PO-20 No Sound

My PO-20 built in speaker isn’t working. Any suggestions why or how to fix it?

Sound does work from output jack.

Might be a connection problem in the output jack. Normally, if nothing is inserted, there’s a bypass switch which makes the audio connection to the speaker. I suggest cleaning the contacts in the output jack. Or try repeated plugging and unplugging…

Thanks for the tips. I will try cleaning it out and see it resolves my issue.
