Hi Y'all, my friend has a Ms Pac cabaret on location in her cafe. The customers love the heck out of it and it is sort of the star attraction there, It has been running 5-6 days a week pretty solid for the last seven years, but has started to act up. The screen is pink, there is some logic issue occasionally with going left, and occasionally it reboots.

I have purchased a quick replacement PCB for her, but I would like to have the OG one fixed and bulletproofed a bit so they will always have a somewhat reliable back up. Who is the go to for repairs who doesn't take eight months for a turnaround?
 
You're sure it's a PCB issue? Pac/Ms. Pac PCBs are so inexpensive, it's almost difficult to see how it's economical to pay to have one sent out for repair (including shipping both ways) versus just buying another one.

It's definitely a PCB issue, and while the cost of a working PCB is cheap, my time to drive there and back every time something comes up with it is not. So my hope was to get the OG bullet proofed as a backup.

This is an on site game that runs 8 hours a day and brings the customers a lot of joy so it will be worth it to them.

what is it doing? or not doing?
 
Have madrits do the 4 in 1 mod to it while he's at it. Love his mod and the way he installs it plus he'll only charge like 50$ extra or less, he also created the hardware that makes the mod possible on his own. Gives you pac and ms pac fast and slow, freeplay with attract and a nicer menu than highscore saves overbloated menu. Also while you're in there if the fuses and fuse blocks are original may as well replace them for your friend.

Thanks. I am pretty sure I replaced the fuse blocks before I put it on site for them, but will definitely be checking the when I go back down to install the new PCB and grab the old one.

The screen is pink, there is some logic issue occasionally with it where it will stop going left, and occasionally it reboots. I'll dig through my phone later for the pics that they sent. This is not consistent. Very intermittent.

You got bad sockets definitely, possibly some bad ttl chips or rams. If it's rebooting it's watchdogging, makes me think there's a cpu or clock issue. Could also be the daughter cards. Definitely a job for Mr Slava Madrits, pacman pcbs are really tough to work on and he's especially skilled and well versed. The traces are prone to lifting, pacman pcbs are like the gm and ford of the arcade world, absolutely terribly made when compared to the quality of something like a nintendo pcb which is like the toyota of the arcade world, extremely dependable and well built. I'm sure you've seen my negative posts about multi-game kits and high score save kits, it's my opinion from my own experience that 99% of those devices have no business being sold to the general public because they do damage sockets over time. When you damage the sockets you've effetively killed the pcb unless the owner has the money to send out their pcb to someone experienced to fix it or has the skills to do it themselves. Slava's multi-pac when he installs it will not weigh down sockets and damage stuff it's really well designed when compared to something like high score saves multipac or multi-kong. It's the only multigame in good conscious I can recommend and I recommend you have Slava do it himself.
 
LOL!
Pacman has to be the best documented and easiest board to work on.

Anyone who can't replace a socket has no business in this hobby.
I meant for people who aren't experienced, they are harder to work on than other pcbs for the fact their traces lift super easily. Not a good beginner board in my opinion.

You do realize 90% of the members of this forum do not do their own pcb work? So 90% of the people on this site shouldn't be allowed?

Also hudson why are you giving me shit? I actually respect you as a repairman and I like when you give douchebags like andrewb shit because he deserves it being an asshole to people for no reason. I'm genuinely trying to offer advice to the best of my ability, you're now acting like Andrewb for no reason. Please refrain from being negative like that, if you have something constructive to say, say it but all you did is alienate people with your statement and sound like a pompous asshole like Andrewb

I would check the edge connector and card edge. Bad connections there can cause most if not all of these problems.
On every board I ever look at, one of the first things I normally do is clean / polish card edge and then put two drops of DeOxit between my fingers and wipe across both sides.

I did that the last time I was out there over the summer. As @Mattspad stated this more than likely has some bad chips and sockets.

I took a look at Mike's page and saw a few things that resembled what they are experiencing, but I do not have the time to work on this for them. I barely have time to fix my own stuff.

I was being positive, clown.
Pacman is so damn simple that anyone should be able to fix it.

...what's negative is pretending it's super complex and there's only 1-2 people who could possibly fix it, and there's no way they could figure it out themselves...

Which is still a good thing to experience. Someone who wants to repair their own boards should know how to fix their screwups (both troubleshooting and bodge work). It is incredibly valuable to learn how to do this kind of work. It also keeps ya humble. I work on boards just about every other day now and still occasionally make a mistake.

Ultimately, the secret is use the right tools, don't have your iron/desolder gun set too high, and don't force anything. The last part is the most important, if you are going unga boonga on the board you are gonna cause damage.



To actually chime in, check the power on the game board. Make sure you are getting a solid 5V on the chips and don't have too much ripple. Pacman boards have the power supply built on the board and they sometimes go south. Also make sure your harness connection is solid. I'd start there.

There's a reason why I attach a Mr before Slava's name, he's a class act and he deserves respect. There's a reason why you'll never have that here for all the good work you do, it's practically a meme whenever someone says something about pcbs you chime in to call them a dumbass and say you've already done that.

You cannot assume people all have the same skill level, do you read peoples posts on this forum actually before you start thinking of bullshit to say? If you did you'd notice 90% of people on this forum do not repair their own pcbs, acknowledging your limitations as a person is also perfectly acceptable, if it saves a pcb then knowing your limitations is a very important thing. Anyways out of respect for OP you should post something that could actually help her instead of coming after me since you know so much about pacman apparently

I agree but read what I said above. It's not easy to teach people who are set in their ways or don't understand the value of using the right tool. At least you are trying to help OP

I'm in the Pinball Repair group on Facebook. as probably everyone should know, pinball is a rich man's game, and at the beginning of the year when I had one of those Rottendog MPU327-04's crap out in Firepower at work I got to thinking about this. one of those costs $500 new, and in the event it breaks nobody on the planet really knows how to fix them or wants to fix them. despite their asking price, I came to the realization that they really are disposable junk. anytime someone posts in Pinball Repair with a mere hint of something wrong with an MPU or driver board, of the 40 some odd comments (a quantity above 5 is grounds for me to not even touch it) I would say half of them are along the lines of "buy a Rottendog combo board!" and every time I read that, to me, it's cringe, because I know how to fix those MPUs and driver boards on the early solid state games... but the people making the posts don't. the question I had about those Rottendog replacements was answered back in January: there's just a collective of people that have money and want to be able to play their games. they could probably save money paying someone like a Chris Hibler to fix their original boards, but it's just easier and more time effective to get the Rottendog board. I wound up reverting that Firepower back to original hardware, the first time I ever did a restoration-esque deep dive on one of those, and I did 3 more games at work over the next several months. for me it was gratifying because it was a new thing I hadn't yet done, and I've done many over the last 18 years.

but back to the point about people's unwillingness to just learn how to fix games, like I said, they just have money and want to play their games. they want to socialize with people and drink beer or whatever it is that they would rather do instead. I don't judge those people for it, I remember a point in my life where I wish I could just play games without all the gravity of everything needing to be perfect. every arcade I've worked at full time I committed myself to making 100% of the games work as much as I was capable of doing. because in this current age of the last 15 years or so where people go places and have what they consider a negative experience, the one thing they won't be able to do then is critique a bunch of broken games (like so many other arcade Google/Yelp pages do) because then that would reflect poorly on me. to date I've only sent a Spy Hunter to cdjump to fix a few years ago because I came to another realization that I'm not in my 20s anymore and my time not being allocated to a thing I don't have intimate understanding of how it works is the more valuable thing at a minor hit in what he charges.

unlike a lot of the specialist people here, I never had the luxury of just concentrating on a handful of hardware platforms. I'm a game technician, I don't discriminate; it was always expected of me to just magically be able to fix anything and everything. on one hand it was a dream that 4 year old me had of wanting to learn how to do it; on the other in the real world it's at times an element where I wish I could put the toothpaste back in the tube.

I support @nerdygrrl with whichever next step she takes, because she's a model citizen outside of this stupid arcade world we exist in. stay gold, Mark.
