lights are on but no sound on any output

Been playing the JM4 for a couple of months now with no troubles

yesterday i went to a gig and when i plugged it in i got most of the lights  except the light in the rectangular screen that tells you what preset you are using etc.

I get no sound whatsoever from the out to amp, the stereo out or the headphones out.

the unit was not dropped or otherwise mistreated.

any ideas what this might be causing this behavior?

RE: lights are on but no sound on any output

I would recommend performing a factory reset on the JM4 by holding the 'TONE/SETTINGS' button on the JM4 as you power it on by plugging in the power cable.  Keep in mind this will erase any saved settings and presets, but your recordings will still be intact.  If the problem persists, you may want to try re-installing the flash memory on the JM4 using the procedure on the following document:

  If the problem persists, you will need to take it to an authorized service center:
