Question about Hitachi CP-X251 LCD Projector

1 Answer

Projection has yellow tint

One of our teachers has the Hitachi CP-X251 and from the computer the image is fine. From the projector, it has a yellow tint. The color/tint option is not available to me. I have adjusted the picture (red, blue, green), and nothing fixes it. Does this indicate a new bulb is needed?

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.

Hitachi projector cp-s318 and the pictures give off a red tint.


Hi,

Make sure the Computer Input is set to VGA, Computer, or RGB (depending on which projector model you have). Go through the menu settings of your projector.

Hope this helps

The image from my cp x251 is uneven the top and right side are angled but the bottom and left side are straight and perfect on the screen.


this is a common problem with projection systems this is the reason that most screens are lined with black felt its non-reflective and works great to hide uneven edges also try balancing out the difference with the keystone adjustment

Hitachi cp-x251 lcd projector cannot adjust the tint.


reset the settings to factory default. make sure that if you are using the computer that you are on vga, not composite. if it doesn't get any better, check the lamp for bulges, black spots, or fogging; replace if necessary. if all that is ok, you may have fried polarizer filters on one or more of the lcd panels due to excessive dust and heat. if that is the case, you'll need to replace the entire optical engine.

Image has yellow tint even with nothing connected


I am not a 100% sure, but that would be my first thought on what the problem is. I would call Hitachi support and go through troubleshooting with them to find out the cost of the repair.
