Another friend had 3 "Dead pixels" on his Gateway (old 19") CRT as well. Anybody know how this happens? personally, i have never had this problem on a CRT...
I've never seen this in a CRT monitor (I have seen discolorations, etc., but not 'dead' areas). The only thing I can think of is that the shadow mask/aperture grille was somehow damaged -- damage to the electron guns would affect the whole display, not just one section, and phospor wear is generally much more even than that. Were these displays shipped without being carefully packed, or dropped, or anything like that?
