Hey everyone, I created an account just to make this post and hopefully receive some help. I have an RGB Pok3r which is about 4 years old at this point. It's served me extremely well so far.
Recently, it's been having this issue where a few keys in the second last row randomly turn on and light up blue. They are always the same keys; LShift, x, c, v, b, n, and m.
I always keep the backlight off (it's kind of distracting for me), so it's very noticeable when this occurs. To fix it, I have to turn the backlight on (Pn + 5), then turn it back off (Pn + 4). Once off, it usually turns back on within a few minutes. I find myself doing this process several times a day, and it's becoming very irritating now.
In the past, I have opened up the board to insert a layer of microfibre cloth between the PCB and the metal case to try and dampen the sound while typing. So I thought that due to the microfibre material touching the PCB, it might be bridging some connections or something and causing this issue. I took apart the board again and connected it while it was out of the case, and the issue persisted. I even separated the two boards (this keeb has 2 pcb's sandwiched together, one for the backlight, and one on which the switches are mounted), and powered the backlight PCB, and the blue LED's lit up again.
I've reset the layers several times using the instructions on the manual, but the lights are still there. Those keys are definitely not programmed by me to be switched on.
I am not discounting the possibility that I accidentally knocked off a small PCB component while opening it up in the past.
What can this be?
