Question about Office Equipment & Supplies

Open Question

First, it is not a printer, it is an LCD projector, Hitachi RS55. I gives a yellow screen and all images have s strong yellow cast as if there is no blue component. Changing the settings of colour makes very little difference. Internal inspection shows a blue light in one of the three parts of the projection system. Is there a light filter which might be blocking the blue beam? Apparently, the change from normal was sudden.

I work in a school and one of the projectors has a yellow area in the centre of the projection. The lamp has been replaced ?


Your Blue LCD Light valve is burned or has dust on it which blocks the blue color.

With RGB, the absense of blue (Red + Green) is yellow.

If you're lucky a simply cleaning at the light valves will solve your problem. Otherwise your looking $$ for a new LCD valve.

I have a Hitachi LCD projector model No. CP-RX70. When I connect with my laptop (Compaque) and start both then only starting window XP message appears through projector and laptop works normally but again...


The setup is not correct. Check the requirements of the projector, (size, refresh rates etc.) and set the laptop up accordingly.
You will se the XP Screen because the laptop hasn't loaded any drivers yet and the screen is low resolution.
Hope that helps.

Hitachi projector problem


Many Hitachi projectors use 3LCD technology which supposedly makes colors more realistic. 3LCD means that the projected light must pass through 3 seperate LCD screens. Each screen has one color but when mixed, they form a nice picture. I would guess that one or more of the LCD screens have gone bad. That is a hardware problem that I would recommend talking to the manufacturer about.

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

Hitachi CP R555 Multimedia LCD Projector


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.
