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?

GOS · « **Reply #8 on:** January 03, 2016, 02:38:00 PM »

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.

Neonkiss · « **Reply #9 on:** January 03, 2016, 07:57:40 PM »

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.

GOS · « **Reply #10 on:** January 04, 2016, 12:05:08 AM »

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.).

rickhunter · « **Reply #11 on:** January 04, 2016, 08:49:44 AM »

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?

GOS · « **Reply #12 on:** January 04, 2016, 11:08:25 AM »

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.

rickhunter · « **Reply #13 on:** January 04, 2016, 12:04:31 PM »

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?

GOS · « **Reply #14 on:** January 04, 2016, 02:40:50 PM »

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?

Jim · « **Reply #17 on:** January 04, 2016, 03:40:20 PM »

didn't read the topic "550" that info was for the 40x

Jim

rickhunter · « **Reply #18 on:** January 04, 2016, 05:45:26 PM »

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.

GOS · « **Reply #19 on:** January 04, 2016, 09:37:09 PM »

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.
