Annoying buzzing sound from Microlab FC330 subwoofer - not sure whether to replace ?

Hello

I have these connected to my LGOLED55B6 TV.

Recently I noticed a really annoying buzzing sound coming from the subwoofer.

This persists with different sound sources & disconnected. The only thing that cures it is turning the unit off.

I connected a ground loop isolater between the TV audio out & FC330 input but made no difference.

It's a real shame because otherwise the sound is perfect for our requirements.

I have an identical unit at work connected to my PC, and do not get this issue.

Obviously I don't want to purchase a replacement if the same problem occurs.

Advice gratefully received.

Thanks
