Over the last couple of weeks, my SKY+ box has started buzzing quite loudly. Not noticeable if you're watching anything with the volume on, but annoying if not.......... I've tried powering it off and back on, and the buzzing stops for a bit, but then comes back again. It doesn't buzz all the time though, so my guess is it might be the fan ? Is it safe enough, or am I better getting SKY to come and have a look at it ? Its got about 3 weeks left on the warranty, so if I'm gonna act, I'd better act now ! Ian.
