Question Rk68: LED Fails to Function Post Cleaning
I've been using the rk68 for five months now, and recently it began double-clicking. The frequency became too high, so I decided to clean it thoroughly. I wasn't surprised—it was dirty, so I removed all the keycaps, switches, took off the PCB from the plate, and cleaned everything carefully. I used a makeup brush on the PCB and a microfiber cloth with alcohol for the plate and case. After reassembly, I only checked the switches to see if anything was broken. The backspace, backslash, enter, and left arrow keys stopped working; instead, four LEDs in the same area were affected, but the key still registered. I can't remember what went wrong because the battery and USB plugs are on the opposite side. I disassembled it again without finding any issues, and now all the keys work properly (no double-clicking), though the four LEDs still don't respond. I also tried a factory reset, but it didn't help. Any suggestions on how to fix this or what I might have done incorrectly?
Before cleaning, did you have a chance to test the keyboard on another functioning computer? Or would you consider downloading the manufacturer's drivers, reinstalling them, and adjusting settings? These steps might no longer be necessary but could still be useful.
It’s probable something failed during the cleaning process. It may have simply been deteriorating, and the brushing or rubbing added the usual "final touch."
Numerous products aren’t designed for repair, and cleaning recommendations are often quite simple—any deviation from these could void the warranty.
If you still enjoy the keyboard and can operate without the four failed LEDs, it’s best to proceed as is.
Should the issues persist or worsen, you might attempt an RMA and verify the warranty terms.
