How to clean air filter on a Hitachi CP-X345 LCD Projector

I got a Hitachi CP-X345 lcd projector. I know where the filter is and how to get the grey thing out. You know - first you remove the cover - light grey plastic and underneath that there is this dark grey filter.  I have gently washed it with a wet cloth - also the rest of the projector from outside. Then i left it for some minutes and then i resampled it. But it stills says the same thing and the bulb where it says "Temp" (temperature i guess) is red. 
So how do i clean it so it doesn't say that i need to clean it?? Shall i use canned air?, wash it under war/cold/normal water for some time and then let it air dry / do it myself? Hope you understand and you are able to answer quick. Thank you.

- you may use movie or text but if you are able to use a movie it would be super!! - i noticed that many more have the same problem but none of them got solutions.

Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

  • A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
  • A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.
Goodluck..

Hi there

Check if both your filter timer and lamp timer is reset.

If it is then there is a Mainboard fault and it will need repair or replacement.

SOURCE: Resetting the air filter timer

If you do not have a remote here is how to reset the filter time. Use the "Menu" bottun to get the "easy menu" to display. Push the down arrow until you get to "Filter Time," then push and hold the RIGHT arrow to reset the filter time. DO NOT try to reset using the "Reset" option on the easy menu, it will not work.

SOURCE: Hello Wardens wife

What you want to do is go to the advanced menu, find the filter time and using the remote hold down reset button for 3 seconds or so while the filter time is selected. This will bring up a reset menu and reset the timer.

Hiya there, just worked out how to reset the filter timer so for those that need to know here's the solution;
Bring up the menu and go right the way down to "Option" where it shows you the lamp and filter hours.
Next highlight/select the filter timer section and while its on there hold the RESET button on the remote for 5 seconds.. this then pops up with a resert option and hey, 0h again, good as new! :-)
Oh and if you dont have a remote, just hold the right arrow button instead for 5 seconds in place of the reset and follow instructions as above!
Hope this helps.
Regards,
Omar.

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.

Lamp and temp blink red


Check your owners manual. This means that the air filter needs to be cleaned or that the projector has become too cold. My guess is the first one. The owners manual has instructions for cleaning or replacing the air filter :)

Good luck!

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
