I didn’t realize there was a standardized color code — thanks for pointing that out!

Hey everyone, I accidentally broke L1 on an SE logic board. I'd like to order a replacement from Digikey — does anyone know what the part is, and what the value is? It kind of looks like a resistor, but something tells me it's not a resistor.

@LaPorta I am the same. I do a mean recap, and try to be as proactive as possible about replacing components that are known to have a high failure rate. Anything more than that, though, and I have to ship it out to someone with actual troubleshooting and repair skills.

Does anyone know if any progress ever happened on this project? It’s a really cool idea that keeps popping back into my brain every month or so, but I have none of the skills necessary to contribute.

Hmmm.  If there's no glow in the neck of the tube then you have issues with your heater voltage.  Not sure if that is connected to the flyback or not.

Are you sure you need a new flyback?  You mentioned that you can still hear the high voltage "zzzzt" when you start the machine.

@PowerMac_G4 I saw your post about that in another thread — I'm sorry to hear about what happened! I googled the LG part number (6174z-1003g) and found that there was a replacement from HR Diemen.  HR Diemen was a well-known manufacturer of flyback replacements back in the day.  When I found...

Where are you located?  You might be near a forum member who would be willing to help you out.

More thinking out loud — I wonder what is considered an acceptable tolerance for capacitor values?  And I wonder how your capacitors would read when tested for ESR and current leakage (not physical electrolyte leakage). Badcaps.net had a pretty active forum about capacitors years ago.  I'm not...

What an incredibly thorough deep dive into the current health of your machine's capacitors — this is fascinating.  With all the debate about recapping in this hobby, actual data like this is a big step in the right direction. I don't know how to interpret your findings, but, on my iMac G3...

@PowerMac_G4 I replaced them all.  My philosophy of capacitors is that it takes more time and work to pull, test, and re-install than to just replace.  And since they’re a wear item anyway, I see a full replacement as good preventative maintenance if it’s a machine I really like.  That way they...

Did LG do the monitor part on these? If so, I'm not surprised to hear that the boards have awkward layouts and oddly-placed shields.  That was my experience doing a full teardown and recap of a trayloader iMac too, where the monitor and power supply are LG.  I was able to complete a full recap...

This is fantastic!  I've got SCSI2SD in most of my Macs, but man do my machines feel sterile without hard drive sounds.  I know there was talk on this forum of creating an "HDD sound" generator a year or two ago, but I don't think the project went anywhere.  I'd love for my SCSI2SD macs to whir...

I agree, it's going to be really neat to see them all together in one place! Daniël, I would be happy to share my capacitor list with you.  The only caveat is that as far as I understand, there were two revisions of the analog board and power supply for the trayloader.  (This is not to be...

Hey everyone, I've just wrapped up what ended up being an extraordinarily involved project: the full teardown, recap, and restoration of a G3 iMac trayloader.  She's a 266mhz Tangerine, and she's a beaut: This has been one of my most involved Macintosh projects to date, and the only thing...

There were external boxes that allowed you to display a Mac's DB-15 video output on a composite television.  Could this be the PCB from one of those boxes? A DB-15 passthrough and a composite out for hooking up to a large television?

Update: I completed the tube swap and it worked well!  The tube from a G3 All-In-One ("Molar Mac") fits the trayloader iMac and seems to work well. The tube from the AIO is missing a small, three-pin connector that the iMac tube has.  It seems to work fine without this connector — no idea if...

Hey everyone, I've got a trayloader Rev. C iMac, and I just acquired a new-old-stock picture tube for the G3 AIO.  My plan is to put the AIO tube into the iMac.  Has anyone ever swapped picture tubes between the two?  They are both similar part numbers from LG, but don't seem to be exactly the...

Nice job on that recap!  It looks nice and clean, and I really dig the way solid polymer caps look on these boards  8-) Do you have access to a working Classic or Classic II that you could try this motherboard in?  It’d be good to rule out the analog board. No idea about the RAM jumper.
