Greetings,
I've been fighting with this keyboard for weeks and as a last resort I'll try to dive into the beast "guts", with your help I hope. I wouldn't try to repair it if it wasn't because it costed me +200€.
The issue is that not one of the 7 different PCs I tried recognize the keyboard. Always an ERROR 43 code is shown. Keyboard LEDs turn on, but it doesn't work. I've already done everything I can "software side". No drivers, different drivers, specific software from the manufacturer. Same result. The manufacturer, ROCCAT, has an utility for flashing firmware but is doesn't even show the keyboard when I try to use it.
So... now I'm here.
Would anyone know where to go from here? I see various SMD, like the ARM processor, the CMOS and 3 others that when I search for the code number, nothing is shown. Swapping the CMOS is doable (with my low level of soldering skills) and cheap (around 2€). But I'm "alone in the dark" since I don't know if the CMOS is the issue or how to test it.
I know wiring is ok, connectors too (USB and the inner ones) because I did a continuity test with a multimeter.
Pictures show the "innards".
Thanks in advance to anyone willing to help.
Have a good day!
