Fixing Pump It Up Foot PCB: An adventure in electrical engineering

- My player 2 pad has had three of its panel lights out since I got the machine. Here's the process of diagnosing and fixing the problem. Huge thanks to ForestCat_Peter for helping guide me through this!
Forgot to mention here, but your video helped me figuring out the problem I was facing with both of my FootPCBs. After more than a year having problems with the LEDs, I was able to fix it by resoldering a IC with cold welding :)
15:10 There is a tool called IC puller or chip extractor which is designed to pull ICs from a circuit board instead of screwdriver. Also before replacing a chip, solder a socket in its place and put the chip into that socket. If it breaks again or if your replacement doesn't work, it's much easier to replace it again (or to put the original IC back in).
You did a good job with the soldering. Great to see it all working now!
I love your videos, man! I can feel you really love what you're doing and that makes it really good to watch, besides I'm learning a lot from you. Keep it going!
This gives me hope that I can replace a resistor or voltage regulator on my board to get a light working. 7 out of 8 work, just the player 2 up arrow panel doesn’t light on my extreme cab. I get a REALLY small voltage across the pins that are supposed to power it on the board instead of the necessary 12v. Time to dive in! I guess any advice is appreciated if you’ve learned anything since uploading this video. Thanks for all the time you put into your videos- they’ve been very helpful.
Fist off, you did a good job on the fix. You worked out on your own a lot of the little details that most people have to learn from other people. The scorching on the board is do to a fundamental but unintuitive property of soldering. The board, the glue that holds the traces on, and the chips them selves are all destroyed at a much lower temperature then solder melts at. If you use a soldering iron that is cold enough to not hurt the board, then the solder will never melt. If you use a soldering iron that is just hot enough to melt solder then the traces and pins will conduct the heat away quickly enough that you will burn every thing near by before the solder melts. You need the iron to be hot enough( 650F ish) so it melts the solder before the surrounding area can get hot. In the video it looks like your iron starts off hot enough but it cools off as you do too many pins in a row. Just pause for a few seconds between pins and it will heat up preventing the scorching and reduce the lifting of the traces( it's a cheap board with cheap glue so damage is hard to avoid). Solder suckers are good and getting large amounts of solder, but bad at small amounts. Solder braid is the other way round, it's really good at grabbing the last little bits. So start with the sucker, then finish with the braid. Lastly if you know a chip is bad, then you can just cut the pins and save your self lots of time.
Now that I think more about it, it's also possible that you didn't scorch the board and what you are seeing is flux residue( I have made this mistake myself a few times). In which case a soft brush with some alcohol will clean it up.
Fascinating, thanks for the info!
Our pads have a problem seems like it's grounded or something.
I have some question about convert the cabinet to pc, what voltage receive the monitor board? 220 v or 110v? on the manual the block diagram indicate 220v, is that so?
SOME VIDEO OF HOW TO REPAIR A MK9 IO PCB
Triumph of perseverance :)
Your video also helped motivate me to replace the headlamp in my car; I'd bought the replacement a few days ago, but I just now finally popped the hood and worked through all the physicality and fiddly-ness, and got it replaced, hurray!
Awesome! I'm definitely finding that working with real physical objects has a positive feedback effect. The more of this kind of stuff I do, the more I feel like doing.
Great video man, also good job on repairing that PCB. Its really common to search the reason its not working after a lot of time being the least important thing on it hehe. On other topic how hard is to get replacements and new mixes in your country?
Not too hard, but it does take some effort. For new mixes, I tried to buy from Andamiro directly, but couldn't really get anywhere by e-mailing them. I was directed by a community member to Phil Arrington, who acts as a distributor in the US. I bought my Prime 2 and Infinity upgrades through him, and he was great. For replacement parts, I usually order through betsonparts.com, which is reasonably easy.
I see, i was asking because i think there's just one business acting as distributor for Prime 2; also about spare parts sensors are the easiest ones, anything else seems a little hard to get. Any other non-up to date mixes are "easier" to get from 3rd Parties in some facebook groups. Im trying to get my hands on an old Mk3 with Extra but seems its really hard =/
So, that PCB on Player 2 is the so called PIU I/O?
Nope, I'm pretty sure the PIUIO is the board that sits inside the computer (on the PCI bus, I think?) and has the JAMMA interface on it. I think the official name for this one is "foot PCB"...at least, that's what ArcadeSpareParts calls it.
This one? static.arcadespareparts.com/images/screenshots/large/35035.jpg
So, that exchenge of the IC componente didn't solved the P2 problem? OH! Resistor and a jumper. Always less than what we think. That's good.
Do you have a list of the troubleshooting procedures you went through? Both my pads do not have lights working
Off the top of my head:
- Is it running official software? Some unofficial setups don't communicate with the pad lights.
- Are the red, white, and blue (from right to left) cables plugged into the correct connectors on the PIUIO next to the JAMMA interface? Photo here: photos.google.com/share/AF1QipMictblt5UWj21MLR7pv8dg-5JUH8qXNqTHAiJ5ogSoEDwAaCgOjZ-uaEeLAAuK4A?key=Nzc2ZTczVmJSMTl2Mm9xM1FTQmNydWFwNmdfZ2tB
- Does anything light up when you use the light test in the operator menu?
If no lights work on either pad, it makes me think it's probably something upstream from the foot PCB. Do the cabinet lights work?
Awesome! Where did you got that PIU? I'm really curious, I'm thinking about buying one.
eBay. Everyone I've talked to has recommended watching local arcades to see if they're changing stock or closing and buying machines when that happened, but I didn't really have anything around me. There's also a Facebook group for buying/selling/trading used dance machines that might be worth a look if Facebook is your kind of thing.
Thanks!
Nice job fixing it. i have to admit it was a bit painful for me to watch, but as it is not your gig, it was ok. Props. Surprised it was an array, they do fail but not often, they can be tough to find on these boards. I've had to fix many a damaged board. ua-cam.com/video/gRgWCtqsquc/v-deo.htmlsi=zCFp_DNf4wOpUB4c. thanks
I got some questions. Can you help me?
