Since i have been away from the community for a while i could not help but post the latest, since having my 923 exchanged just two years ago for the 853 over a pixel issue i now find myself in the same predicament i did then!, the HX853 has started to do this and thus far one pixel has gone and in its place a lovely little red x i know i'm covered with a five year warranty but i'm very dissappointed its happening all over again so if anyone has any pointers/advice to offer then now is the time.
