So I wanted a small MIDI keyboard (25 key). I found a decent Axiom 25 on Craigslist and bought it (wanted something older with 5 pin DIN MIDI out not just USB). It was in really great shape and works fine (I can’t say the same about my musical abilities).
So a few days later I see another Axiom 25 on Craigslist but for really cheap (almost free) cuz the keys don’t work… Figured at worst it would be spare parts.
Got it home and yes the keys mostly did not work. Pulled it apart and while it seemed to have been worked on there was evidence of some liquid spill of something mebbe a bit corrosive. Did some troubleshooting and eventually found that the traces in various locations on the keyboard PCB seem to have corroded away. In some cases it is kinda visible while in others not so much.
So I plan to try fixing up the various broken traces and see what happens.
One interesting side note is in brightening the keys, they found that beauty shops sell hydrogen peroxide gel, called Wella Cream, premixed and relatively inexpensive. The wrap in cellophane and put them in the sun process worked very well.
