Repair MPC

I' m having some technical problems with my MPC that are driving me insane. The first problem is that for the first 3o mins or so that it's on I get this loud noize like the one that you get when you tune in to a channel on TV that doesn"t exist. Sometimes if I tap the front of the console the sound stops for a little while but and then it usually starts again.The other thing is that during that time I often get louder sound in one ear than the other but it contantly switches from one ear to the other. Finally, I have to reallly press on butons to get respone frm them . At first I thougt there might just be a loose conection somewhere in the MPC and that the reason it works afetr awhile is because the onections heat up and become "better". Anyways this is driiving me insane and I've been trying to find a techniian for this here in Montreal(Canada) and there aren't any aparetly. Any help would trully be appreciated.

got a turntable hooked up?

try www.mpcstuff.com for button replacement unless its all buttons in which case its time to ship it off for repair

Yeah, I have a turntable plugged in but it isn't the ttable that's making that sound.It occurs even when I'm in the play\record screen and it really is not static or whetever from the turtable.

have you checked your headphone jack? kinda obvious, but it might be the problem, if you twist it and the sound gets messed up sometimes while you twist, then it might be your headphones or the jack itself in the mpc. this happened to me when i had a creative nomad zen xtra music player thing, and i sent it in and they fixed it.
