I wonder if anyone can help me with some advice. I have a Sanyo PLV-30 LCD projector which I find excellent and is ideal in the small space I have for my home cinema. A few days ago I noticed what I thought to be a dead pixel appear on the projected image. It appears as a small, about seven centimetres across,out of focus circle on the top left of the screen. The image is projected on a 16:9 six foot screen. The screen is ok. When I put the image out of focus the small blemish comes into focus. Does this mean it is on the back of the lens? The front of the lens is clean. It is only noticable on a black screen. I was just wondering what it was.Is it dust? Is it a dead pixel? What does a dead pixel or dust actually look like when projected? Sorry of all the questions. Happy New Year.
