Yeah, that definitely sounds like a physical problem somewhere. It is most likely the wires that are soldered between the controller PCB and sense PCB, like darkcruix said, however it could also be on the controller itself.warty wrote: ↑29 Aug 2020, 07:33My F77 came today! Yea! Some of the keys don't work... bummer.
The keys that don't respond... it's not the springs, and I don't think it's the hammers, as I can see that they move up/down with the springs.
I tried to run ibm_capsense_usb_util.app v0.9.0 (latest on the xwhatsit site). I'm familiar with this program because it's what I use in my beam spring. But it just freezes if I select either of the 2 devices (that aren't the beam spring). Disconnecting the beam spring didn't help either.
I PM'ed for an invite to the QMK beta. There's probably nothing I can do in the meantime?
dead keys: z, (but not x), c, v, b, n, m, ",", . , right shift , keypad '.' (for me; so row 4, col 3); every key on the bottom row, including spacebar.
Looks like two of the rows are dead, I have highlighted all of the traces on the controller PCB related to those two rows. Since they are next to eachother I think it's most likely that they are shorted together somewhere.
Please see the attachments, and inspect those areas, and the attached wires visually. (If you have a multimeter, you might even try to beep it out to see if they are shorted)
There's a chance though, especially if it's the wires, that once you open up the keyboard the short goes away, just because you moved the wires a little.
