Right. Well I'm now thinking whether it would be worth refunding the item. I bought it from Scan and of course I looked at the reviews before buying it.

They all seem to be relatively positive and I just can't really see anything negative about it. Like I said, it's seems to be fully functioning now at its best so I'm thinking that it must have something to do with the power circuits.
