I may have initially posted my original posting to the wrong category. Posting in this area for greater visibility.
Unit purchased new years ago for piano lessons. Worked for a few years then issue with no sound occurred. Lessons ended and piano remained in same spot until now, when I decided to “tinker”. Several forums zeroed in on issue with Amp board capacitors as being the likely issue. Recently purchased new Amp board from Syntaur and just installed. Initially, issue remained; however, when reconnecting the ribbon cable from AM to DM, sound was produced on one speaker. I checked the seating of the cable on both ends, then tried again, but returned to no sound condition.
Since this is a friction connection on both ends and the the cable run is short, the tension on the connections has loosened and does not appear to seat fully, so I am thinking that this may be the culprit.The leads on both ends do not appear to be damaged.
I have very basic technical knowledge in this area and do not want to sink more dollars in this unit than it is worth… but it is a decent unit that I would like to keep if at all possible.
Any guidance or assistance would be greatly appreciated. Thank you in advance.
