Follow along as we do some troubleshooting and repair work on a Bally Mystic pinball machine.
Can you tell what is the reference for the NVRAM ?
Hi. You saved me ! I bought the grand lizard 2 month ago and the background music never worked. It was the connector installed backward ! Thank you very much for this really helpful video !
Excellent troubleshooting video. Very clear, to the point, and easy to follow. Thank you!
Great work! Helped me a ton. Video is still helping people out. Wish there were more like it.
My ultimate Arcade battery replacement how to reboot 😢
When I turn mine on now it says power save mode would that be the battery I bought it 6 years ago I really love the game 265 games on it I never had problems till now what can I do...
Hey you still active? I got an zaccaria G1 Machine and would need some expertise.
This particular pinball should be burned and trashed
waiting for part 3 here...🙏🏻
I am having keyboard issues and I can't get out of my arcade menu. Any suggestions?
Hi after i replaced the cmos battery the arcade monitor is black but the computer goes on and the fan any help would be appreciated Thx
I have this machine. At the top by the solenoid relay I see a red button. Is this a momentary button or switch? Mine appears to be broken. Also dumb question, what is this switch for?
Man I just stumbled across this channel. What a great video. COME BACK.....
Love game girl
Great video. Will be helpful, I wish. Just bought a Grand Lizard today with issues on switch 22 and switch 44 (this message appears on the board). Also, all the flippers died after our 4th game . any idea? thanks anyway!
Did you ever sell the UltraCade hardware if not contact me The.Retro.Cade.LVN@gmail.com love to add to our arcade
deseo comprar un pinball.precio?
THANK YOU
I have Mystic pinball. I can't get the lamps that don't flash on the back box to work. I also see you don't have lamps in the sockets either. Can you do another video showing how to fix this problem thanks.
Are you making more videos soon?
Was there other PIA part numbers besides the 6821 PIA that pinball games used? I forgot which pinball game in the 70's ballys, williams, gotliebb but there was a laundry list of dipswitch settings that was on the backdoor of the backbox which you had to save each dipswitch setting to EPROM or RAM one at a time which took hours to do. Any reasons why they did this? I think it was for the william systems 3,4 or a gotliebb MPU board. Most IRQ signals are generated from what in arcade games because ROM chips don't output IRQ signals any reasons why ROM chips don't output IRQ signals? Most ROM chips have a ROM signature value but how to you calculate the ROM signature value using a handheld calculator?
The williams system 1,2,3 and ballys system 1,2,3 motherboards had dipswitches you had to save for each configuration one at a time, any reasons why you have to save each setting one by one? Why does the driver boards use a PIA chip and not go direct to the CPU and not use a PIA chip?
Thanks for the comment. The first Williams solid state systems were System 3, 4, 6, 6a (Firepower), and 7. The classic Bally systems were -17 and -35. The DIP switch adjustments and the internal adjustments (stored in RAM) configure different things but you would have to ask the developers why they chose to make some things configured by DIP and some by software adjustments. My guess would be that the DIP switches are more for things that would be common to all games and the software adjustments are more of a per game adjustment, but I've never really though about it. As far as the PIAs are concerned, they're required to multiplex the outputs of the CPU. I would recommend reading through the 6821 PIA data sheet to get a better understanding of how it works and why it might have a place in a pinball machine.
New sub! Check out my comedy pinball repair videos =) May all your jackpots be super! =) I have a NOICE Blackjack, got 957 with intentional tilt, accidentally rolled it once...
I got a nice one. Woops, I'm not logged in as Gilbert Gottlieb. Hold on, I'll get you a new sub... Nice bro! =)
Thanks for the support, Heath!
Despised Linear flippers first time I saw them in '81 [45;00] I made my own expander board just used a 6V relay much simpler, if your worried about the incandescent light burning out you can put a 200 ohm resistor across it's socket contacts.[1:00] I would've swapped U10 first [1:06] don't short switch wires together that's why there are isolation diodes Hand held oscilloscope good tool for checking strobes and power supply ripple
Thanks for the comments. Good suggestion about using the 6V relay for the expander board. You won't break anything shorting the strobes to returns the way I demonstrated in the video. Electrically it's no different than closing all of the switches in that row/column at the same time. You've also got diodes in series with the PIA outputs driving the switch strobes and current limiting resistors on both the strobes and returns on the MPU. This method also has the benefit of checking the strobe and return sides of the circuit at the same time. Your strobes may look all good with an oscilloscope but you could still have a problem with the return side of the circuit on the MPU. I agree that an oscilloscope would be a great method to check the strobes, but not strictly necessary to fix these kinds of issues, in my opinion. I could have swapped U10 and U11 first to see if the problem changed, installed a new U10, or better yet checked the outputs of the PIA with a logic probe or oscilloscope. None of those would have solved the issue in this case, but logically it is a good suggestion. I don't like pulling chips if I don't have to. If I would have seen issues with the test I did then I would have moved on to troubleshooting issues with the MPU, like a bad U10. Thanks again for the feedback, it's much appreciated.
@@WarpZoneArcade Good video thanks for taking the time.
on my mystic display is not working
We have a problem with left flipper failure on a Williams Earthshaker machine. We are following your video and learning much, but we are not very experienced with electronics to this much detail. Machine diagnostics tell us a problem with switch 58. With this information, can we infer that it is not a problem with the flipper solenoid? At a loss as to our next move....... we're in NE Pa. Any comments or help would be appreciated.
I had a hard time watching the intro. reminded me of nazi book burning.
Good concept but man wath a bad intro was there....
Work just fine for me
I have a ultimate arcade needs a new battery how to reboot battery has been replaced
HELP ME PLEASE
Havent you posted this video before? im sure i commented on this video...
Yes you did, and thanks for the comment. I did another edit and re-uploaded. This will be the final version.
Finally a video using schematics with detailed explanation Would like to see more like this Well done
You prolly dont care at all but does someone know of a trick to get back into an Instagram account..? I somehow forgot my password. I love any tricks you can give me.
@Kole Fabian Instablaster ;)
@Judah Alberto I really appreciate your reply. I found the site on google and Im trying it out now. Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.
Can I please get some help with getting video to show up . I had a check sum error and a friend replaced the battery on the motherboard and he changed some settings but I think more settings need changed to show the video. Thanks so much
Could I pick your brain about an issue I'm having with the same Ultracade-Sumicom system? Email: duanetompkins@hotmail.com
did you move to a different account ? or are these 4 videos all you ever made ?
great video, thank you
during that speed test, do you think a dmd would "lag" if that circuit was messed up? I'm working on data east rocky and bullwinkle that lags, can't figure it out! This was a great video! Thank you =)
Excellent troubleshooting skills
Thanks. Very helpful.
Someone mentioned that the sounds are wrong. They're not "wrong" but most Elektras are adjusted to a different setting, which makes better sounds. Page 7 of the Elektra manual shows the sound options. Setting self test position 18 to "03" will make most scoring have a "noise effect with background". This is the setting most people are familiar with. The machine in the video has the setting at "00" or "01". If you're running a stock MPU board with no battery or a dead battery, the sounds will revert to 00 when the machine is restarted. Use a battery or NVRAM, or an Alltek replacement board, to keep the sound settings at 03.
Thanks for the great comment!
Seems like you have a problem with sound also. Sounds are not right
great vid. As an Elektra owner, I appreciated it. Rock on!
can you please email me at amer0636@aol.com i would like to buy it from you.
Where do you get those Switch testing boards? seems handy to have.
Thanks for the comment. You can get the switch boards from my friend Wayne at Pinitech. www.pinitech.com/
make more videos i love them
@19:20 CONVENTIONAL current flows the other way around, or it would just choose to go through the diodes instead of the coils (path of least resistance as you say).
Thanks for the comment. I wasn't really thinking about conventional vs. electron flow notation when I was doing the explanation. I'll keep that in mind for future videos.
Im glad you said that, was getting confused lol
Man- I just learned so much from that video! Thank you for explaining your logic and procedure, you helped me a TON!
Can somebody help me with a problem on a silverball mania 1981 Bally pinball. The machine starts led flashing 7 times startup sound and then it makes a bluuuuuuhghg sound and stops. I found out that both flippers are not working in the test program also I checked the fuses they are all one. I have seen in your video that the power must be around 43v I have only 18v I learned some tips from the video and will look further Roger Amsterdam Netherlands
Thank you for the explantation.
