Hum and noise from phono channel of DJM600

Hello. I have a DJM600 mixer hooked up to some KRK rokits that is giving a hum through phono 1 and a hissing through phono 3.

I unhooked everything from the mixer (scratchlive and two decks) but the noise keeps going. I also cycled several wires includin RCAs and XLRs and the noise was still there. So its obviously a mixer issue.

Phono 2 and all the line channels are fine and totally quiet. Any ideas on why just these two channels would have noise (and totally different types of noise)

I'll pursue this with my local repair guy and post what I find out here to help anybody with a similar problem. But any ideas in the mean time would be appreciated.

@Adam > I was going to direct you to a local service shop -- if it tests fine on CH2 then it's possible the CH3 phono pre-amp is having problems.  If the line input on CH3 is working fine then that certainly narrows it down.  If the CH3 line input is also noisy, then it could be the channel fader.
