Question about Audio Players & Recorders
There are 8 keys in sequence that sound only once when my Casio keyboard is powered up, then they won't sound again until the unit is powered down and then powered back up. When it is powered up again, the same keys become inoperative after they are struck once. I have two WK-3000s that developed the same problem about 30 days apart. The second keyboard's malfunctioning keys are at a different octave than keyboard #1 above.
Just wanted to "chime" in. I just recieved a Casio keyboard from a customer with this same problem to work on. I initially found 4 corroded solder joints. Repaired them, same problem. Ginocumbe's description leans me towards capacitors. Will let you know what I find or even if I cant figure it out. Though 2 years ago, you probably added your synth to the land fill.
