SuperMac Spectrum 24 III ceramic capacitor?
Posted by: ktkm on 2020-04-02 12:26:14
The video suddenly became raggedy and stripy in right edges of windows, menus, and other GUI elements (only when displaying millions of colours). Upon closer inspection, I found a blown ceramic capacitor on the back of the card. I thought I replace it, but I don‘t know the value, or where to retrieve it. Where can I find such information? Help much appreciated.

Here is a picture. I tested the traces close the blown capacitor, and they are fine.

I'm not very familiar with this card, but I'm guessing that cap is supposed to be a bypass capacitor for an IC (based off the fact that there aren't any bypass caps on the top side, and this one looks like it's connecting two power traces, as a bypass cap would). In that case, it should probably be replaced with a 0.01uF ceramic.

Thank you @AwkwardPotato That is the best guess so far.
