Tried connecting to my A/V Receiver or Headphones - same thing.
I followed the manual and did a full factory reset. That didn't help.

What do I do? I bought M3 over M50 because it is made in Japan vs China, so I was hoping to see a good quality keyboard. I was so happy to buy it.
I don't know what to do... If anyone experienced the same and knows how to fix it, please let me know.
I would hate to ship it back to korg after using it just under a month...
