Does it matter? All im asking is for the best place to buy. Im not going to throw a 2k laptop away whether it was brought 2 years ago or 6 years ago.
if it cost 2K 6 years ago I'd throw it away as it would be junk!
And the money would be better spent on a new laptop, but look at it like this, if it cost 2K last week and the screen is only £165 to buy, yeah just but it and fit it, whats the fuss? Obviously money isn't a problem!
I doubt Sony would sell you just the screen on the side, but contact them for either an in warranty or out of warranty repair, they'll charge you for the screen +fitting but then will come with a bit of a warranty hopefully!
