Hi,
I just got a CTK 1000 Keyboard, working fine, except the left speaker (using Headphones, the same, so left channel). When starting to use the volume fader, I hear a little crackle on the left speaker. That’s it.
I disassembled the keyboard, took out the fader, cleaned it with isoprop., but no effect, just less crackle than before. Before cleaning, there was a volume fader position, right in the beginning of it, when I had sound on the both speakers, unfortunately with a very low volume.
Maybe someone has an idea what it could be, any help is very welcome!
Thank you 🙏🏽
