Question about Hitachi CP-X430 Multimedia Projector

Open Question

Hitachi CP-X430. Image turns purple after a while.

We have two of these projectors, same model-same problem.  The image from the projector turns purple after a while, and it happens on all inputs.  Turning the power off, then back on, solves the issue most of the time, albeit temporarily.  Perhaps some component in this model has exceeded it's lifespan?  I'm curious to know if anyone else is having this problem as well.

    the top right hand corner is doing the same on one of mine as well. I dont know either. But i like to take the bulb out and blow the unit out with a can of air and wipe what I can then do the same to the other and switch bulbs and rotate the units because I have only one bulb and 2 units as well. there is also a place called RELAMPIT.com that will get you a new one for 250 or that they redo the bulb with a longer garanty because they use a better filament.

it sounds like the A/V reciever does not upconvert the component signal to HDMI. Not many do. The Marantz recievers will (SR6001, SR8001, etc..). Also bear in mind that HDMI cables are finicky and may require amplification over a few meters long.

My projector is not Hitachi but I had a similar problem. My manual suggested checking under "signal" to make sure that "auto" was "on". The thing is, there were two places where "signal" came up on the menu. I had to go under "set-up" to "signal" and then I was able to correct it by setting "auto" to "on". I hope this helps.

Hi there

In your Menu options there is a subfolder where it either reads lamp or lamp timer.

Scroll down to it and hold down you right or left arrow key on the Projector for a couple of seconds.

There is a small tab on the lamp cover that should press into an "L" shaped slot on the lamp housing. This tab may break off, and not press into slot far enough to make the lamp dectection switch click. When the lamp heats up, the plastics expand and the detection switch opens. The projector quits as if no lamp is installed. The fix is to make an extension for the tab. I cut a small piece of sheet metal and crazy-glued it to what was left of the plasic tab.

Flip image on Hitachi CP S240


The setting you are looking for is called mirror. If you go into your menu, you should be able to find it. I'm not fmailiar with that exact model, but Hitachi is very good about keeping their projectors consistent where the menu/options are concerned. Once you find the mirror section, cycle through the options (there will be 3 or 4) until you find the one you need. If your projector is hanging upside down from the ceiling, select the ceiling option.

Upside down image


These projectors are designed to be mounted upside down. Think of a projector that is ceiling mounted in a classroom. Change this setting in Menu - Advanced Menu - Setup - Mirror.

MacBook connected Hitachi CP x301 Icons do not appear


Ok what's happening is that you have it set up as an extension of your desktop, you need to mirror the displays. when your projector is plugged in and it is showing only the desktop background, open "System Preferences," click "Displays," click "Positioning" and check the box that says "Mirror Displays." This should do the trick.

Hitachi projector cp - s210


hi there,
I have just done the exact same thing today. Press menu button on projector. Scroll (navigate) to the mirror option. This give you the options to mirror image left to right or up and down.
This should fix any of your problems.
Cheers

Green backround on the image


My projector is not a Hitachi but I think the menus are similar. You might try finding "signal" under "setup" in your menu and check to see if it is on or off. You want it "on". I hope this helps.
