Denon AV Receiver - static through speaker

[Wildfire]

I’ve got a 2018 Denon 4k receiver that has been solid since I got it but in the last week it has started giving a little static through most of the speakers.

Over the last week it has gotten worse to the point where the static is pretty much all the time as of last night.

All it’s used for is the ARC channel direct from the TV.

Nothing has changed. I don’t think it is heat related as I’ve turned it off and left it and the static comes in straight away.

I’ve checked all the cabling and it is all fine.

Any ideas?

Try playing a different input, CD or FM say, and see if there is an issue with the sound from those sources, it might show whether it's a problem with the Denon or with your TV source.
