Help troubleshooting F-122 keypress not registered
Posted: 16 Sep 2018, 18:34
Hi all!
I wrote couple days ago about my recently found F-122.
Today I was able to connect it with Soarer's converter to a pc, to discover that half a dozen keys are dead:
S,D,4, and a couple other keypresses aren't registered.
The same keys, when pressed, have a different feel/sound as well: they feel "linear", and in fact there is no click at the end.
After disassembling the plates, a first observation of the PCB doesn't reveal any obvious damage:
some spots are brighter, less opaque than the rest, but I assume it is caused by the contact with the foam mat.
All springs and hammers are in good shape (see attached photos).
Any ideas about possible causes?
Thanks in advance
