Projector does not recognize computer


Hi Becki.

Projectors will usually be identified on your computer as additional or optional screens/monitors. Depending on your setup (laptop/desktop) you may have some alt keyboard buttons with icons for single/multi screens. You will also likely have monitor control panels or non-windows equivalents. In Windows, for instance, right-clicking the desktop will usually bring up a monitor properties page. There you may be able to then select if the projector is a mirror of your desktop, an extension, projector only, or computer only.

if the computer says it sees the monitor, then you'll likely need to toggle whatever sort of menus the projector has to select the input port. Looking through the manual (
http://www.hitachi-america.us/supportingdocs/forhome/DisplayTechnologiesGroup/lcdprojectors/SupportingDocuments/cp-x251_um.pdf ) , suffice to say that there are multiple ways to connect and, with that, plenty of ways to have your cable be hooked up and ignored nonetheless.

Hoping this helps!

It says to Check the air flow


Open the cover. At some ends there will be 'filters', to clean the air entering the projector. If these filters are blocked with dust or lint, air flow will be blocked.
Clean any dust from these filters. Close the cover and check whether your problem is solved.

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.

Projection has yellow tint


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.

Need leveling mounts or legs for lcd projector


Best solution I found is going to a hardware store with your broken legs and buying a nice pair of carriage bolts with the same screw pattern. They don't break and work much better then the original legs. I stuck rubber feet to the bottom of the ones I got and am seriously considering going around and replacing the stock legs with these as a preventative measure.

Problem with hitachi cp-RS55 multimedia projector sir


There is a menu item which has both the lamp hour reset and check air flow, etc. You must go into the menu and reset the air flow item. MAKE SURE YOU CLEAN THE DUST FILTER!! Heat is the number one killer of projectors and Hitachi's run "hot". I clean my projector once a week--Hey, I'm not rich. lol! Also, excessive heat will cause the lcd panels to fail prematurely and cause lots of other components to do the same.--Rick
