Disc frequently making popping sound. Should I be bothered and what's the answer?
Yes - they should be silent. Suggests something like a capacitor is failing.
Keep an eye on it - if you see any sign of smoke or smell anything untoward then turn it off immediately and contact BT. Personally I wouldn’t leave it switched on overnight but maybe I’m over cautious.
Many thanks...on the case!
@Colin_LondonPersonally I'd contact BT to have it replaced now (if I had one).
