Superhub Buzzing from SuperHub while on power?

Hi Guys,

Another question, havent been on for a while.
Buzzing from SuperHub while on power.
Should phone support?

Also Tv keeps forgetting the fav list, then press back and Fav again and its back again. Happens 3 times a day apx, did it 4 times today so far.

Thanks for looking.!

I wouldn't leave it plugged in at night or when you go out.

I have the Tv box on top of a Sub speaker, would this cause the fav fault?
The Hub is about 10 inchs from sub also?

What is a "fav fault"?

It has to be noted, if i place electronics too close to my subwoofer, I can hear a very low pitched hum from it. I gather its some form of induced voltage being converted into sound.

Its also worth noting that, according to previous posts on these forums, some superhub PSU's tend to whine or buzz, and its worth calling in about it.

Most of the psus I put in have this fault

I had a dream (well actually nightmare) last night. I dreamt that my VMNG300 caught fire and I had to replace it with a Superhub.

Undocumented feature, surely.

Most modern universal (110-240v)switching supplies tend to struggle at high mains and light load. The result is usually a buzzing or high pitched singing. It does no harm and there's no danger but it can be annoying.

I design these things and when the client wants the lowest cost, and they usually do, somethings are sacrificed such as good low load behaviour.

Lowest cost...

... Superhub ...

... No surprises there.

Its not entirely harmless...

Well I was speaking from a technical point of view. I don't do phsycoanalysis.

i've had 3 superhubs each with a new PSU and they all make noise. I know how annoying it can be. But apart from getting a 3rd party PSU with the same output as the VM one, theres not much you can do.
