Sound only from one side of phones

hey guys, just upgraded to the 5000.
i was making a beat, and all i have is the mpc and my headphones, i restarted it and now
i only get sound from the left side, i checked the mixer panning but i dont know where else to look
i searched this and couldnt find anything about it, the headphones work on my laptop.
cant check the stereo out, not in the studio for the next 2 weeks.

maybe your headphone plug is broken.
try some other headphones

thank god i'm not the only one this happened to.

yes, ... it happened to me about 6 months ago, ... and i was in a total hardware setup running everything through my mpc 5k, .... well, ... now i have to use a sound card, (originally firebox, ... but now i have a focusrite pro24 dsp), ... regardless, ... once you only get it coming from one side of your headphones, ... there's nothing you can do, ... i even tried to look up parts online and could find absolutely nothing, ... what a shame.

i love my 5k though, ... and i hate everyone who doesn't like, ... and yes, i said that shallow on purpose because i am totally shallow like that.

Just wiggle it........................just a little bit.
