One of my customers asked if I could repair a Fesley FPE160 digital piano. These sell on Amazon for about $175 Canadian. The Aux receptacle fell inside after about 2 months and now it cannot be returned. I told the customer to have it repaired is not feasible as the piano doesn’t make sound anymore and the chances that the receptacle has shorted out something on the main board is likely. Sometime you need to help the customer make the decision to abandon an economically unsure path and simply by new. Donate the old piano to someone to fix for free.
