Ordered. Thanks

You will still have to manually clear those junk inputs I’m pretty sure. Which is done by going into the test menu and triggering the coin chute to clear the junk scores.

I’m so annoying, I got a new MPU, got the game working 100% played it for a few days and then the same issue happened again. RCV 40 is out, right saucer, right spinner and right inlane don’t register. This is ridiculous. It is intermittent but after a few days it becomes permanent...

Do you think a bad diode on one of them is screwing up the MPU??? https://pinside.com/pinball/forum/topic/save-my-baby-bpm-is-a-diode-is-issue

Have you tried to just pull all the connectors and reseat them on the board? I would try that and see what happens. I have had my left side not respond and reseating the connectors fixes it for awhile. I actually purchased a complete connector and pin kit and have yet to do it, I hate re-pinning.

After a bit my video goes out. (also does not play blind) I turn it off to let it cool down, turn it back on and it's OK.
Intervals happening more frequently lately. I believe TMS chip is going out.

I have a new TMS, but I want to add a fan to it first. Anyone else do this?
I remember some instructions out there somewhere...

Yes, I’ve reseated it a few times... I think there’s a bad diode somewhere on one of the switches that eventually takes out the whole row. It’s just so weird it works at first for a couple days...

#708 3 months ago

Yes! thanks! That's where I saw the instructions earlier.
Wiring looks to be using 12 unregulated between (TP4) and ground (TP3)
How is that fan attached to the chip?

Also, anybody simply use one of these to help cool the TMS9928?

Tonight I went to play Baby Pac and I turned it on, started a game and it just sits there. It wont go any further. Any ideas where I should look? Im assuming its on the Vidiot board? I did smell something electrical burn very faintly.

I understand why people hate this game. Finally repinned J1 and my switch issues went away!
... except now completely at random half of my solenoids don’t respond.
I put it in solenoid test and took a video of it. Seriously.
Sometimes 2-4 cycles would work flawlessly, and then suddenly the drop target bank stops working, then the kick out hole stops working, then none of the memory targets.
THEN THE NEXT CYCLE THEY ALL WORK AGAIN.
How does this keep happening?!? Why do these issues seem totally and completely bizarre??

Cracked solder joints? Worn out header pins? Bad crimps?

Crimps are good, just went and repinned the whole think and tugged on them to make sure they’re solid. Header pins have been replaced. And from my inspections I haven’t seen any cracked or cold solder joints. It’s very frustrating to track down. Game is working fine again and did so for about an hour.
This thing drives me nuts.

I am looking to buy a Baby Pac Man in nice condition but the screen is acting up. When turned on it is red like in the picture. After a while the red disappears suddenly and the screen looks normal. Any suggestions on what that could be? I am guessing caps but I really have no idea. Hope someone here knows.

Its likely bad color pots on the vidiot pcb. At least the red pot, but Id change them all as the stock ones are low quality.

Thanks I Will look into that when I get the here.

Send me your Vidiot boards for repair or rebuild. Tech work and good price.

Hi Everyone, I've restored a few games through the years but haven't had the time or funds to work on one project in particular. It's mostly due to settling down and having way too many kids so all the fun projects were shelved for years. I now finally have the ability to get back to some of these projects and my favorite to finish is a Baby Pac Man restoration. I have everything I need to get this moving but a tube and chassis. Seems my old connections are either no longer in business or just do not have access to tubes any more. Can anyone make a recommendation where I could look to find a tube and chassis for a Wells Gardner k4800. I have come up with nothing since starting my search in the beginning of this year so I appreciate any tips, pointers, recommendations that anyone can point me in and thanks for any help!! I am so close to finishing this and putting it next to my Ms Pac. Man for hours of enjoyment!!

If you don't have a 4800, I would look for a k7000 instead. They are easier to find and a direct replacement.

Most people probably aren't going to want to ship tubes and it would be expensive. I'd look around locally for operators/multicade people who pull CRT's to "upgrade" games to LCD monitors.

That is great to hear. I'll start looking for a k7000. I couldn't find much online about anyone using anything else other than an LCD and I really want to put a tube back in this game. Thanks again!

Hello all! I’m back to work on a new to me baby Pac! I’m having issues with a few playfield lights. I have replaced all of my transistors on the lamp board with the 106-6g as recommended. I still have a few issues left. I have also repinned all of my connectors. And checked the socket diodes on the remaining issues. Both the transistors and the diodes check out well on all remaining that do not light. However they all share the u1 chip in common I suspect that as the issue after all of this testing and replacing. If anyone has a playfield lightboard or know where I could get one I would love it to replace all of these stupid bayonet 555 sockets? Or any links to buy new 555 bayonet sockets? Thanks in advance!

#726 55 days ago

Update replacing u2 on the lamp board fixed everything! She’s up and running 100 percent! Still would like to replace the lamps with the playfield board....

I'm working on a vidiot that is playing the wrong sounds. Vidiot fully boots and plays video in game with pinball. The sound tests function, communication tests pass. The sound cpu and sound rom are known working from another board. Sound rom socket has been replaced, cpu socket is original but has continuity on all pins. Also socketed/replaced u28 and u31 thinking it was an adressing issue but no change in symptoms. Any suggestions? Can the dac cause this issue?

#728 28 days ago

Have the connectors been repinned? Maybe a couple of wires got swapped around by mistake?

Sorry, I should have mentioned that I am testing the vidiot in a fully working game that has had all of the connectors replaced. All the headers on project vidiot are also replaced.

Solder bridge or shorted trace on the PCB? Malfunctioning CPU chip?

#731 27 days ago

After getting tunnel vision focusing on the output of the sound cpu and buzzing out all the traces, I started looking at the inputs to the sound cpu. Cpu to dac traces were good, but cpu to pia were not. One trace didn't have continuity and after folllwing it through many vias, the problem was obvious. At somepoint in this board's life, a tech who I will guess was aptly named Corey Crowbar, needed to remove the pia at U7 and decided to use the pcb as a fulcrum. In doing so, two traces were damaged. Jumper wires in place and the sound is back to fully working!

Does anyone know what chip on the vidiot board may be causing this? I thought it might be the sync So I replaced all of the pots at once and have the same results. This happens at random however. Sometimes it boots up and the screen is perfectly fine and plays great, and other times it looks like the crap in picture here. Thanks in advance for any help. Sorry the pics are sideways I can’t swing them around on my mobile app☹️

Adjust the horizontal hold/sync on the monitor. There is also the sync pot on the vidiot, and you might have to find the balance between the two pots.

Fixed it it was the horizontal frequency on the monitor itself
