Analogue noise on input 8

Today,my input 8 started producing static noise from out of nowhere. It started with a little ripple and then increased to a static white noise that every now and then changes color a bit. The noise doesn’t respond to the padding or analogue input knob, but will mute and change volume via the MR editor. Noise level is about -32dB when I monitor it in LogicProX…

When I engage and disengage 48V it’s switched off temporarily. But returns after a few seconds (I assume that’s just a muting circuit working to prevent pops from switching 48V)

Anyone any idea what’s happening here? And if there’s some way to repair this?
