    My kids sprayed glass cleaner on our Samsung 720p DLP after I owned it for 3 whole months which caused a big black spot on the screen. Best we could do (without replacing the screen) was to take a hair drier and put it on low temp and dry it for quite some time. That made the black spot turn grayish and the drier did put a light indention in the screen but it came out better than the original black spot. Now that I have replaced that TV with a new 1080p LCD, the kids who caused the problem are watching that TV.

    Hello every one
    It’s maybe because of optics that is covered with the spray. there are several videos in youtube for cleaning optics. you can use them or just let technicians and professionals to do it for you.
