Reply to CDJ1000MK3 Pitch fader repair

Hello,

One of my CDJ's is having a little problem, the pitch is skipping from +1,5% to somewhere around +2,5-3,0%.

Could someone maybe tell me if it is possible and how hard it is to repair/replace the pitch fader on a CDJ1000MK3?

A ''how to'' would be great, couldn't find one myself.

Thanks in advance
