Here's how my RMA went - spoke to Philips by phone and they asked for photos of the monitor and a PDF of the invoice to be sent to them(made them confirm they'd send out a new, not refurbed, monitor). Did that and think about a week later Repairtech phoned me to arrange pickup, picked up(DPD courier) on a Wednesday. Then heard nothing when surprisingly there was a knock at the door the following Monday and a guy(TNT courier) delivered a new monitor, tracking label said it was sent from Rotterdam.
So for me there was a gap of a few days in the monitor swap, however don't get too disheartened because once you get a working monitor you will definitely be happy you stuck with it.
Shame Philips have such **** quality control, all the defects I experienced could only have been missed if the quality control staff were literally blind. I'm not just talking about the odd dead pixel but large physical defects, awful quality control.
