The charity I help has a 28month old Acer P1303W projector which now projects white dots onto the screen. Anywhere where we commonly projected black (such as the boundaries around the outside of the welcome screen) now has many white dots. Its as if the projector remembers areas which often project black and something has burnt out and now projects a white pixel.
I believe this is the DMD chip which is an expensive component deep inside the projector - probably not a DIY replacement, even if I can buy the part.
I have read that in some parts of the world the DMD chip has a 5 year warranty
Acer has listened and didnt argue when I reminded them of the 5 year DMD chip warranty and issued a reference number so that UPS will collect the projector and send it in to them for repair - Does anybody have experience of Acer's UK treatment of warranty claims on DMD chips?
