Power supply repair and even bonus John's Kitchen interludes, sweet.

Thank you for posting another video again so soon. I hope you enjoy it like you used to and have time to make the videos. I've been going to my John's Arcade support group for the last few months and it has helped with the absence of you videos, most notably the year end review and John's Kitchen videos.

I forgot about John's kitchen videos. Nice to see it back

These kind of episodes are my favorites.

I love how you don't even acknowledge the new popcorn machine. Lol. As far as the power supply goes, I consider all of these videos that end this way a learning experience. That's one of the things I enjoy about this channel. We get to see the times where things don't go exactly as planned and we learn from it.

New popcorn machine? He never broke it, that was just a dream.

Boy I sure miss these weekly videos....they are my inspiration....

New popcorn machine is looking good!

Nice to watch a new video! Went to the Manchester play expo this weekend. Was a pretty good experience and got to play many old classics. It's a shame it was mamed by tons of the games either having no sound, unresponsive buttons/joysticks or just not working at all. They had a deluxe outrun with a wheel with no resistance so you crashed really easily, a deluxe space harrier that wouldnt go to the top of the screen. They need your restoration skills! What was good is that I got to play many games I havent been able to play on mame due to dedicated controls such as tempest and robotron. Pretty cool. It did make me appreciate my pandoras box though. Some of the games i tried did look and play better on my box than on the original cabinets. My purist attitude has been knocked a bit. It did take me right back to the 80s and was REALLY busy on the arcade cabs.

Yes you used my magnetic bowl! Thanks buddy. So glad you are back. This made my day!. Good to see you smoking also. I have a Grilla Grills Silverback. If that Traeger ever takes a dump you can't beat Grillas customer service and the things built fantastic. I have smoked in -5 degree weather and it keeps its temp perfectly and the cost is very good.

Your videos are great. When I saw the grill it reminded me of baking my Xbox 369 board in the oven to reflow the solder to get rid of the rrod.

Good lord I cut my teeth on most of the games you have. Been an arcade tech/service tech/manager for over 25years. (Still doing it!) In the past where it was just the +5 +12 -5 we used to just remove the old linear supplies and mod them over to a newer style switching supply. Nice to see someone dive into the original supply!

Feel nostalgic and claustrophobic all in one spot!

Dude welcome back! I was starting to worry we had seen the MK get rid of ya, I swear I have not seen any videos here since the Final video on that cab. Just glad to see you pop up my friend.

Desoldering tip: leave the tip on the joint for a couple of seconds and wriggle the tip in a circle before hitting the trigger.

Work had set up one of those Pac-Man 1Up's in the break room. They are indeed amazing to play when seated. I wouldn't have thought it until I tried it. And I am glad to see the company isn't backing down from that lack luster Christmas season. Looks like they got some new ideas on the horizon. Like counter top versions and wall mounts. What I am hoping for...a cocktail table model. They do have a prototype of one. And welcome back, John. :)

I appreciate this long-form approach. I must admit, though, I kept chuckling every time this guy almost destroyed his lab station.....like watching a gorilla that learned to solder! You've got my thumbs up!

Awesome vid John mate, I'm starving now though after seeing that meat!

John. the Hakko should sit on the join for a second to let the solder melt properly before engaging the vacuum. it should be enough to run it once. not only is the barely melted solder more likely to solidify in the tube and cause blockages, it's also wearing out faster than it needs to

One quick sujestion John. Test the continuity between the ground and the 5volt pins on the board and see if you have resistance .

Might of been useful to use time lapse for some drawn out parts. Nice to see you back!

New popcorn machine!! 😎

Funny to see you testing your desolations without the vacuum chamber. 😂

Yay new video!!!

with the AR3 voltages correct wasn't really expecting the rebuild to help. having isolated a problem to range of cheap parts shotgunning might be fine but shotgunning the wrong board might just create new issues where none existed. easiest way of debugging voltage drop is probably your finger, shorted component is likely to get hot.

We're back!!

Wow, I think you got more excited about that delicious-looking superbly roasted pork than you have about almost any repair you've done, John, judging by how much more of that Herald Angels Christmas music with the stars, outside of the Christmas season, that you put over this meat, than over a repaired game, haha!

Nice slow motion meat shot and christmas music lol!

Great way to start food brings us all together , so While I was watching couldnt stop thinking about the bbq , love your videos brother , dont you just love how the old stuff is easier to replace , I should do more of this on my channel I know my Silent scope has a vertical collapse problem some tie when I turn it on , good old slap on the side fix's it for now , cheers John hope my channel picks up " Marcho arcade "

By the way. Next time I'm up I will bring the special drill bit to unclog your Hakko FR-300. It's a manual tool that you twist and it cuts through the clogged solder inside. Also, no need to shake the bit when trying to take it off. There are tabs on the side of the grab tool. Squeeze them and it grips it so it slides off. Magic!

Hi John. I think You may have a short on the pcb. If You're getting the 5volts then you have a good power supply . If you have another power supply that you know works then try it out.

it's funny to keep hearing new interpretations for OL. "over limit", "open line", "overload", "open loop". any other ones?

@RotaryTurbo

5 жыл бұрын

I'm not an electrician or EE or anything, but I'm pretty sure the "correct" term is "Over Limit", as in over the limit of what the meter can read. Even through air, there is technically a measurable resistance it's just far outside what a meter is capable of since air is a pretty good insulator. So a null reading is "over the limit" not really "zero". You may find you can measure the resistance of your body, though. :)

I kind of like what John did here with this taking a break and enjoying some other stuff for a minute. That's what my cousin. If you stick on one thing all the time everyday you're going to burn out. Then I don't think any of us want to burn out on this Hobby I love it too much to get burn out on it.

It might be worth looking into getting a cheap thermal imaging camera. There are versions (you can find them on eBay and elsewhere) that plug into your phone (android and iPhone). You can then use them to track down hot spots (and likely shorts) on PCBs. I've used a Seek Thermal for android, which worked well, and those can cost about $200. I think Ian used one in one of your videos to troubleshoot an issue. There are cheaper, generic Chinese versions (look for HT-102) for around $100 as well as ones that don't need a phone (search HT-175) that cost around $150. There's also a much cheaper method of spraying isopropyl/rubbing alcohol on an area of the PCB. It should evaporate instantly wherever there's a hot spot. I've never tried it myself, but I've seen that approach used often in troubleshooting Macbook and iPhone motherboards.

Sorry it didn't work out shotgunning it. When I rebuilt the linear power supply in my Space Invaders I literally had to replace every part in it. You'll fix it. I have faith.

There was an epidemic of counterfeit 2N3055s in circulation at this time, where did you get them?

What if you took a switcher and put 5v and ground to that game board header and see if you still have low voltage reading at your game board test point. That would confirm or remove the A/R-III from the equation, no?

Just a general comment I really enjoy your videos very informative. Just wondering why you dont have a Spy Hunter though, think u need to add that to your collection. Would like to see some repair videos of it.

Your videos are fantastic. Haven't seen a new one in awhile. Everything ok?

Those transistors have been replaced before or they would have the old mica insulators, not the newer grey thermal pads, i would have re-capped the board before even touching the IC's.

Any on the road videos coming up

"I can't keep working on this..." for how long?

Something else is dragging the voltage down, freeze spray or your finger and start hunting :). BTW transistors can ohm fine, but fail when you turn them on (when they starts getting hot), but you have change them so thats not your problem here

Oh my god that meat looks so fricken good XD

He's a passive-aggressive KZreadr. Has nothing but disdain for his subs.

Say, check the 5v again without load on the power lead. Set to 5V power off, then plug it in power on and test from the back of that connector. If the power has dropped it's a good chance you have a filter cap or other components on the paperboy PCB shorted drawing the power down. Sadly this could be nearly any one of the IC on that board. If there is 5v on the connector but not your 5v test point, again the paperboy PCB. Check the traces and resistors on the 5v to that point as something in the path could be burned cracked or devalued. Look for a hot IC, would be nice if you had a flir IR camera or something similar to view the board, specifically the IC for a hot point. You probably have this idea already, but figured I'd toss it out.

How old are those 2 old small e. caps?

Guess who's back... Back again 😏

You should make sure the paperboy video board hasn't got a 5v to ground short on it using a multi meter. You could be doing all this work on the power supply for it to be fine all along.
