Yamaha PSR-11 Speaker malfunction

I have a Yamaha PSR-11 that I bought when I was a teen (about 25 years ago) that is having a problem with the speaker. My daughter uses it now so she can have a full-size keyboard in her room instead of using the piano in the common area.

Anyway, recently, the speaker decided to quit after a few minutes or less of use. I have found that the headphone jack still functions so it can be plugged into an outside amp but wanted to get the internal speaker back up and running if possible.

I took the unit apart and noticed a board with a couple of capacitors on it between the actual speaker and the unit itself inside. My assumption is that one of these capacitors are bad and that is causing the sudden failure of the speaker to get the signal that is being sent to it.

I just wondered if anyone had any advice or info on where to acquire a new internal board or capacitor to fix the speaker. Perhaps this is a common problem that someone else had that can share the info. Any helpful info would be appreciated.

Otherwise, I will just use the external speaker option.

Thanks!
