I love the era when the scoring went from 500 points for a big single score to 5 MILLION! Cool vid!
Cool pinball machine! I was in Las Vegas, in Pinball of Fame, in 2017 and I love that place!
I'd say the diode had reverse leakage. Easiest way of testing it would be to have your multi-meter set on ohms, then reverse connect your meter probes (this is known as a punch-through test). If you get a reading, then it's possible it's leaky. But to be certain, you need to lift one leg of the diode out of circuit and test it again. Same can be done on transistors, though darlingtons and tranys that have either an internal diode or internal resistors, the test won't work... An excellent diagnosis and fix on the diode and gearbox Ron... WELL DONE!!! 10/10
Thank you Dero I couldn't find anything wrong with it but I wasn't on ohms so maybe that would have caught some difference.. thanks for watching!
You are so great Ron! A missing diodes on the switches, then a simple bad diode of the bulb socket, those were the problem and you found them and fix them! and the motor issue too. I enjoyed the video. Best Regards from Argentina!
Thank you Pablo, that's very kind of you to say. I really enjoy making these videos knowing that people like you get some entertainment and enjoyment out of them. We'll see you on the next one, thank you for watching My Friend in Argentina!!!
One diode on a random light - wow. I guess we don’t appreciate how much time it took to work through the other options and eliminate them but you got there - somewhere you probably could never have expected to end up. Good processes and thinking eventually get you to the right place. That was pretty fun to watch.
Thanks David, glad you enjoyed it!
AWESOME FIX RONNIE!!!!! Who would have known the lightbulb and socket was the problem?!?!?!? YOU DA MAN!!!!! Keep the great videos coming. Always looking forward to the next one.
Nice catch old chap ! bloody diode taking a leak on your day, and it's a good job ya had ya lube on ya.....cheers.
Thank you Andymouse123 we always enjoy having you by :)
Diodes can test fine but break down in reverse voltage if the voltage is higher than a certain amount depends on the fault the voltage amount
Yes I run into them from time to time that you can't test without a load... but oh well we figured it out!
Nice work Ron, long processes to find out it's a diode on a light. It's funny how one little part can screw up a lot of other parts not related.
Awesome as usual! You profess to not know electronics, but I think you’re sandbagging! 😀
Don’t sell yourself short. You know a HECK of a lot of more electronics than you let on. In fact, you would put some “certified technicians” that I’ve worked with to shame.
An old man told me one time, A good education will teach you how to spell "Experience" :) Thanks for watching Slide100!
You'll be that old man one day!
Great job, on getting that motor running. Is that a lower playfield with a car in it? Maybe that is in the next video. Thanks Ronnie
Yup, you bash the car with the flipper! It's pretty cool, you'll see it in a later video :)
Yep..it combines with a video thing to simulate the car-crushing minigame from the SF2 arcade game.
So the diode could have been shorting under voltage. I guess it is there to keep the bulb from coming on falsely if a pulse goes the other way.
On the motor, a lot of shaded pole motors do have solder there to mount the "shadings." And I've oiled between the rotor and stator before, but only with the motor disassembled, and applied by finger. Really, with that sort of thing, I'd use a Teflon spray to where it is slick but not oily. I've done that before with lawnmower magnetos and flywheels. And I'd try to adjust those where they were as close as possible but not touching.
I think that flipper more of a Guile kick than a Chun-Li.
But just being nitpicky.
I can see that, somebody really just wanted to put that Chun-Li plastic like that on there though... it works pretty good in gameplay when you 'fight' Chun Li!
Piezo! Senses motion/strain. Cool.
Don’t spin the motors when connected you can make voltages that will damage circuits (back emf)
Whew, that was a close call! I spun the motor while connected and did not make back emf that will damage circuits, barely got out by the skin of my teeth!
@@LyonsArcade just trying to be helpful you can spin them a hundred time and nothing then next time you damage something. but never mind. why watch videos if you cant comment bye
@@brianwild4640 I have a "toy" DJ turntable that tries hard to appear like a SL1200 but is belt driven, flimsy plastic all over, and flexy to the point I can easily push the platter to rub against the plinth. When it is turned off, if I spin the platter fast enough, the power light and built in amp board come to life. Yeah, toying too much with it could damage the preamp or motor control.
It is fine as a HiFi turntable though and allows fitting a cartridge of my choice, and its worst problem was the built-in transformer that produced an audible hum whenever the stylus was on the record, even when the platter motor was off, so I ripped it out and wired in a wall wart from an old DSL modem. No more hum.
@@brianwild4640 Don't you mind Ronnie, he's jes playin'. You try and find a TH-cam channel where they even respond to your comment. ;-) Have a good one!
@@djmips np there are plenty
Nice! Such a hated game by some, but I still need one in my collection!
People hate anything that's different, thanks for watching Chaz!
@@LyonsArcade agreed!!!! Keep up the vids man!
Great work as usual😎👍
Thank you Danijel, we appreciate you watching!
@@LyonsArcade No problem😎👍That was a hard to find and repair😬
Something I noticed when you were play testing at the end: the sound definitely has an issue, specifically the music. It's supposed to play a full tune once the ball is in play but it's only doing the drum beat for the intro throughout the game. I also didn't hear any sound effects, either, which might all be tied to the same issue. My uneducated guess would be maybe a bad chip on the sound board? Don't mind me, I'm just trying to see how accurate my troubleshooting skills are :P
They're pretty good.... I thought something sounded off, and I kept messing with it and eventually decided there must be something wrong, I eventually figured out the Yamaha sound chip on the sound board was dead! All it was playing was the voice calls, and some of the percussion, all of the tunes out of the YM2151 were missing. So you're hearing what it sounds like without a YM2151 :) Good ear!
It's crazy how such a small part could give a big trouble like that!
Ok, I admit to laughing at the diode thing.
Thanks Sam we appreciate it!!!!
So the fix cost 3 cents, plus 8 hours of tech time to identify and replace the broken diode! Yah gotta love electronics.
Reminds me of the old joke about why the tech charged $100 to replace a 10-cent piece...10 cents for the part, $99.90 for both the time spent finding the part to replace, *and* the know-how to know *which* part to replace...
That's pretty much how it works! Thanks for watching Fred!
Cool
To bad you don't have an octopus tester. Very simple device but you do need an oscilloscope to use it. When testing semiconductors it will show failures you'll never see with a simple DMM. With it I could go through that entire diode board in about 30 seconds.
It could be kind. If you don't score enough points on a ball it gives you another chance.
Yodel ay hee hoo
Cool video! How are you doing?
I'm doing great Petri547, I hope you are!
Yep I am. If there's not much raining tomorrow at Vantaa. I'm gonna have mushroom hunting at my day off. 😀💪
Seems like with the bad diode the socket was sending voltage into the switch matrix which freaked out the logic.
It is backfeeding voltage because they don't have a diode
Is the diode on the wrong way around ?
You would think so but no I put the new one the exact way and confirmed with the schematics, it was correct just 'leaky' I suppose. Thanks for watching Keith!
@@LyonsArcade just goes to show I must not assume the pin ball maker would use the center pin of the bulb as the positive , also why would they include an EMF protection diode for the small coil of a light bulb but obviously it is needed - than you for your kind reply.
I don't understand how the switch and Lamp matrices affected each other?
They're combined, they used the same strobes for both, so if one lamp messes up or has a bad diode it can mess up the switches on that same strobe. With the diode messed up voltage goes places it shouldn't go and the chips on the MPU and driver board can't read the matrix properly. Thanks for watching Thomas!
@@LyonsArcade I guess that was a Gottlieb thing?
Can you give me advice on collecting old consoles and games like the NES and Megadrive, I'm in Ireland so I find it hard to get alot of retro games
@@exidy-yt ok thanks
I can, only, see them using the diode in series to block voltage back-feeding. There is zero reason to put a diode in parallel with a bulb...
The bulbs are in a matrix so they need it to turn on only that bulb.
This is a dangerous channel. I have no particular interest in owning a pinball machine, but somebody in town is selling a working (with issues) Williams EM machine and I kind of want to tinker after watching many of your videos. Please, will somebody talk me down?
Nah...if it's a game you like to play, you have the room for the sucker, and most importantly can *afford* it, go for it.
There is no substitute for experience
If anyone other than Sully was flying that flight, it would have ended horrifying
He knew the plane and knew to turn on the APU immediately, even though it wasn't on the emergency checklist
JOES CLASSIC, If you have used the Logic Probe you could of put the logic probe on each side of the BAD diode to measure the Strobe signal. A GOOD Diode would measure the Strobe signal on both sides of the diode using a logic probe. A BAD Diode would measure the Strobe signal on both sides of the diode using a logic probe. When you close the switch it will apply Ground to the diode and column which the strobe signal I'm guessing should be grounded so no strobe signal because the diode has sinked the strobe signal to ground? A BAD diode will "not ground" the strobe signal, so when the switch is closed it will connect the strobe signal ROW to the column ground which will ground the strobe signal to the column ground. Maybe someone can correct me because I don't know the theory beside what the diode is doing and how the strobe signal ROW gets grounded by the Column but it shouldn't matter if the diode is GOOD or BAD it seems logically it would ground the Strobe signal Row either if the diode is shorted or GOOD so it doesn't make sense to me.
Wow we haven't heard the twilight zone music in a while. You've had a good long streak!
hahaha well it's back, lol Thanks for watching Ray!
HELLO, DO YOU KNOW THE NAME OF THE FILE (.DAT) OF THE GPROM (U2) THANKS.
