Yes sir, its definitely worth fixing these boards not only does it keep your Stern Stock and Vintage but you are also teaching others and yourself how to fix those tricky PCB issues.

[@mikekell9889]

I appreciate the new camera. Noticed the buggered ground trace before you even zoomed in. Lol.

[@LyonsArcade]

[@Dark_eVader]

7 counts and the sweet chorus of Symphony No. 9 just made me smile and you have once again made my day complete! Thank you Ron!

[@LyonsArcade]

I'm glad somebody else is getting it :) To me it's cool seeing the thing come back to life, these machines were built with a purpose, it's very cool to see them realize their purpose again. It's never lost on me, that yes there are a few things not working but once you fix those hundreds of other little things do their thing to make it work. So for every bulb that's burnt out there's a bulb socket that still works if the bulb is good, LOL. Or the switches haven't been hit in 20 years but the ball rolls over it and the switch works. So it's easy to see the parts that don't work but MOST of the parts DO still work.

[@whiskyguzzler982]

Seriously, these videos are an inspiration and I have more admiration for your work than I can express. I have done some small repairs, but you dive without hesitation into things that look hopeless. You make me believe that all things are possible if one is willing to put in the hard work and has enough love of the game. Your commentary and sharing takes it to the next level. Much thanks for all you do.

[@LyonsArcade]

Thank you for your kind words, Gary!

[@DavidWilliams-rn6uq]

Hey Ron - one thing you might consider for really bad copper corrosion like this is copper foil tape. You can cut it to form new PCB traces for the big stuff like that ground plane. It can then be bonded electrically by soldering it to the remains of the original trace. It would be a bit fiddly for the thin traces, of course. Good work getting it fixed! I have some things I need to go back and pry apart myself to see if they might be victims of corrosion...

[@LyonsArcade]

We just got in a Wiliams Pennant Fever and I just KNEW that damn thing was going to be rotted away with battery damage... we opened it up... and it's still in perfect shape, I couldn't believe it. It seems some of the batteries don't leak, hard part is figuring out which ones :)

[@whatchacookin1096]

That's what I was thinking.

[@mongi4435]

Never before have I been so happy to hear someone count 1 to 7 ...and stop :)

[@LyonsArcade]

lol It worked out pretty good :)

[@DavidWilliams-rn6uq]

Hey Ron - here’s another neat trick for you. When you have traces shorted together, measure the resistance between them in several different places. With a good voltmeter, you will get a lower resistance CLOSER to the short. I see that you read 0.3 ohms at the ROM chip, I’d bet that you would have read lower at the CPU, then even lower at the external header. You wouldn’t believe the ridiculous tiny shorts we’ve found on newly manufactured boards using that trick.

[@LyonsArcade]

I've heard that before but I've never tried it, I'll have to try and remember it next time, thanks!

Suggest using desoldering wick for the long edge traces- run it around the edge, tack it down wherever copper offers and do the whole edge in one run. Looks nice- no stripping hookup wire and so-on. +1 for your vinegar/water/alcohol method, alcohol works great to take the water out of the board, I use that when I wash circuit boards from stereo amps before repair them.

some how the tv show Macgyver come to mind with that one......new episode to build a magical pinball machine out of parts found at an old electronics store

[@PinBallReviewerRepairs]

I always do vinegar and do a wash and alcohol on any boards I have battery leakage on. It actually nautralizes the alkaline and makes sure that any leakage that might be in the through holes is neutralized and gone. If you did not do the vinegar step you could be back repairing the board as the alkaline has started back up again and eaten up stuff again. And it is a crapshoot with damage that bad it could cost just as much to repair the board then to just get another board. As I know some board repair places can charge a premium for repairing a board. And I just had a thought though that it would be cool to get a board kit for something like this board and put one together. Would be really cool if there is any one doing pinball board kits for the bigger boards? I know there are the do it yourself kits for displays. :) Now I kinda want a big hefty board to put together on a stream now. xD And what people telling you ya aint doing it right? Pretty much get that on a daily basis and yep pretty much give a silly well yeah I know that just let me get to it kind of response. xD

To me it isnt the price, using the original board just seems right with this machine. It was great to see it get to this stage. Look forward to the next one.

Thank you Brendan, we appreciate it man... yeah I mean I like the idea of it saving money, but the main thing is I just enjoy saving stuff. So if within reason we can get the original style board or whatever working in it, why not put in a day's work or half a day's work and make it happen. Now down the line 1 more old board is still around because somebody took the time to work on it a little bit.

That's a really good point - would a small desktop sandblaster not be a great investment for just cleaing up boards like this without having to pull components? Apparantly you can get them for under a $100 of your hard-earned. I mean - who wouldn't want one of them? Brilliant fun to use.

[@LyonsArcade]

It might be a good idea, I've never really worked with one but if you had a small airblaster type thing to get on it it would probalby work well. I don't do enough of them that it's necessary, I usually only do 1 a month or so.

Why does the flippers coils have to need that big Flipper RELAY on the power supply board? Why would a "bead blaster" help clean up the PCB board from hydrochloric acid damage? The What is the IC chips that is next to the RAM chip doing to the RAM chip because you mentioned they work together because not sure that that IC chip does.

[@DavidWilliams-rn6uq]

The 5101 RAM is a low-power device, it provides 256 4-bit locations. The pinball manufacturers used it because it only consumes 10 micro amps (uA) of current when in standby mode - thereby being well-suited to being held up by a battery. 10 uA is a TEEEEENY amount of current, people.

[@LyonsArcade]

The reason they use that flipper relay is because the power to the flippers is continuously on, but controlled by the flipper switches.... so they want to be able to turn it off when they want to. So the other solenoids only turn on for a split second, but the flippers have to stay on while the game is credited up... so instead of using a transistor to drive the flippers and be turned on and off by the flipper buttons they just use the transistor to turn the relay on, which means power is always there whenever you hit the button. There's no hydrocloric acid damage on these, it's alkaline damage and the corroded parts need to be removed so a bead blaster would be good at that... The 5101 ram next to the other ram works like David said, it's a battery backed chip designed to save the settings and the high scores.

[@waynegram8907]

[@GeneralTsosChix]

Is there a reason you don't use copper tape for those heavy ground traces? Many of your videos I've noticed that you lean more toward long solder joints instead.

[@LyonsArcade]

Well there's several reasons, the copper tape can touch other things which would be a problem since everything's exposed.... it needs to be shaped.... you have to purchase it.... the ground trace runs all the way around the board so the trace is only running to a few components and doesn't necessarily need to be thick.... I have solder in one hand and capacitor legs in the other so it's easy to use what's at hand... It works..... it gets rid of literal trash that's laying around (the capacitor legs)... you often have a cap leg already there because it's sticking through the hole so it's easy to use it as a bridge... I just don't see any reason to buy copper tape and then sit around waiting on it to get here, when I can have the board fixed in an hour with what I already have and it works fine, doesn't cost more and all the reasons above. to me it's as weird as somebody (you're the 10th person today to ask this exact same question)... it's as weird as somebody saying "Is there a reason your work bench is brown????"

[@GeneralTsosChix]

Toothbrush, bicarbonate of soda and a dab of water. Neutralises any acids on the traces and is abrasive.

[@LyonsArcade]

This doesn't have acid on it though, it has alkaline which is a base so you have to use the vinegar instead of the baking soda

[@thepvporg]

​@@LyonsArcade Bicarb neutralises acids, unless the cell on the board was an alkaline cell, the cell will most invariably be an acid based electrolyte, most PCB based battery backup's are. If you wet the board and dab a few grains on the board and it fizzez, then you have acid battery. Cleaners I use... IPA, Lab grade Alcohol or Lab grade Acetone, most of the time its IPA because Acetone and lab grade alcohols are hard to come by here. Every board I have dealt with had had a battery backup that leaked, was an acid battery.

Also TVs are pretty cheap, few people are going to spend £200 on a clone board when a new TV costs £300.

After that it takes very little sanding. I would also go with NVRam on these and Bally boards.

O.K., I'll stop doing it, thank you for your criticism
