AIR FLOW PROBLEM IN HITACHI CP-RS55 - Computers & Internet

(1) While the projector running, press the MENU button to open the menu.

(2) Choose "OPTION" , then press ENTER button.

(3) Choose "FILTER TIME", then press and hold the RESET button for 3 seconds.
(4) Choose "RESET" .

Unclip the air filter covers and remove the filters, making sure not to let the dust stray into the machine.
Clean the filters. Depending on the type of filter, either wash them in mild washing up detergent or replace them if they are the paper element type.
That is all one can do without stripping the machine down and clean the vanes on the fans.

Hi....

Clean the filter

It will show you in the manual

Hi

The problem could be caused by the connection or configuration of your video equipment. Check the following:

• Make sure your component-to-VGA video cable is properly connected.



• Select Component Video as the Computer Input setting in the Signal menu.



• Make sure the connected video equipment is set up to output video to component video.

Hope this helps

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

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!

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.
