Question about NEC VT470 Multimedia Projector
Hi guys - I need your assistance, I am trying to work on one of these projectors for a business. The office manager claims that their staff replaced the bulb already and doesn't know if they cleaned the filter. The display shows fine except some blochy areas on the screen, I don't know how to describe it. It's looks like over saturated with color in these blochy areas of the display. This projector probably runs 9 hours a day for 5 days a week, minimum. I cleaned the outside lens, but when I look inside the lens when it's on, I see dots or something inside it. Does it need maintenance and cleaning inside the unit where the light is coming from? Let me know what the Gurus think, I appreciate your wisdom.
