to a game that is now dead.
-
Check all connectors and re-seat I/O and CPU boards and see what you het.
Look for bent pins.
What was the part number of the power supply?
-
the part number on the replacement module "PU-110-31A" this was recommended in an earlier tread. I didn't touch the boards during the install/uninstall/reinstall process but will give it a shot - with the machine back to its original parts - all 5 lights on the mpu board are on.
-
A few questions:
1) Do you get a Bong sound at start-up? If so how many, one is good, multiple indicate an issue.
2) Does the DS1 (fail) led illuminate with the 5 voltage indicators on the right?
Attached a trouble shooting guide for your issue.
Also check all the connection to the backplane to be sure they are all seated and in the correct positions.
-
no longer the BONG sound. when I open the cage all the lights are on - will reseat the boards - to recap - the game just prior to changing out the power supply module - was working EXCEPT for the bill validator which was dead. I removed the bv housing to get at the power supply assembly - unplugged the connectors to the housing - removed the housing - swapped out the old module with the new one - reinstalled - all connectors to the power supply attached to proper positions - turned on machine and got a runaway hopper!!! - turned off machine - removed the hopper - turned back on - no gong - power to monitor - yes noticed when powering machine down. Reinstalled the ORIGINAL module - opened board door - all the led lights were lit. (i did check the fuses in the power supply back panel board as well as the fuse on the module.).
-
Wondering if there was something wrong with the replacement inner module? No Bong sound is not a good sign. Is the original inner PS back in the machine? Do you have another set of I/O and MPU board to test each independently?
-
must have been that module you mentioned on ebay - which I bought - the machine was working BEFORE I replaced the module - the module screwed up something as both modules do the exact same thing - NOTHING - no gong and all 5 led are lit on the right most board - also the bottom light is on when the machine is off . I reseated all the boards and connections - so the new module blew something. I have no boards so I am dead in the water.
-
Spin inc is usually very reliable on their parts and I've never had issues with any of their stuff. Are there any obvious signs of damage on the backplane or any of the two boards that are inside the cage?
-
did not get module from spin - you had a link to one for sale on ebay - which I bought - since the machine was working BEFORE I installed the module (and there is really no way to screw up the wiring) - OBVIOUSLY the module did something - there is no visable damage to the backplane of the power supply - fuses are good. I checked with Spin and they don't have a power supply. Don't know what damage the module did - but since the led lights are all on - there is a problem.
-
Barry, check this link, don't remember if the +20 volts shows up on the I/O board. ,anyway has alot of good info when troubleshooting power supply and the voltages.

-
so the 40x and 550 are similar?
-
didn't read the topic "550" that info was for the 40x
Jim
-
The link I posted was to spininc's listing of the low voltage power supply for the 550. I certainly have no vested interest on their listing or anybody else's listing on e-bay for that matter. If you believe my suggestion led to your current situation, it was not my intent. The biggest problem with the 550 is the lower power supply, and has been in my experience the culprit in all these types of situations both on my personal machine and others I have looked at. Since I am sensing a level of displeasure, I will respectfully bow out of this thread.
-
my apologies to Rickhunter - there were 2 sellers of the module - I didn't realize that spin had one also - guess I should have bought the one from SPIN - since my original no longer works - buying another one without knowing what damage the first did is kind of a waste of time.
-
I purchased the CORRECT power supply module from SPIN - installed and still no game ALL the led lights on the IO board are lit - there is power to the monitor - no bong sound - game is dead. What would be the most likely component to fail with an incorrect Power Supply? The fuses on the power supply back panel are good - the main fuse is good - all boards and connections are seated - no VISIBLE damage to any boards.
-
The MPU board. Do you have a 1.5 or a 1.5+? (the 1.5 has a daughter card where the vga plug is). I would just get a 1.5+ even if had a 1.5 previously. More relieable in my opinion.
-
has the daughter board - would that be the board that most likely would fail - whereas the IO board indicates no power (all the led lights are lit)?
-
It has been a while since the my 550 cabinet has run legacy, but I believe all the led lights on the I/O board should be lit? I would have to retrofit my 550 cabinet back to legacy to test. Hopefully somebody else will chime and and verify, if not, I will re-convert my 550 back to legacy to see what it list and what is not. If the power module had the wrong voltages (i.e. 12 volts where 5 volts should have been), it would have blown the mpu board for sure. I would try that first.
-
i read somewhere that there are VOLTAGE lights and a FAIL light - with the voltage indicating voltages are good - obviously the FAIL means problem. So with ALL the led lit - I assume I have all the voltages BUT something? FAILED. I see the IO boards are available for a reasonable amount - do I TRY that first or is the FAIL an indication the MPU is as fault.
-
Hoppers are usually 24 volt. When you power on the game do you get lights as well? Is the BV still not getting power? What about any power LEDS on the backplane?
-

So with ALL the led lit - I assume I have all the voltages BUT something? FAILED. I see the IO boards are available for a reasonable amount - do I TRY that first or is the FAIL an indication the MPU is as fault.
I don't believe the Fail light would report the MPU, but only the I/O board. I would just get a set of I/O and MPU board, always good to have spares, especially in these older platforms.
-
would like to try to narrow down the problem - buying boards not knowing if they are good as well - just would like to see what the led lights are telling me.
-
Hopefully somebody who has an active 550 machine will chime in. If not, I will convert mine back. It's been like 6 years since I've run a legacy game on my cabinet since I switched to CPUNXT.
-
i appreciate your offer - but lets see if someone chimes in - save you all that work - and me spending money for nothing.
-
See if this helps any.
Not for your particular error, but then again.
Check and re-seat all PLCC chips and check for properly seated EPROMs
See PM
-
got my boards repaired by SPIN - now I get the chime and message "invalid ram clear" ?
-
Did you clear the game after you got the boards back? Check voltage on the battery.
-
how do i clear? chip? battery is good.
-
Yes, you need a clear chip. I'm not sure if the universal clear works for non 1.5+ boards. You will need one with the denomination you are using as that is how it worked originally. What denom do you have on your cabinet?
-
i think i have a clear chip in my files - need to bring up my pc and check - I have some clear instructions - says for model 40x - mentions an xu2 - my game is 5c. My game is the 1.5 has the daughter board.
-
If memory serves me right XU3 is where the clear goes. Someone else can verify this for us, but I'm 99% sure it is XU3 as some of my 550 mpu's actually came with a zif socket in XU3.
-
Did Spin say if they found problems with both boards or just one?
-
I need a multi denomination clear chip for williams video - i have one but it is for the slot.
-
got a multi-denomination clear chip as recommended by tech at SPIN - copies onto a 27c080 eprom (cksum d04f) - installed and "SECURE MEMORY FAILURE" put game chip back and no gong.
-
That's why I believed that the MD clear chip was not compatible with your board type. Try using a clear chip that is just the denomination you need.
-
Spin tech said I needed the multi-denomination clear - which is what I tried - not sure if it was the right one?? provided by a trusted member.
-
What is the checksum of the one you used?
-
CKSUM - D04F
-
Also looking over my notes a Secure memory error is also tied up with the eeprom at XU27. I would try the single denom clear first just to rule that suspicion out of the way. If it doesn't work, I would replace the XU27 eeprom, which is socketed so an easy replacement.
Your checksum is correct for the MD universal clear.
-
27C080 if that is your ?
-
Sorry, chrome font error, I re-did message above.
-
thank you for all your help - the board was fixed by SPIN so i would have thought that eeprom would have been checked - will give it a try tomorrow.
-
well there is no prom in XU27 - and I do not get the GONG anymore - plus only 2 lights are lit on the IO board.
-
Well, I guess at this point it depends on how much money you want to sink into the cabinet. I would look for a backplane before I would try anything else. If the boards were fixed by Spin inc, the only thing left to try would be the backplane. The eeprom can also be found on U26 on some boards, have you downloaded the wms550 service manual from the download area? There's a lot of good info there.
-
I think I am done. cpu io and power supply - enough is enough - thank you for all your help
-
Clear chip is a ST 27C801 and installs in XU-3 .. beware, if you put a 27C801 in backwards and power up.... throw it away.
XU-27 is usually empty except for Key operations
Putting a 12 volt power supply in the bottom cabinet should have only damaged the I/O board
-
I was told to use an 8meg so I got amd 27c080 - I did installed in xu3 - got the gong - and the error message - when I put the game chip back in - no gong and only 2 lights on the io board are lit.
-
I would be glad to supply a working clear chip. ST 27C801 is correct blank...
-
i appreciate that
-
FINALLY - after 1000s of hours and dollars (seems like it anyway) with repairs by SPIN - the GAME is running EXCEPT for the BV - will close out this thread and open another for the BV issue. thank you all for the help
-
BACK AT IT AGAIN!!!! the game runs except for the BV. Game has a wba11/12 ss transport/head that WAS WORKING prior to board issues. SPIN has repaired the power supply, io, cpu AND checked out the bv. Using the universal clear - there is no mention of a BV only the COIN HANDLING. There was a daughter board attached to the transport that SPIN told me to remove and reconnect wiring in the transport (done) and they provided another board that mates with the wiring going into the transport. When I go into diagnostics - it tells me I have a JCM145!!! BV does not cycle or lightup. How does the game recognize the BV??
-
The 55x platform requires an RS-232 interface for the validator. WMS did it two ways depending on how old the machine is. One way was using the side mounted daughterboard on the validator itself. The other way involved an RS-232 interface that was mounted on the rear of the validator cage and was in-line between the dbv harness out of the backplane and the dbv itself. This little board was made by WMS. If you don't have this board behind the validator cage, you need the side mounted daughtercard. If you have the board behind the validator cage, you need to remove the side mounted daughter card.
below is a photo of the board that is mounted behind the validator cage.
Also if the validator is a WBA-11, you can remove the eprom and put one for an S+ and tested there if you have an S+ equipped with a WBA 11. This will insure that the validator works. The next step would be to troubleshoot the RS-232 board, whichever type you have.
-
that is what i did - i removed the daughter board from the transport and added the board you pictured to the back to the housing - using the existing wiring. I did the clear but find no mention on setting up the BV - does not power up during startup.
I will try the eprom also another transport. The existing unit was serviced by SPIN so i ASSUMED it was okay. I got that board you pictured from SPIN as well.
-
It's been a while since I cleared and setup a 550 since my machine was updated to CPUNXT. I will need to go and convert it back to get a reminder on what happens, but I don't think the dbv is setup during the clear procedure, it was only used to select the comparitor and the denomination of the machine. But I'm not 100% sure on this as it has been at least 3 years since I did it last. I'll try it if you can't get any further, just to verify all the steps.
-
will try other transport and play around with the software. I did notice the board that I got from SPIN did have an X on the back (not usually a good sign)
-
tried another transport/head from a S+ - voila - powered/cycled but did not work. I contacted SPIN and they are going to send me another BV setup and tested to work in my machine. These guys are great.
-
It's probably that litte serial board PCB with the "X" on it.
-
NO PROGRESS - replaced the BILL VALIDATOR with a tested unit and the "daughter board" all provided by SPIN. BV does NOT cycle. Game still thinks it has a JCM 145/146 (the initial bv unit had a special daughter board that made it look like a jcm145) and that unit WORKED prior to game failure mentioned in original post. To refresh - game was working - power including the bv - POWER SUPPLY replaced - then CPU and IO sent in to SPIN for repair - GAME gamed up BUT no bv - replaced the jcm daughter board mounted to the side of the transport - reconnected wiring on the transport - and that is where we are - everything works EXCEPT the BV.
I can not find how the game recognizes what BV is attached - the clear chip and setup only allows what cc and coin - nothing about the bv. The diagnostics shows that it thinks it has a JCM145 when in fact it has a wba13
One thing that stands out in the diagnostics (see screen print) is jumpers? can there be jumpers on the cpu/io that indicate the BV?
-
I will convert my machine back to a legacy system this weekend to help you troubleshoot. If I remember correctly the jumpers were used to set jurisdiction.
-
The manual mentions that Jumper #1 is for jurisdiction and Jumper #2 is for Bonus setup. It also talks about getting into the Technician Menu System to select which bills you want the machine to accept but I didn't see anything about selecting which type of bill validator is installed or how the machine determines the BV type.
-
the only thing I can think is that the power supply may be no good? since the bv transport is not cycling - the connection to the p/s is good - but???
-
Is there a little red light on the side of the transport that indicates it is getting power? I will do the conversion tonight, and observe the whole dbv procedure then report back.
-
there are the 2 lights on the bill head that are on.
-
Ok, I finished the conversion. It is cool to see that #1, everything still works, #2 eprom based games boot really fast!
You in fact, have a newer release of the game than I do.
Ok, so I ran the clear. The only thing I chose in the clear was the comparitor type and the coin denomination. The system automatically knew it was USA based on the switches of the I/O board.
After I ran the clear I got a ram clear tilt, which I cleared by pushing reset button (or was it turning the reset key?) I did both. I forget which one triggered it.
After the tilt cleared, got a black screen, then it said loading graphics, at which point the validator cycled (this was the only time it cycled, never during the clear). The game came up and was ready to play. I went into the version screen and this is what I got. At no point did I select the validator type, it just auto-configured it. I'm also enclosing a photo of the rear RS-232 validator board.
The connection closest to the cabinet wall is the one that goes to the backplane. Incidentally that harness has a molex pigtail with a pair of wires that plugs right into the PDU for 12v power. The other molex connected to the RS-232 board goes into the validator plug harness. I would also note that my validator is a WBA 12.
-
thank you very much for all you work - the only difference I see is in the wiring going to the rs-232 board - all the steps you took are exactly what i did regarding the clear and setup. Will load pics of my board and wiring later.
-
here is my wiring with some extra wires that I don't know where they go.
-
still no bv - sending ALL my boards to SPIN - the bv the power supply - the boards including backboard. The only only question i have is the are wires go to the bv door switch - that need to find where the actually go - there is a black/purple? black/yellow then a black and a yellow wire.
-
took a LONG TIME - thank you to RICKHUNTER for going the extra yard on this one - SPIN - FINALLY!!! - fixed the problem - the IO board again. Anyway - it's up for sale - I will never recover what I have into in in time and money - but I just don't like giving up.
