Right my SP3 is on the way back to MS over a 6 inch scratch on the screen from factory. Now i've been skimming the internet for how many people have had scratches, I then stumbled across an article on dead pixels, scratches, and of course this yellow banding, then i heard about chassis separation. I ask what to look for as when my new one arrives I'm going to check it over before I start installing my applications (I wasted a long time on that last time) I just want to know what people have seen as a common fault. I have OCD so anything is going to drive me nuts once I've found it so doing some QC before setting up seems a prudent action. So what has been noticed? if any one has pictures of these faults, I'd be most grateful if you could upload them. In hindsight my unit had a scratch which a tempered glass screen protector could have solved, bearing in mind the rest of it was bang on. any-ways please let me know, this will at least give me something to look through while i wait for my new unit. Thanks, Luke.
