The diodes are all fine. (Yes I thought they were FETs, when it said Dxxx on the silk screen, doh!)

I gave up and bought a 460CDT with a broken keyboard and missing HDD. The keyboard from the 220 should fit...

Hopefully someone will kick this thread with a solution in the future and solve this mystery.

Without schematics I doubt. I've been on my 200 for a year now and after trying it all I'm left with using a thermal camera to spot anything.
Many components I suspect are simply impossible to find. Even if I can find the issue if it is those I'm done.

Old stuff, what can you do?

Where I live it's already the best option to stay home and nerd. 😀

Good luck finding a new one!
