Culprit might be your horizontal vertical deflection coil connections around the CRT, and perhaps the capacitors near the deflection IC on the power supply board. Be sure to discharge the CRT to ground though, because it itself acts as a large capacitor.

I loved the end, it's what makes your channel stand out from numerous other computer channels on KZread. Loads of them tell you helpful or interesting things, but with no soul, no fun aspect. Then others like druaga1 go completely the other way, providing little to no technical information at all and just ... messing around very comedically for an always unexpectedly long amount of time. But your channel takes the middle road: it's full of exploration and discovery, yet also technical information that fits around the beautiful plot you tend to create for each of your videos. As a nerd, I enjoy channels from the whole spectrum in this regard, but I especially find your videos easy to watch. Keep on keepin' on.

I’ve always targeted that ‘middle of the road’. I’m glad you see it. Thanks for writing.

The problem is most likely on the analog board, and may have been accelerated by the unexpected resolution forced on it by the mystic board. The weird light patterns on the screen when the mystic board was in place were caused by the electron beams not being deflected to the right places on the screen, particularly regarding the horizontal positioning. At the left edge of the screen you're seeing the result of the beams getting squished together because the deflection coils are pulling too hard on that side and the beams are going to the same spots on the screen at those points in the horizontal sweep or even reflecting off the sides of the tube. The main cause of this is unexpected timing from the video signal (like forcing a 640x480 signal onto circuitry expecting 512x384), which is why going back to the original motherboard re-centered the image. The vertical flickering seen after putting the original board back was probably caused by an instability in the control circuitry that was made worse by having to deal with the unusual refresh rates. Capacitors are often the first things to go in situations like this, so replacing the ones on the analog board will likely help. Also double check the solder joints for signs of loosening or cracking, I do find it interesting that the screen actually shows a proper picture briefly during the shutdown process, just before the system turns off the display output. Could be a sign of a voltage regulation problem, which may be related to the flyback transformer as well, which is going to be a bit harder to find a replacement for.

The batteries are regular (non-rechargeable) Lithium batteries, not the more dangerous Lithium Ion or Lithium Polymer batteries that can cause fires if either overcharged or drained too far. Also, the batteries used on the Mystic and Mac TV boards are regular Alkaline batteries, unlike the more common 1/2AA 3.6v battery like the Color Classic's original board has. It is possible, however, that they can leak onto the motherboard, corroding various contact points or eating away traces. They also will last far longer if not being constantly drained by the clock circuitry and maintaining the SRAM used for storing the PRAM data. So if you're not planning on using a particular mac for a while, you might as well pull the battery out and deal with resetting the clock and other functions the next time you plug the Mac in. On a somewhat-related note, certain Macs will not power on at all if the battery is not installed or is completely dead, though this was more prevalent in the PowerMac lines.

@@ComputerClan Some Macs don't boot right without a PRAM battery, like the LC series and the original Mac II. The Color Classic should be okay without one. Those red Maxell batteries are ticking time bombs, though. It's a small miracle that the one on your CC board hasn't leaked yet. I think your analog board probably needs to be re-capped. (Spoilers!) The weird glitching you got looked like the logic board was trying to feed the analog board a refresh rate it didn't like. IIRC you have to do a hardware mod to the logic board to make it put out Color Classic friendly 512x384@60, or mod the analog board to accept 640x480.

Re-cap the analog board.

I've fixed half a dozen beige Macs this way, the problem is just the age of the capacitors.

17:17 welcome to Macintosh!!

At certain points I can see a good raster in the flickery mess, centered correctly and everything. Since that logic board doesn't work right I bet it's putting out a bad sync pulse so the monitor flips out. It's stable but off centered with the other logic board so I really don't think the monitor is the issue here. Used to work on these machines yeeeaaaars ago. Give the correct logic board a recapping, clean it thoroughly, etc. It'll probably work afterwards.

The same thing happened to the 8 bit guy's Hyperion computer, it just needs recapping, especially since this was a 90s Apple product 😆

The 'Mystic' board is an LC 575. The Color Classic 10" display was 512 x 384 and the LC 575 was 640 x 480. Modifications are necessary to get the 10" display to operate at 640 x 480. Usually a dead PRAM battery is the cause of the start up failures.

I would legitimately love to see a Krazy Ken episode where you just make a movie where you find classy.

It’s the analog board more specifically, the flyback transformer for more info, check the book “dead Mac scrolls”

I dont know why, but that last part where classy went made me cry.

Did you ever reset the PRAM (Command+Option+P+R) at startup? That would typically reset resolution settings, as well as a few others.

As soon as I heard about the issue of the flickering CRT, I knew it wasn’t a logic board problem(the booting issue probably is though) it’s an issue with the analog high voltage circuitry of the crt.

I cracked up when you couldn't find the port for the powerbook.

charging them has worked for me as well

Sorry for your loss :(

Almost there. It looks like the magnets are gone in the CRT or possibly the caps.

there's probably a problem with the CRT driver board. the hissing and buzzing either means a short from corrosion, or a bad capacitor and maybe both. i'd have to see it in person, or through discord, to see what the culprit really is. it also could be the deflection coils, they too might also have been blown or shorted.

LOL. Complete misadventure, I love it. Complete cap replacement is mandatory for these models. You can see it in the first few minutes of the video, the brown crud near the battery that you were talking about could be from the leaking caps. Recap the logic board and the power board and it might work. If you don't want to do it, send me a message and you can send me the Logic board and I will recap it for you for the cost of shipping.

If you haven't replaced the PRAM battery already, it should be. Old World Macs (pre blue and white G3) will not power on if the PRAM battery is dead. They used a 3.7v lithium battery that would charge when there was power. After a while, they fail and can't hold a charge anymore, which means the board can't retain the settings on what hardware is present and how to interface with everything and boot.

Captiotors, its that most likely, however there is a chance that the screen driver might have an issue this happened to me with my MacBook Pro and even though it’s newer and way more powerful once I connected it to a different displayed started working normally I recommend resetting your entire computer to Noob even though you have an external hard drive it might be messing with its logic board which would explain the flickering there’s been. I recommend just a clean install and see if that fixes it if that doesn’t then will we all know the issue.

My Centris would have never done that.

So the mystic mod takes a higher screen resolution than the internal Sony Trinitron CRT can natively handle, it takes a mod to get it to go from 512x384 to 640x480. There's more about it here: powercc.org/640x480/

Looks to me like the display driver and power board has died and as it is right above the main board it looks like it has leaked some kind of life juice all over the place. either replace or re cap the board? As for the old main board that needs a proper clean and new caps and possibly other components. If you had plenty of time for it to be fixed I would take care of it for you.

Collaboration with the 8-bit guy?

It's the psu for sure, the screen was flickering and it stops flickering for like half a second when the hdd is being accessed (aka psu providing different voltages to the computer), so i think it's the psu, you should have started with that in the first place i think

I think the issue is that some part of the display is getting too much power. When he flipped the switch to turn it off for a split second the image looked normal and filled the whole screen.

It could be a display connector that could be fixed or cleaned.

I think it’s a dead power supply, capacitor in the screen, or dead video chips on both logic boards but the third is highly unlikely

maybe just maybe the crt did not have sufficient electricite when you put in the mystic board,resulting into the display low power mode But when you put the old board back in it to so low power that it shorted a capasitor

How dare you make me feel feelings Ken

Also i think you should try the CMOS reset button on both of the boards. Its a tiny button on the boards

Could be a bad connection with one of the wires internally I am not to familiar with Macintosh classic models but that would be the easiest issue to fix

I once had to (on a Linux computer) blindly control alt f1 to go to tty1, enter my username and password, then type sudo shutdown now end enter my password again, and after ten minutes, I did it again as it did not work the first time, and after another 30 seconds the computer shut off!

Power surged the analog board. Caused it to leak and then the screen panicked

It could be the chip that displays stuff on the screen

22 minutes of 'diagnosis' - and a recap of the boards would take about 35 minutes and likely fix the problem.

Remove the PRAM battery and scrub the logic board in the sink under warm water with a toothbrush and let it dry thoroughly, if it temporarily works again it needs a recap, if it still flips out you might have corroded broken traces and those will need to be beeped out with a multi-meter and repaired.

Ken, take my word for it, the capacitors on the logic board have leaked their electrolytes out and have possibly damaged traces on the board. At 3:26 you can see that there is corrosion around a capacitor (C80?). The caps need to be replaced and that should solve it for a while. It's the same thing that happens to the display of a Classic or Classic 2 (just do a Google for Mac Classic jail bars). Every time you power up the CC it's just going to get worse. I have a Classic that I have to have done, but mine isn't so bad... yet. There are reputable practitioners on ebay that will do it for about $80. It should make a good follow up video. Good luck.
