For the headphone jack:
Pull it in and out several times and listen for any crackling or hard panning.
Also, be sure to listen through headphones for at least several minutes because sometimes the ‘headphone issue’ doesn’t present immediately
If you can, bring a can of compressed air…check all trig button in all trig modes and check for issues (not immediately responding to trig) or sticky buttons. If you find a wonky button, blow it out and see if that corrects it.
Do the same with the crossfader. You can check the crossfader value by looking at the display.
I have had headphone, button, and crossfader issues.
For the headphone problem there is no permanent solution other than sending it in for repair.
My button and crossfader issues were resolved with compressed air.
Good luck!!!
Hope you score a good one!
edit:
Oh yeah…be sure to remove the CF card and make sure there are no pins bent or broken off…there have been some issues with this as well.
