So my father has had this projector for about 4 years now and we have had no problems with it. About a week ago a problem with the blue light has started. For some reason the blue light wont align properly, thus making the picture have a blue "ghost image" to the right of everything. We have tried to realign it via the settings but for some reason the blue lines will not move correctly to align with the other lines. What could be the problem? Any help would be appreciated. If you need a better explanation please let me know, we would really like to figure this out.
