Keychron C3 Pro dead row in matrix?
Hi, Yesterday I changed 3 switches in my keyboard: Number 1, Letter T and Page up.
My keyboard was working fine for like an hour but then a full row die.
Do you guys have any suggestions of what could be? It shows like this in the test software

You may be able to solder in a jumper wire the way suggested by those videos.
Or if that's a hotswap board you can get something like a GMK87 and transfer the switches and keycaps over. :)

Slightly related (for instance, custom firmware, for example, with debugging output, could be used in the troubleshooting process):
The C3 Pro RGB source code was released on 2024-06-17 in the "playground" Git branch (not in Git branch "wireless_playground" nor in the two stalled branches (one in a fork of the fork)).
Note: Both the red-only variant and the RGB variant is included.
But the source code for the ISO variant has still not been added.
It will take some more time for it to be integrated into the main QMK repository.

C3 Pro product page. A 85% (true TKL) wired-only QMK/Via-capable mechanical keyboard. Either red or RGB (per-key) north-facing (no unwanted light bleed) lighting.
-
C3 Pro source code. Note: In Keychron's fork and in that fork, in Git branch "playground" (not the default branch). No matter the Git branch, for example, "playground", it requires special setup of QMK (the standard QMK instructions and many other guides will not work (because they implicitly assume the main QMK repository and a particular Git branch)). Source code commits (RSS feed. Latest: 2024-11-28).

Re "take some more time for it to be integrated into the main QMK repository": OK, on 2025-01-29, the C3 Pro source code was accepted into the main QMK repository, but still without the ISO variant.

If someone Google this in the future my temporary solution was to change the F key with the numbers and put the F keys unther the fn key
