I have seen a few threads and FAQ,s where people have mentioned LCD panel warp etc. I also gather that DLP components last longer. My questions are: Has anyone ever worn out a projector and is there a rule of thumb as to a pj's life span in hours. Typically used in a clean, permanently mounted situation. I realise of course there are many variables but am I going to buy something that lasts for say 5000 hours, only to find out its time to think about replacing it again. Thanks again for all your help. Chipster.
