    Logitech G613 sticky keys (keys duplicating)

    Trying to fix for a friend of mine.

    Random keys (primarily L, M, A, and G) occasionally duplicate inputs (you press the key and get 2 copies of the letter instead of one)

    Googling led to a person saying the issue is the board flexes over time which makes a bad joint on the 0 Ohm resistors along the back of the board. So I opened the keyboard up and reflowed every single resistor. Every one I heated with hot air, nudged it and let surface tension pull it back in. I tested the resistors and they are all close to 0 Ohms (0.2 to 0.3 ish)

    I also swapped out the L and M key with 2 keys that were never, ever used just to eliminate any mechanical failure.

    Upon testing however, the keys still occasionally duplicate. It is working better, but still not perfect.

    Any ideas?

      Logitech keyboard switching 2 keys
      by Techboxcomputer
      This has happened on three keyboards, so now I am assuming it is something in the machine but I can't track it down. Every time you plug in a logitech wireless keyboard it will immediately switch the "c" and the "v" permanent on these boards. There is no malicious software I can find, the board cannot be reset or put back. The very last one I tried was a MK 235 with the same end result. If you plug in a Microsoft wired comfort curve board, no problem at all. I have tried cleaning the system, deleting all boards from the device manager, updating the Logi software,checking MS...

      HP x360 14-CD Laptop 3 keys not working (G/H/ESC/) Help please!!
      by TheJeanox
      The laptop suffered a liquid spill which caused the keyboard to be damaged (the liquid did not reach the motherboard).

      I bought the replacement part, when I tested it before assembling it I realized that the aforementioned keys do not work but the keyboard is fine, it was tested on another computer and indeed all the keys work.

      On pin #32 of the keyboard connector there is a voltage of 3v, when pressing the keys that do not work the voltage drops to 1.3v~1.5v but if I press any of the keys that do work the voltage does not drop, at this point I can no longer understand...

      Yamaha Tyros strange keys issue
      by daigs
      Hi, I'm a technician as hobby, I repaired several yamaha keyboards in the keyboard unit (some key doesn't sound or sound too much, etc.).

      I'm in trouble with a never seen case regarding a Yamaha tyros 2 61 keys. The problem is that all the couple the D# - A keys sound only the first time I press them. The second time I press them they don't sound anymore. The first time, they sound with a sustain too. The D# and A are on the same wires in the matrix scan as you can see from the attached schematics. I found a video in which the problem is as similar as in my case.

      Logitech R20 speakers - Replacing one of the speakers.
      by Widget
      Hi guys,

      I have a set of Logitech R20 speakers, one of the speakers wasn't working, so I took it apart & there was no continuity or Resistance when probing the Tinsel Wires. Plus looks like the speaker was exposed to liquid as there's rust on the metal speaker frame.

      Just in case, I removed the other speaker and installed it in place of the damaged speaker to make sure the PCB of the damaged speaker was ok & it seemed to work fine, so it looks like it's just the speaker for now.

      Printed on the back of the Logitech speaker is;
