HItachi cp x1250 blue tint area on black background
HI, I have a HItachi cp x1250 video projector wth a blue tint area on about 1/3 of the black background. the area is irregular in shape but is centered in the top left corner and fades to black toward the other 3 corners. this is visable clearly with a solid black image. but it also effects full color images. Pure white images are white with no problem visable. this shows up with either the RGBHV input or composite video inputs.
please let me know if it is adjustable or if it needs serious repair and the ballpark cost of such. thanks, Dave

hi, Go to menu and then select main. then select reset and execute it.After that try to adjust the brightness and contrast. Remember on thing, in some projectors the brightens and contrast will be active when there is video signal. also try that. ok
This could also be a setting. If you are using component video as a connection, make sure that the unit is set for RGB if coming from a laptop or other computer system. If the projector is set to YPrPb, the picture will look purple or bluish as you describe. Change the setting to RGB and all should be well.
From your description, it sounds like a problem with the blue color. Green LCD=purple onscreen, Red=cyan(baby blue) onscreen, Blue LCD=yellow onscreen. It could be a lot of dust on the blue lcd panel, or worse, might be a burned polarizer filter behind the lcd panel due to excessive heat. If you can focus on the yellow and its tons of yellow specs, its dust. A burned filter however, must be replaced. A technician trained in projectors will have to do it. The filter material is glued to a thin glass panel and is replaced as a single filter. It's a very involved repair.
