    Macintosh IIsi Power Supply Diodes

    Multiple components fell off my card when cleaning and recapping. Is there a possibility of bypassing this card and have the computer power on without the button?

    Ah, thanks for the heads up. I think all signs are pointing to the swim chip on my SE 30 restore. I may just poach one from another II or IIsi.

    Interested in 1 of your swim chips Kai, part number 344S0061-A if you still have some.

    Unable to center horizontally after Color Classic Re-cap

    Fixed update: I went on a wild goose chase and it paid off. Traced the pot on the underside of the board testing all resistors. This little dude measured 9Mohms. That can’t be right. Found a reference guide online (which can be wrong btw) that said it should be 1k ohms. Used the rework...

    Unable to center horizontally after Color Classic Re-cap

    Re-glued the inductor back together, reinstalled and same issue (I didn't expect anything different). PP1 isn't easy to get to so I'd rather set it using a MM once someone is able to provide a solid reading.

    Can someone with a CC board tell me what the reading on PP1 is, I have a feeling this is related based on a section in https://powercc.org/640x480/

    Unable to center horizontally after Color Classic Re-cap

    This may or may not be associated but I noticed this inductor (located at LL2) came off it's glue/base and was very wiggly, it is somewhat close the yoke connector but I have no idea what it is. I'd figure replacing it couldn't hurt but I don't know what it is or what the 95 represents. My...

    Unable to center horizontally after Color Classic Re-cap

    Removed the pot for centering horizontally, it measured appropriately out of circuit. Could a load affect the pot? What components control horiz that I can test?

    Unable to center horizontally after Color Classic Re-cap

    Hello, I recently performed an unsuccessful recap on the analog board, when I powered on RL54 started to smoke so I turned everything off. Recently I re-checked ESR on all caps, triple checked polarity, replaced the 30 ohm 4w resistor on RL54 (there is some confusion here as the fried resistor I...

    Color classic AV recap booted first time fine

    Well, I tried the 330ohm, and it also smoked so I turned it off. I think now I will try to disconnect as many things as I can and add them one at a time. I do have a AV board for a performa 579 so I can poach some parts but because it was a bigger screen a lot of items will not transfer. I'm...

    Color classic - Replaced caps -> clicking analog board

    Hi, I see RL54 as 30ohm 1w on https://powercc.org/640x480/ otherwise it's listed as 330ohm as stated above. I'm looking to figure out my issue listed here:   any thoughts?

    Hi all got my resistors in. What would be the best place to start 330ohm or 30ohm? :)

    Color classic AV recap booted first time fine

    I found one doc that said RL54 should be a 33ohm resistor: https://powercc.org/640x480/ a few others state 330ohm, can someone give me a definitive value? Based on the color code of the original I see it as a 33ohm, I’m not a pro at reading color codes btw. Also will a cooked resistor measure...

    Color classic AV recap booted first time fine

    Hi everyone, I did the painstaking analog video recap on my color classic verified polarity multiple times and thought I was in good shape because the computer booted up without any issues. Today I booted the Mac again and got a bouncy pin cushion shaped image that looked like it was shifted to...
