I've finally received my 2nd warranty replacement for the recent issue.
Lets just say that LetMeRepair UK who are Asus's UK repair agents are still upto their old tricks, the first thing i noticed when the courier delivered the box is that it wasn't a brand new sealed unit direct from Asus, after the previous experience of a refurb from them i wasn't full of confidence with what i was about to receive.
Anyway i opened the box, at first glance it wasn't as bad as the other one that i received from them, let's face it nothing could be that bad, their was obvious signs of use though with minor marks on the plastic and on the base. I started to put it together, this is where i couldn't go any further. The idiots at LetMeRepair had forgot to put the bolt in the box that secures the base stand to the column on the back of the monitor, not only had they forgot to put that in they also forgot to put in the cable management bracket/clip that clips onto the back of the support column.
Anyway, i rummaged through the tool box and found a small bolt that was the same thread size. I connected everything up and switched it on, at the top left of the screen their is a small area of dead black pixels, it's only small maybe a couple of pixels, on a white background it looks like their is a bit of dust behind the screen.
Not perfect really considering this is supposed to be a fully checked warranty replacement along with the fact that Asus tell you that their warranty is a Premium 3 year panel guarantee.
