I have Surface 3 which was pucrhased directly from Microsoft in Feb 2016, so warranty expired Feb 2017.
Just after the warranty expired, the screen started to develop a significant problem - see the attached pictures (I guess it may have started developing during warranty period but unfortunately I did not notice it until it became really bad).
Basically, there are several horizontal wavy lines visible on dark background; on magnification (sorry for fuzzy picture) you can see that these are made of massive amount of hot pixels (red, green and blue). The Surface has not been abused, nothing was spilled on it, it was not dropped, always carried in a protective pouch and basically used normally.
Obviously it is not something that is expected to develop on any device just after a year, so as far as I am concerned it can only be due to either unsatisfactory quality or a manufacturing defect. I contacted Microsoft support and sent the pictures but the support guy dismissed this stating that these are dead pixels (? obviously not) and "If it would have been a manufacturing defect, you would have reported this problem long ago." Obviously I could not report it as the defect was not apparent until just after the warranty period. This does not change the fact that this is highly abnormal, and you would expect a reputable manufacturer to try to address the issue. The only "solution" offered was out of warranty replacement, the cost of which is basically the same as buying a new tablet, after 1 year of usage !
Have you ever seen anything like this, and how can it be sorted ?
