@2:40 thanks for showing the pad; that's a gift that keeps on giving.
The pad makes it's triumphant return!
instablaster...
ULN 2003A is Trans Darlington NPN 50V 0.5A 16-Pin PDIP
Thank you Marissa, most of that though I still don't get, lol I looked up the datasheet and kind of got an idea of the voltages and things involved... This ends up being a two part video, but we've already filmed it and got to the conclusion so you'll see the rest of it Wednesday! Thank you for watching.
@@LyonsArcade "Darlington" just means "stacked transistors" in a basic sense. Transistor into another transistor.
Ron the Darlington in simplest terms is a transistor. The chip is called Darlington array .....fancy way of saying heap( of 8) in a box.
This can be used to allow 5 v signals from computer bits , to talk to the ( say) 28V motors or solenoids. I
Ron, always fun to watch real electronics troubleshooting, not swaptronics.... thanks for taking us along.
Thanks for watching man I wish me the people just tried to fix stuff you can often figure it out!
uln2003 its a transistor array (darlington pair) so it can switch leds, relay coils etc from logic level input, they blow easy if you got a bad relay or coil etc.
This one must have been shorted for sure.
The ckt board with the coils and caps may be a crossover ckt for the speakers low, mid, hi freq range
My thought exactly!👍🏻
That's probably correct!
Man I love your sense of humor about the hatch back. Leave my plastic alone.. Made me laugh
Thanks Bryan, we appreciate you watching as always....
pin 8 of the ULN2003 is indeed ground, but they probably isolate ground on different pins of the power connector to prevent noise from the motors and such getting in and crashing the CPU. The stuff you saw on pin 8 is called a thermal relief; it makes it easier to solder the pin, so that the copper ground plane in the board won't suck the heat out and cause a cold joint. The 80C31 is an 8 bit microcontroller and is pretty common. The 74HC574 is an 8 bit latch, and seems to be connected to the ULN2003's, so when the 2003 smoked, it most likely did in the '574.
On Wednesday's video we'll be right back in that area trying to figure it out, thank you for the info Kevtris!
Thanks for raising awareness about the gas shocks, Ron! People usually ignore them and end up badly hurt when they fail. My dad got a broken nose years ago when it failed on the hatch of his Ford Escort :(
Suuuucks, man! My first car was a Mercury Lynx which I think was the same as the Escort...
One of my employees got nailed by an American Changer. It had the gas shock holding the top up, and I warned 'em that he would need to use the prop rod. He ignored the prop rod and jammed a coin box in the lid.
Once the changer figured he was leaning into it- The box shot out and the lid (probably 15lbs) clocked 'em right in the back of his noggin. He was actually treated for a minor concussion. (The company ensured he was taken care of 100%.)
I see those XBox 360s there. i need to come back and pick those up. You remember that OG XBOX I bought last time I was down there. I got that one fixed up and modded to be able to be able to play MAME arcade ROMS. It's pretty sweet. I also am in a KISS pinball owners group and I told a them about your channel and your KISS pinball repair videos this past weekend.
Very cool man, glad you got it going! We appreciate you spreading the good word as always :)
Enjoying your videos-I used to fix Rowe Ami, NSM and Wurlitzer but back in the old days of vinyl but mostly on site it was panel swapping although most faults were coin jams, record jams or wiring issues-never got to do component level so finding this interesting
Thanks for watching Kelvin glad you enjoyed it!
The philips 80C31 are standard microcontrollers, originally from intel (MCS-51 family). They don't have a rom and are just running whatever is burned into the EPROM next to it. The ULN series are mostly darlington transistor arrays for driving higher power stuff from low current logic. Fun video, thanks!
Thanks for watching!
8031 is some standard microcontroller. The ULN2003 is used on some pinball machines, maybe that's why you had some in stock.
Yeah I must have used it for something back in the day...
Had one of those. Rebuilt the amp and sounded amazing.
They're pretty awesome!
We had one of those at a godfathers pizza right next to a sunset riders game. We would put 1 song for hours and thought it was hilarious 😂
At one of the places I operated jukeboxes at there was this one dude who always wanted free credits, I'd give them to him and he'd play 20 minute long James Brown songs over and over again, lol. GET READY.... FOR DA BIG PAY BACK!!!
I build amusement machines from scratch and I think I'm gonna start implementing sharp arrow-shaped parts that could possibly cause death, you know, just to keep things interesting :)
Maybe some sort of medieval torture theme????
An IC is a combination of everything. Integrated Circuits are basically a complete circuit, but microscopic. They often contain multiple transistors, capacitors, resistors, inductors all on a microscopic level. In this case, the ULN2003A is a Darlington Transistor array, NPN about 50Volts, 1000hFE. So in this case, the chip is a few transistors in a chip, pretty high gain transistors too. I guess you could look at them similar to the transistors on a Bally Solenoid board, but a few of them all in one little chip.
That makes sense Brendan, either way it had a huge hole in it :) We'll pick up where we left off Wednesday!
@@LyonsArcade Yes, it was absolutely dead :) Probably died due to the motors running constantly, due to other errors :)
My father was the regional service Manager for Rowe Northeast.
He worked on some nice stuff :) Thanks for watching Digit654!
If my dad was alive, you would have called him and he’d help you fix it.
looking forward to hearing come back to life again guys !! Thank you for the video x ;)
Yep, transistors and chips make the same smell when toasted. ICs are just a complex combination of almost unfathomably small capacitors, resistors and transistors so their behavior can vary quite differently from one another especially in the early days. Some will just catch fire if they're powered while unloaded
Yep, better than it was, look forward to part 2...cheers.
See you Wednesday!
Hey man. Pretty sure those gas struts were never supposed to lift the lid only take the weight and make it a little easier. You can buy a special ROWE AMI plastic cover to lock the struts out, which is effectively what that pipes doing anyway. I’m sure it’s mentioned in TNT video.
When I used to operate them some of the rock olas would hold themselves up but we didn't operate many rowes at the company I worked at so I don't remember for sure...
Nice jukebox, but that old school floor model television grabbed my attention. I love those. What is it? Curtis Mathis? Zenith? ... Apologies for the off topic. 👍
It's a RCA XL-100
Some significant damage on that chip. Good reasoning.
Thanks again!
I have a CD100 and updated the player and came with new board sounds good, and before I replaced my player it was full of codes.
This one still has some sort of checksum error but it plays fine so not sure what that is....
Shaking this CD jukebox would have me thinking about the daggers on the door. A thought that would be on my mind before the door fell and impaled my head with a 2” spike.
It's pretty scary! Thanks for watching Se7enity!
the board with the coils looks to be a crossover network. uln2003a is an array of 7 NPN darlington transistors. NPN... Negative positive negative. made by Texas Instruments
We'll see if we can get it going on today's video....
80 C 51 = 80 C 31 but with internal ROM. Ordered factory programmed saves board area in hi volume boards...you have the 80C31. Simple micro processor.
We'll have to get up close and personal with that one in wednesdays video....
Wonderful magic smoke that's quite toxic.
Isn't most smoke toxic though ? :)
Thanks again 😉
Thanks for watching!
those doors make me think of back car doors so I have no doubt they're heavy
6:28 dude that board is a cross over it's for separate frequencies, i mean one connection goes to the woofers or subwoofers and the other for the mids and highs it's simple but funcional and actually the new speakers comes with one of this thingies inside
Looks heavy duty :)
@@LyonsArcade yeah but it's just the aparece maybe, the good stuff is in the inductors, if these are made with good high quality copper the quality of the x-over going to be superB or maybe it's just like that for the power of the amplifier, who i think is an AB class amp or mosfet class D, who knows
Only one part with a smoking hole in it ?
TV I'm fixing, has two ICs like that, as voltage regulators don't usually hold suicide pacts there is a 3rd charred part in the PSU.
Two shorted capacitors, one which which looks like it's been on fire.
So yeah, 9v into regulators that only take 5.5V max.
$80 to buy replacement PCBs, $1.40 for replacement chips, once I found some actually in stock.
At the moment even brand new parts that are still made can be hard to find.
I'd definitely rather fix them than buy a replacement, for sure!
People who make jukeboxes: Nah. That doesn't look like an arrow.
Me: I swear that arrow is pointing to my head thinking "We're gonna impale him huh buddies?"
XD
Looks dangerous to me :)
it plays cd's, has daggers and it has it's own smoke machine... Sjeesh! these jukeboxes come with more options every day..... But does it make coffee?.... (or tea) :D
It roasts chips too :D
It had some coffee or something spilled on the keyboard, does that count?
@@LyonsArcade sure! :D
ULN2003 is a hex Darlington driver, for relays? lamps
Thanks Pete!
that chip probably controls several lines, maybe you can tell which one burned out the chip- could also be one of those little darlington pairs just failed on its own
We'll have to look further into it on Wednesday's video!
now replace the rear window defroster on that hatch
We ended up trying to use that same crap that you fix the window defrosters with, on the dart board membranes.... I'm using more auto parts than arcade parts anymore :)
you have to take those "blank" CDs out that are rotating now on the display, and see what's on them.
I think they came from Rowe with those in it :)
@@LyonsArcade yeah they did... I am very curious what's on them, if anything. lol. radio shack used to sell CD desk clocks with similar blank CDs, and I was always curious what was on those. I suspect they are defective discs or overruns, so there could be anything on them
Its got life in.... It Will bee fine😎👍
Yup it's trying a little bit all we got to do is help it...
Ooooooo that smell!
Can-cha smell that smell!
Yes magic smoke comes in flavors!
Somebodies gotta call somebody haha nice one Joe;) Quite jealous you 3 brothers are soo close..me and my 2 brothers dont talk mostly because they did better than i did..whatever thats family for ya
yeah i remember these in bars in the late 80s oh that smell is concentrated cigarette smoke from every bar its been in
Yup, it's all the flavors mixed together :)
At least it been updated to a pro 12 player and new basket
Yup they had kept it up to date it seems like...
What's up with the Seeburg DS160 (or DS100) briefly visible at 19:40? Is that the one you were messing with awhile back getting the Tormat unit working? Was that one of those rare videos where you put up part one but didn't get it working and didn't put up the second video? I was hoping to see your results for when I finally get my DS100 down here from Pennsylvania and get into its selection mechanism. Though I'm sure that a lot of its issues are just old ass caps.
12:15 Sylvester, the disco queern or the cartoon cat?
Jukebox that can "stab your a$$". Frightening. lol
I see no other reason they designed it like that :)
Damokles' Jukebox.
Darlington transistor array ULN2003A
We'll see more about it in Wednesday's video!
I have rowe too with the problem with mech board. First there was a RAM fault. I changed 6116 which is RAM memory. After that RAM error went away and it gave 05-62, which is CDM communication error. Then I also replaced the microcircuits U2 and U3, which communicate between the mech board microprocessor and the CDM. Still the same problem, the board error light stays on after the second flash and the CDM COMM light stays on, flashing about every second. Jukebox not working. There are also no error messages anymore.
Then when I changed another MECHANISM CONTROL BOARD and I used the same CD Player cable, with that the jukebox works fine.
I also measured that the CDM receives +5V and +9V voltages.
Is the next processor to be replaced, U4(8031)?
Or where could it be wrong? I looked at the wiring diagram that the U2 and U3 circuits are the only ones between the processor and the CDM...
Or what stops the MECH BOARD after the second led flashes. The manual doesn't say anything about that.
The MECH BOARD should blink three times for it to turn on, right?
I tested with an intact MECH BOARD so that I put only the power connector on it, after which the board error flashes three times and after that the SCAN/TRANS light stays on. The broken board, on the other hand, flashes only twice and BOARD ERROR stays on after the second flash and CDM COMM stays on.
What is wrong with that board?
It goes down through the board veah the viah that's the rout it takes to the roots
joe´s classic good video
Thanks Luck Wilder!
I love the smell of burnt chips Smells like victory .....or at least an easily found fault....
Yup, nothing like the smoke test to find what burnt up :)
How do i locate the follow up video?

Hola que debo hacer hacer si en la rockola me aparec not always ht
It's the jailhouse jukebox that'll shank you in your sleep.
Yup, WATCH YOUR BACK
Off subject of this video but are those used Xbox 360’s I see on the floor to the right of the jukebox? In other words do you have some for sale
Yes those are all broken, we sell them for parts.
@@LyonsArcade ah cool I’ve been looking for a used one just so I can play tiger woods golf . Literally just for that game lol
Rowe: I QUIT! *blows fuse burns component
Basically yup, it threw a fit and went out the door, lol We gave it a little raise, let it take a little vacation and it's back to work now, haha Thank you for watching George I like your spirit buddy
“I’m YOUNG”… are you sure about that? I’m fairly young and I still wouldn’t want to be impaled by a jukebox door.
The mechanism control computer is blowing smoke...
takes unit out...
It's _literally called_ the Mechanism Control Computer.
O_o
The designer of these was not very imaginative I guess...
RE: Chips
ULN series chips are custom application-specific transistor arrays. Typical types are for matched transistor arrays and (high voltage) drivers eg. for driving a VFD or, in your case, providing a "high current" voltage sink like an open collector invertor but sinks more current than a normal invertor. Careful using sockets for it as there may be more current going through the socket than you normally expect, don't use a cheap socket.
The 80C31 is an NXP (re Phillips) part that is their version of an Intel 80C51 (8051) micro-controller. So that's likely the brains of the controller. 8051 uC's are really old controllers going back to the beginning of 1980 but is still in-use in new designs even today. I used one in a product I designed many years ago.
RE: AC Motors
Windings DC resistance will be low. These motors run of 50/60 cycle AC and so to really get an idea of the winding resistance (or impedance really) one would have to run a low voltage AC through it via a divider network and measure the AC voltage drop across it (and possibly the current going through it, depending on the test setup) and determine the impedance. Or just hit it with full power and see if it smokes. :D
Cheers,
Thanks Eddy, I’ll bet the reason I already had those 2003’s is because I needed them for a display now that you mention it. I’ve worked on some of the rock ola displays in the past....
Had felt the metal spike in the head a few times, not fun.
