Sizzling sound from inside the Wiim

[Amadeusz]

Hi,
I bought my Wiim Ultra a week ago and since yesterday I hear high pitched sizzling sound from inside the box. It stops when i disconnect HDMI.
I tried connecting Wiim and TV to separate power outlets, disconnecting antenna form Tv, I also tried different HDMI cable but nothing helped.
Does is sound like a faulty unit? I have no other ideas...

Sounds faulty. Literally ;-). My months-old functional Ultra has never made such noise.

Definitely sounds like you have an issue. Where did you purchase it from? If you got it from Amazon I would utilize their excellent return policy and exchange it.
