• Is a fluorescent light illuminated near the remote control sensor?
• Is the image position correct? (See page 36.)
• Are screen mode adjustments such as picture size made correctly? (See pages 39
and 40.)
• Adjust the picture tone. (See pages 28 to 29.)
• Is the room too bright? The picture may look dark in a room that is too bright.
