That could be it! The drive has been cleaned, re-lubricated, re-capped and tested in another Mac (non-color classic). Also, I'd expect the symbol to be a "?" instead of a "X" when there is no drive installed?

Thanks for the additional info! In the meantime I also took out my trusty Tektronix T912 and did some test on the voltages: - Configuration 1: LB out, rear case off. Connected the oscilloscope to the fan connectors on the AB. Powering on the clicking noise returned (at least some consistency)...

Update: So I've now recapped the entire AB and at first it seemed like the CC is able to stay powered on much longer than before, manually killed power after ~10 minutes to put the Floppy drive back in (which I hadn't installed back yet after confirming that it, indeed, works). So I took the AB...

So something like this (BYW36-TAP)? Or am I missing something here?

So I desoldered DP6 to get a closer look and the packaging says: PH BYD34J. Good news: Googling that name gives me a data sheet. Bad news: it is no longer available - though I want to replace it with something more capable anyway, similar to the DL21/22 mod. However, I'm not sure on how to pick...

Some progress: I now went basically over all solder joints (except for SMD stuff) and now the image is "stable" in the sense that it now longer flickers between perfect gray and purple and has no longer the geometric distortion at the top and bottom 🥳 However, the loss-of-power-problem after...

Thanks for all the input! I took a closer look at that. Seems to be just a dent/scratch (see new photo) but, as @JDW pointed out, this diode and the resistor next to it are burned to some degree, so I'm going to replace it (btw, taking a closer look at the image in the CC recapping guide by...

Thanks for the high-res images! Comparing them to images I took a few days ago prior to the component upgrade there is definitely some discoloration on both sides of the board and not just some dirt (though you are right that I should also go over the entire board with some cotton swabs and IPA).

Hi, thanks for the quick reply! Yes, I'll eventually update on how this heat shrink tubing construct holds up over time. Okay, so what I get from this is that for now I should just replace all caps that are still original - is there anything else I could/should replace as a precautionary...

Hi everyone! A few years ago I got a Color Classic that didn't work properly (can't recall the exact symptoms at that point - again, it has been a while...). So I performed the obvious operations: Recapping the logic board with Tantalum capacitors and the more "error prone" caps from the analog...
