Does it matter? It's not been out for a year yet, so there's no way it's out of warranty. I get this might require a bit of a fight but if it were me I'd go for it.
like a tit though... i cannot find the receipt...
To be fair unless it's obviously damaged Sony should sort it for free anyway, given that you cannot possibly have owned it for more than the 1 year standard warranty
@Neodog Are you in the UK? Who did you buy it from? Take it back there. It is still under warranty.
