Reply to DJM 800 Issue

I just bought this DJM800 off eBay for a good deal! It hasn't given me any problems until today when all my sound outputting to my XLR cables went haywire. It basically stopped outputting and all the gain lights on every channel on the mixer lit up all the way to red. It's a little frustrating when you're in the groove and it totally kills the buzz.

I usually keep the gain at a relative medium a happy green and sometimes yellow, I was using a Technic 1200 M3d for my left deck on channel 2 and my trusty CDJ 900 for my right deck on channel 3. It happens kind of randomly. Sometimes right away, sometimes five minutes in.

Any help or ideas would be greatly appreciated!!
