Hello, I have a problem with my keyboard. I have a Logitech G413 Carbon. I bought the keyboard damaged for repair purposes. The seller talked about the bottom line of keys (from left CTRL to arrow keys) getting stuck, double-clicks appearing and the buttons not working every time. after purchasing the keyboard and connecting it to my computer, testing it in several programs and playing a few games, there were no problems, the keyboard worked without any problems. I used it for a few months without any problems, but recently I had this problem. the bottom line of buttons started failing a few months after purchase. I don’t know how it’s possible and what the problem is. Could it be a problem with the keyboard driver (not a software driver, but a physical driver inside the keyboard that controls the voltages)? or the keyboard was flooded and there were some short circuits? I find it hard to believe that only the switches on the bottom line of buttons failed.
