    Mac Pro A1398 Malfunction Keys

    Hello everyone!
    I'm having some issues with my Macbook Pro Retina 15” A1398 EMC 2909 keyboard. Some keys are not working properly. Keys: D,F,G,H,J,K,L, all same row keys.
    I'm using 820-00163 schematics to track the keys, but I don't know which set of WS_KBD these keys belong to. Is there any guide for that?

          HP x360 14-CD Laptop 3 keys not working (G/H/ESC/) Help please!!

          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.

          HELP! A1398 Dead,
          by Fam787
          I bought a second hand Mid 2014 A1398 MacBook Pro when I lived in Australia. I'd bought it as a back-up machine because I had a Mid 2014 MacBook Pro, and realising it might one day fail, I wanted a backup machine because I don't like change.

          Two weeks after buying MBP2, the seller called me to check if everything was OK with the unit, which I thought was odd. At that stage I might have turned it on a couple of times, but I'd not used it when he'd called. Over the last few years I used the machine seldomly because my original mac has been pretty OK. Every 3-6 months I'd charge it...

          Can someone please remove the firmware password from this dump?
          I have tried the $SVS method but didn't succeed.

          Thank you!
