Probably normal. The light gating elements have only so much contrast capability and cannot attenuate the light totally.

Why will my mitsubishi lvp x300 projector only project a blue screen when I turn it on?


Blue is probably the default "no signal" screen. It means that the projector is getting no signal.

Failure to get a trully blank or black screen


Have never worked on a panasonic projector before I admit, but you get that effect when the 3 LCD panels inside a Sharp (and I assume all brands) LCD are misalligned. To get total black (LCD Projectors find this rather difficult due to the technology) the red , blue and green lcd pixels must be precisely allignend ( they are adjustable by technician and it's a fiddly job) I reckon the green panel is a touch out and it's peeking out between the red and blue squares.

Blue haze in top right of screen from NEC mt1075 projector


the light filter on the blue lcd panel is fried due to excessive dust and heat. clean out the projector with canned air. unfortunately, you cannot buy individual parts of the optical engine- you'll have to replace the whole thing. or live with it.

Large dot in the middle of the projected display


there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

Projector lamp shows blue on white screen


the red is cutting out. white=blue+green+red. without red, you get blu+green, or cyan. if this was an lcd projector, i'd say it's a burnt light filter, the red lcd, or the lcd has come unplugged. but since this is a dlp projector, you have either a dmd board issue or a main board issue. either way, it'll be pricey.

This sounds like an issue with the optical block assembly. Sony had a problem with this part in a lot of the KF-series television.

They extended the warranty of optical blocks in the KF-42WE620, which doesn't help you but from what your saying this sounds like the issue.
