This is a the Legacy Powered B unit with sounds from 2017 (6-85189). The powered motors work perfectly fine, but the sound just comes out as static.
Here is what I have done so far.
- Replaced the speaker - same issue
- Reseated most of the cables
- Checked the POT and sprayed it with contact cleaner
- Checked for loose or broken cables
I'm going to replace the 3 pin molex connector for the speaker, but it doesn't look damaged at all. Besides that could this just be a bad soundboard?
