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

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.

My projector displays a message called ''check the air flow''. what can i do to remove that message?
Check Air Flow means that the heat sensor is activated. This message means that the air around the projector is not circulating well... causing the heat. Check that the projector has at least 2 ft free air around it. Also, make sure that the filter is cleaned.

Hope this helps!

Hitachi cp-rs55 not working,tic.tic.... noise coming from project
make sure you reset the lamp timer. Manual has the steps. Hitachi Performa CP RS55 3 LCD Projector

if the timer is reset, try cleaning the color wheel. Optoma HD20 Projector Cleaning this video is for an optoma but the color wheel is cleaned the same way in most DLP projectors. Dirty or dusty color wheel sensors cause the projector to shut down and act like its the lamp.

My CP-RS55 Projector Doesn't Work??? No Light?
Hi there

If the unit is brand new , they should replace it under warranty.

This is most probably a faulty Powersupply / Fanboard !

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.
