Hello everyone,
after connecting my beloved Realforce R2 to a faulty USB hub some months ago it completely stopped working (USB not recognized at all).
After inspecting the PCB the only thing I was able to notice was the status of the ICs labeled "14G1" or "1491", it does seems to me that all 3 of them are in pretty bad shape especially in the top-left corner + I could smell a distinctive smell of something burnt (see photo attached).
Is there anything I can try to verify what's the actual problem? I'm not an expert in PCB troubleshooting but I can surely use a multi-meter/soldering iron if pointed in the right direction.
Thanks in advance for the help, as you all know this keyboard is pretty expensive so it would be a pity to just have it sitting somewhere taking dust...
EDIT - this is how a clean board looks like:
