History: the above arrived from Hong Kong, worked for 30 minutes or so, died. Swapped all around, nothing, smelled magic smoke. Bugger.
Emailed seller... emailed seller... emailed seller... started Paypal claim and seller immediately wakes up and rolls out the usual guff about USB ports and stuff. Told him it's definitely broken and could I have a new one please? Apologises and asks me to post it to him for inspection. Fairy nuff.
Just been to earth the coax, as suggested previously, and saw pretty little blue sparks when making the final connection from the coax to the pc's case! Oops. Looks like my naughty coax/aerial booster might have killed the tv stick. Surely it must be a bit s**te though, if that's all it took? My meter couldn't pick up any voltage on the coax so there's not very much there.
Does coax usually spark? I've never looked.
