Hey folks,
Bit of a conundrum here, hoping you can help me troubleshoot this one.
Tested the PCB, all working. Soldered and the RGB LEDs come on just fine. After a while, the RGB LEDs turn off, though the keyboard is still working and PC still on.
Unplug and plug it back in, and only the first RGB LED comes on. The first led remains bright white despite any RGB settings. Checking it out and comparing against my spare PCB, I can confirm that it isn't working properly (spare is working fine). The solder job is clean, so I was surprised the LEDs didn't power on.
My question is whether this is likely a trace issue, processor issue, or a faulty LED.
Given that nothing I do with the RGB settings affects the display of the LEDs, I am inclined to think that the control signal isn't arriving at the LEDs.
Anyone have any insight?
Cheers!
