Hey, My Rapid-I is 4 years old and over this time period, the LEDs started burning out one by one. Since my product was past its warranty and no service centres near my location, I decided to resolder the LEDs with new ones. The replaced LEDs work (albeit being of slightly different colour temperature, but its no issue for me), however the Esc, F1-F12 keys and the Prt Scr keys aren't working now (even though the LEDs didn't work, the keys themselves worked without any issues). I've checked if any tracers or the board is damaged but the board and tracers seems to be fine. Is there any way you can assist me with this?
