Are you hearing the hiss in the mains? Aux sends?
Does it continue when the channel is muted?
Gate control?
Any insert assigned?
Digital trim level?

When you pafl the channel, can you determine where the hiss starts in the chain?
With the channel selected, as you select the individual ‘sel’ buttons (ie, pre-amp, gate, eq, compressor) for the different areas, if you hold the ‘sel’ button you can listen at that point in the audio chain.

Are all the affected channels on the same input card? possible defective card.

Our setup is with an IDR-48, and we can have an occasional hiss, and more often than not it’s when a channel is padded with high gain.
