    A very long time ago, I used to work on the Chance-Vought (LTV) A7-E aircraft. It was an attack aircraft that used (for the era) some very sophisticated avionics. I worked in the intermediate repair department (not the depot repair), and we used to get first time try to repair units (black boxes) that had failed in the aircraft. This is a tale of a tantalum capacitor that became a diode. Yes, you read this right. Most of the failures of tantalum caps is dead short. When they fail they usually take down a rail and are pretty easy to troubleshoot. But this tantalum was in an A/D converter that was pretty much driving us crazy. Finally, the night crew carefully unsoldered the cap, allowed it to cool off, and did a front to back measurement with diode check. Polarized normally at 15vdc... it was a cap. Charged and discharged normally. Reverse, it was a diode, with a forward bias of silicon diode> 0.6vdc. At 25 volts, forward measurement would charge up the cap, then it would short. Reverse at 25volts, it would be open. Strangest thing I have ever seen.
    The moral of the story is, NEVER TRUST A TANTALUM capacitor. I'd change them all out for new ones.
    I enjoy your channel very much, Adrian, and thank you for a great video!! Cheers and HAPPY NEW YEAR!!

      Tantrum capacitors...
      On some old arcade boards I came across a few Tantalums that were turning into Randomness Resistors. For measurement, I use my Testofon which has a 4V potential between the probes and then converts current to frequency on a speaker.
      [What's a Testofon?]It will then upload its firmware to your brain which lets you measure not only wires and broken wires, but also resistors, capacitors (capacity AND leakage), diodes and to some extent inductors.
      Every resistor has a specific frequency. Every capacitor has a specific frequency curve. And I freaking love this thing![/What's a Testofon?]
      These Tantalums made the Testofon play a weird melody... they were all over the place (which also caused the machine to sometimes work).
      (translated: These tantalums had a leakage current that translates to a potentiometer someone randomly turns between 100 Ohms and around 10kOhm)

      @@cowsgomoo4618 LOL!!! I love that plane. I remember walking on the hanger deck of the USS America (Don’t Tread on Me!) and seeing all those Corsair II’s sitting there with huge pans under them. I asked an ADJ why and he told me, “If the pans are empty of hydraulic fluid, the planes need to be refilled. If there’s small puddles of hydraulic fluid in the pans, they have plenty of fluid.” I learned later that the hydraulic systems seal themselves during flight. Strange design.
      The Corsair II could carry twice its weight in armaments. It used a digital computer made by IBM that was the grandson of the Saturn V’s guidance computer. The inertial navigation gyros were made by Singer-Keirfott and were so accurate they could measure the Earth’s wobble.
      That was one damn good airplane.

    That's the preferred method of getting those capacitors off. You push down and twist. Worked with a guy in the broadcast television repair industry that probably replaced 50,000 capacitors a year and this is how he did it. Never damaged the traces.

    • @adriansdigitalbasement

    • @bnice7
      @bnice7 3 ปีที่แล้ว +2

      When capacitors leak, they release electrolyte. The electrolyte is alkali, which is corrosive. The corrosion seeps into the pads and traces. The effect is accelerated when current is passed through the circuit. Because the pads become fragile, that is why the twist method is not recommended. It applies unnecessary force to the pads which can cause them to break. Heat + activated flux helps to remove the corrosion and free the legs without force, giving you a better chance at not causing damage. The brown/black stuff you see from the activated flux is all the corrosion being washed away from the metal.
      That said, I've lost pads using hot air before. Sometimes they're just too far gone. Do whatever method works best for you, but it's best to know and be prepared for trace repairs as these computers continue to age. The surface mount capacitors from this era were particularly bad.

    • @pmgodfrey

      @@bnice7 -- Preferred method in the industry is twisting. You push down on the capacitor with a force and twist. When you do that, the leads break at the board. It only takes 1/4 turn. You don't have to spin it around all day.

      @@pmgodfrey Probably a lot more efficient to do it that way, which makes sense in an industrial setting. They probably just toss the board if they do lift any traces and move onto the next one. As a hobbyist and collector, I prefer to treat my own equipment with more care and pay more attention to the science. Using the twist method, if the leads are stronger than the corroded pad, you'll lift the pad 100% of the time. I'd personally rather apply fresh solder, flux and heat. It's a longer process, but less chance of causing damage in my opinion.

      Absolutely true, tantalums may not leak, but when they fail and cause a direct 5V power rail short you will have even more issues then before! Much better to replace with 1uf, 25v nichicon caps so when those fail you only have to replace a capacitor!

    Hey Adrian, just wanted to thank you on your video.
    I got a CC that wouldn't turn on. Did regular recap and cleaning. And it wouldn't turn on. After a lot of researching (I also got to those schematics eventually and they're so helpful!) I almost gave up on this board.
    Went trace by trace on the U7 and U8 chips, checking continuity, and couldn't find the fault.
    Today, by completely random chance, I saw your video.
    Somehow I missed trying connections that go to J13-10 and J13-14. Lo and behold, the connection from J13-10 to U8-2 was severed. Did the same fix as you, and now I have a happy CC that turns on!

    Hi Adrian. Some notes:
    1) the Performa 475 motherboard also requires the PRAM battery, so you’re not alone.
    2) IIRC, those batteries are 12v, not 3v, but check the documentation, first! Never mind; you schematic shows 3v.
    3) when you were showing the board with the caps off, it looked like one of them, the trace was corroded off (nearby). (@16:42, if you look just under and to the left of C11’s (+) pad.)
    4) it looks like the motherboard is missing an IC (there’s a PLCC socket, but no IC in it.)
    5) a “real” 68040 (as opposed to the 68LC040) has Floating-point registers and ALU, but runs hotter; I recommend a peel-and-stick heat sink at minimum - just be sure it has clearance when you put it back into the case!
    6) while tantalum electrolytic caps don’t leak, then can fail dead short; measure resistance across the power rails.

    On most beige Macs, Cmd-Power is an NMI. You can usually type ES to return to the desktop if you invoke it unintentionally during normal operation or type G FINDER to try to get out of a crashed program and return to the Finder and save your work before restarting. The latter doesn't always work, though, especially if there are larger problems beyond an uncooperative program, in which case you can try to type RB to reboot if the system crashed hard and won't go back to the Finder. You could also install MacsBug where cmd-power brings you to the MacsBug debug screen from which you can view debug info and input advanced commands or return to the desktop via either of the previous methods (assuming the system hasn't crashed, in which case MacsBug shows you a huge screen full of debug info for review).
    On the CC and other AIO Macs, the sound amp is on the analog board, which also likely needs to be recapped. If you have sound problems regardless of which logic board you try, it's likely that you either have a problem on the analog board or something between there and the speaker (the wire is really long; maybe you nicked it?).
    Your Mystic upgrade board will require a VRAM SIMM before it will work, just fyi (it has none onboard unlike the CC or CCII boards). You have two options for the Mystic mod procedure: the quick and easy way with a simple logic board mod to enable it to use the CC's 512x384 display (by default the 575's LB runs 640x480 which is incompatible with stock CC), or you can do a hi-res mod to the CC's analog board to enable 640x480 resolution on the built-in display. The hi-res mod will follow with any subsequent logic board using the 640x480 resolution (including the stock board) with no further mods, unlike the 575 LB mod which would only affect that particular board. It kind of depends on how invasive you want to get and if you want those extra pixels.

    If you still have audio issues, definitely look at corrosion around the sound chip, U5 as it's common for that area to be a problem with the 4 caps that are around it.

    I will add Mac colour classics are very picky with boot up when you pull the motherboard out and swap batteries. I went threw the same problem you had. But I read somewhere you have to let them sit for a while with the battery installed. Mine wouldn’t turn on with a new battery for quite a while. I let it sit overnight went and hit the startup button in the morning and it started right up.

    command control power was the reset command for most of the beige macs- this was the standard way to reboot after a hard freeze all the way through the 90s. I’m pretty sure it persisted through the later macs until they removed the standalone power button from the keyboards in the 2000s.

    One of the best ways to check a board is to take diode, resistor measurements on each pin of all IC and components. Taking the positive to GND and the negative to the test-point.
    This technique is used by most of the Flying probes to test boards.
    Sure you need another board to compare it.. but sometimes even without that you can figure out the problem.
    It was better to take out the oxidized chip and clean it and replaced again to see how much was damaged.

    It's always great to see your Macintosh themed videos! I have a troubleshooting suggestion for you: I have found that with many Macintosh boards the electrolyte from the capacitors sometimes leaks underneath the ICs. This fluid can cause the ICs to behave abnormally. There may still be a bit of leaked electrolyte underneath this particular chip. I think it might be a good idea to try pulling the IC, cleaning underneath it with Isopropyl alcohol, and soldering it back down. I couldn't quite make it out in the video, but I know that with Mac Classic II's the chip that is worst affected by this fluid is called the Egret chip. I look forward to seeing more videos about this computer!
