    I recently came across this Commodore Amiga 1080 monitor that was dropped or suffered some type of severe impact. It had lose parts inside and was reportedly "totally dead." In this video, I bring it back to life!

    I always preferred to remove the solder mask all along the crack. Then using solder wick if possible to bridge over the crack. This provides an electrical connection, some rigidity and some flexibility for the board. If solder braid is too large for the trace, then use the largest gauge of hook up wire that will fit. The reason for doing it this way is to make sure I don't miss a cracked trace along the crack. And finally ohm out all of the connections!

      I agree. Solder braid is also my preference. Off topic but solder braid has a bad reputation but is my preferred method of de soldering components too. Ppl just don’t know how to use it any more. They try some old crap that’s been laying around and the flux in it is long gone and think it sucks. If anyone is of this opinion i challenge them to apply a drop of fresh flux on the braid before use and it will remove just about any amount of solder on a solder joint like a breeze.

    Another note for those playing along, you should never push on the neck board from the anything other than the center of it. Pushing from the edges, you risk cracking the neck board and you'll be doing a lot more jumpering. All those who have suggested doing epoxy and just scraping the mask off and soldering right at the crack are correct.

      Was think the same thing myself as it would help reinforce any gluing afterwards.. I'd also use thicker (solder adhering) and longer metal pieces to bridge the thicker traces as it would help reduce strain and help stop the "bridging" solder from flexing.

    Hey Adrian, do you know about "fiberglass scratchbrush"? They're a rod of compacted, parallel lines of fiberglass in like a lipstick container. They work great for removing corrosion in tight areas, but also for removing soldermask without damaging the copper underneath (unless you REALLY work hard). They save a ton of time, just gotta wipe with a napkin every few swipes (or do it under alcohol) so the fibers don't go everywhere as they break off. Super useful stuff for doing rework, and dirt cheap (most pens come with a second/spare fiberglass rod in the handle)

  • @donoester6744
    @donoester6744 2 роки тому +2

    Regarding the ripple: Look for a small value capacitor in series with the horizontal scan coils. It is likely in parallel with a resistor. The purpose of this is to create an LRC circuit to counteract ringing caused by the inductance of the energized coils at scan frequency. The ringing effectively means that the cathode beam(s) are moved at a non-constant pace, causing small ripples in brightness. Since many of the traces around the flyback have been repaired, you're also affecting the "ringing" to a small degree as well.

I did find the interpretation of the schematics in conjunction with the oscilloscope educational, though, because CRTs aren't trivial for a novice retro repair enthusiast.

  • @telemedic5142
    @telemedic5142 2 роки тому

    Great video, good result. Just a point about auto degauss posistors. The idea is it’s low resistance when cold, and applies a voltage to the coil that diminishes as it heats up. You had powered the monitor face down, and although the flyback was not connected, the degauss was. Degauss happens with respect to the earth’s magnetic field. So if it degaussed face first, and the posistor stayed hot, no further degauss would occur. This means as you sit it back upright it’s no longer degaussed with respect to the earth. Leave the set off for 15 mins or so, then try again. I also recommend to use some epoxy resin to fix the the cracked pcb and stop and further spread. But that said, well done. Another one saved :)

But hey, what do I know :)

      I agree with patching up the wide traces with some solder braid, but _also_ leave the jumper wires in place and only rely on the solder braid for mechanical reinforcement. Then you only have to patch the wide ones, there's no mechanical point to patching something half a millimeter wide.

    Nice repair, but you made your life harder than needed. Use a small drill bit to stop the cracks at the end. Stabilise the pcb temporarily with hot glue. Then use those fibre glass pencils to remove the solder mask, flux the copper and use solder to jump the cracks. Wire wrap wire to jump thin traces. Test, fix anything you missed then Epoxy the crack with non metallised epoxy. As mentioned below the flyback core may be damaged. Shango66 covers this with the self destructing Sonys.

    Seeing that cracked PCB makes me wonder one thing... I am currently working on repairing my 30 year old Sony Hi-Fi, which has a cracked PCB in the amplifier. Since I was able to get the schematics, I am basically recreating the entire thing in KiCad, and then layouting a board that has the same outline and location of connectors and other important components.
    So.. now I wonder if there would be a place where enthusiasts all over the world could simply upload such recreated designs for others to use. Since the schematics for the cracked board in your monitor are available, one could do the same thing, and maybe someone else somewhere in the world could find it useful.
    Well.. just thinking out loud...

    • @mal2ksc
      @mal2ksc 2 роки тому +1

      It seems most people who bother KiCAD'ing up a PCB end up buying some from PCBWay or similar, and they allow the option to let others look at and use your design. This is going to be fragmented, each circuit only being on the server of the company that ran the boards, but it's better than nothing. Also you have a lead on who to contact if you get stuck -- chances are the person that uploaded it has built at least one by the time you see it.

      At the same time it is probably pretty risky as you have to mention the original manufacturer and part number in order for people to be able to find those designs. And I don't know how companies like Sony would react if someone offered a compatible replacement for one of their PCBs, even if the product itself was phased out 30 years ago. After all, that company is still in business, unlike many of the retro computing manufacturers.

      I also didn't like him repeatedly adding wires to the same point. It's fine to have a star pattern, but you want to make sure you have one solid solder joint going through the whole stack, which you won't if you keep stacking new ones on top. However, given the severity of the damage, I think that an event that causes that janky solder joint to fail will likely _also_ cause further cracking of the board that will require repair, so it's not worth going back in there to clean it up now.

    I'd have to say, for never doing a static convergence and the purity magnets before, you did an excellent job, sir!

    I would have scrapped the solder mask off on both sides of the major cracks, tried to flatten out the PCB so the cracked ends came back together, and then flowed solder to bridge all the breaks and hold the board back together. Would have then added the heavy bodge wires.
    If that monitor is NOT a Trinitron or similar one gun inline tube then there should be a set of rings on the yoke or neck of the tube that need to be rotated to set purity. This applies to the triad gun (RCA) type of tube. If the thing was dropped those rings could have shifted.

    Those monitors were great value for the money. I remember using one as a TV, as we had a miniature B&W TV (with like a 3.5" tube), but it had composite out. Ran that into by 1084, and we had color TV instead of B&W, and you could actually see what was going on!

      Amstrad (one of Commodore's big rivals in the U.K. actually sold a Tuner box to convert their monitor into a TV. I was going to suggest you could also use a VCR, but back then they cost more than a C64 and a TV together.

    This has been a seriously helpful video, thank you!
    I've got a nice Tatung multifunction (MDA, CGA, EGA and VGA) monitor that has/had exactly the same issues. It took a nasty drop during shipping and the flyback cracked the PCB. Fixed that and despite my better judgement, did a full recap as a couple were giving issues.
    But it had colour purity and convergence issues almost identical to whats seen here. I had written the tube off as damaged, and it is in bits half way through a tube swap currently, but having watched this, I'll be reversing that and having a more in depth play with moving the yoke and purity rings.
    I cannot overstate how much I have learnt from your channel, it is absolutely one of the best out there.

      I had an SVGA monitor take a tumble down some (fortunately carpeted) stairs, and although it didn't quit working, it got _way_ out of adjustment. I was hesitant to work on it, not because I didn't know how, but because I had done so enough times to get thrown across the room once. I remember doing a lot of the job with paper tubes and chopsticks. I never did get the convergence completely corrected in the corners.

    So that black soot is a sign of high hours? Found some in the 1995 Apple color 14" monitor I cleaned up recently.
    This is the kind of repair I enjoy, bodging busted bits back together! In some ways, the easiest kind of fix.
    Funny thing, the first time I turned it on I got a power LED and a screen-flash when turning it off, but after plugging it in to my Performa 475 it wouldn't show any activity, not even power-LED, unless the Mac was also on! Weird.
    This Amiga CRT is still in better shape than my Amstrad-clone monitor/power-supply that was EOL'd/stripped for scrap by the PC shop somebody dropped it off at!
    Huge holes in the case, heat-sinks ripped out along with their attached components and chunks of the PCB!
    Still fixable, I think, as I have the schematics, just need to find some rare/obsolete replacement parts.

    Some of the early 1080s had longer-duration phosphor which meant that interlace was virtually flicker-free, particularly compared to, say, the 1084. There are obviously plusses and minuses to that but the first A1000 owner I knew got his monitor and system _incredibly_ early and my god, even interlaced mode was beautiful.

    That red wire is monstrously thick, but it's probably the right choice in this case. For low voltage low current stuff I typically use wires from a high quality Cat5e Ethernet cable, their insulation is rated for up to 125VDC. For low voltage high current stuff I use automotive wire rated for 48VDC.

    • @mal2ksc
      @mal2ksc 2 роки тому

      For low voltage low current in an application where I don't have to worry about mechanical stress much, I like using solid-core telephone exchange wire, because there's no fear of a solid wire unraveling and having a whisker cause a short -- they don't have any whiskers. I remember Cat 3 and some really cheap "Cat 5" cables (that never really worked at speed) had the same solid core wires, but more recent cables don't seem so coat-hanger stiff so I suspect they're not solid core anymore.

    The 1080 is a fantastic display and totally worth fixing. I completely lost the red gun on mine a few years ago, and was worried I wouldn't be able to fix it. Turns out, the digital/analog input switch on the rear was all corroded. Taking apart the switch to clean it, polishing the RCA jacks, and lubricating the pot knobs in the front was all it took to get the monitor working almost like new. I have a flicker fixer in my A1200 "just in case", but I still use the 1080 for a display because it looks great.

    You need to take those rubber wedges out and replace them, they go hard and hold moisture this will destroy the yoke.

RGB is fantastic though. I first discovered this when I connected my Commodore 64 to it.

    SuperGlue! Fill those cracks with SuperGlue and once cured go over it all a second time. SuperGlue's natural wicking action will work it's way into all the cracks and fibers of the PCB and create a very strong bond. Been using SuperGlue for these kinds of repairs for years and it works wonders!

    I would epoxy the board and then remove the paint and solder bridge the traces. Use slow curing epoxy or UV stuff whichever is stronger. Maybe desolder components first for better access. After the repair you could put a new layer of paint on the traces. Makes it look cleaner.
    Since it is only single sided you might be able to make a new board and check and move the parts.

    The ringing could be caused by pick up from the white wires as the pass close to the LOPT( line output transformer).I use to be a TV engineer and a common issue with ringing was due to a damping resistor across the line linearity coil. They would go high in value causing the lin coil to ring which would show visibly on the screen.

    In some materials, such as metal or glass, you can arrest a crack by drilling a circular hole just in front of its path. It eliminates the tear in progress by spreading forces evenly. I would think it would work well on a PCB, if there is room for a hole.
