sound problem

whats up you all, im having a problem im only getting sound out of the left side of my speakers on my mpc i tried restarting the unit several times and no luck, the sound is only comming out of the left side when im in sample mode or i guess any other time

i checked to make sure its in stereo and everything even when i plug my headphones in the mpc i still have the same problem

has anyone had this problem before, or know what to do
or should i re install my OS im using the free JJ OS thanks alot

well since noone else wanted to help, i dont know what the problem was but its working fine now,, i knew it wasnt wires cuz i just got new ones so umm i dont know why it did that but it was the only time and it hasnt done it since unless i was dreaming it happened, anyways thanks for everyones lack of help i think ill smoke another blunt and listen to Revolution 9 backwards <<< wow creepy you all should check it since its the whole car accident scene where paul mccartney dies <<< chronic
