Juno 106 no sound from any output

Hi and thank you for any information that this forum is able to give. My juno 106 has been working just fine. Of course I've had a few chip replacements along the way. It was on earlier today working as it should. I returned to it after it was on for a little while and that's when I noticed there is no sound. I tried the headphones as well. Same. I don't get the chorus wave sound as well. Nothing. just a pop/click when I turn it on/off.

If you don't even hear the background chorus noise, then I'd say it's a good chance it's lost the final output stage.  Not exactly a user-serviceable thing to fix, though.  I recommend you find a reputable keyboard tech and have them take a look at it.
