  • Secure the lamp cover and the air filter cover of the projector body if the projector does not power on. Ensure that the power cable is firmly connected to the projector and an active power plug. If the projector was turned off and then on quickly--let it sit for 90 seconds before trying to turn it on.

    Replace the projection lamp if the projector will not power on or if the lamp indicator is flashing. Turn off the projector and let it sit for at least 30 minutes. Locate the lamp cover and remove or loosen the lamp cover with a screwdriver. Carefully remove the projection lamp from the projector housing using the handle, if available.

  • 3
    Place the new projection lamp into the projector housing and secure it to the projector. Replace the lamp cover and reset the lamp timer. Power on the projector to ensure the new lamp is working correctly.

  • 4
    Remove the projector from the enclosed area to allow air circulation if it constantly overheats. Place the projector into an open area and make sure there is no blockage for the ventilation holes. Unplug the projector for at least 45 minutes to allow it to soft reset.

  • 5
    Clean the air filter to allow the projector better air circulation. Turn off the projector and unplug it from the outlet. Remove the air filter cover and use a vacuum to remove dust from the area. If the filter is unable to be cleaned correctly or is damaged, then replace it. Pull the air filter from the projector and place the new one in the now empty slot. Close and secure the air filter cover.

Good Luck!
Turn the projector on and reset the filter time using the FILTER TIME item in the EASY MENU. Before taking care of the air filter, make sure the power switch is off and the power cable is not plugged in, then allow the projector to cool sufficiently. Taking care of the air filter in a high temperature state of the projector could cause an electric shock, a burn or malfunction to the projector. Use only the air filter of the specified type. Do not use the projector without the air filter or the filter cover. It could result in a fire or malfunction to the projector. Clean the air filter periodically. If the air filter becomes clogged by dust or the like, internal temperatures rise and could cause a fire, a burn or malfunction to the projector. WARNING Please replace the air filter when it is damaged or too soiled. When you replace the projection lamp, please replace the air filter . An air filter of specified type will come together with a replacement lamp for this projector . Please reset the filter time only when you have cleaned or replaced the air filter, for a suitable indication about the air filter. The projector may display the message such as ?gCHECK THE AIR FLOW?h or turn off the projector, to prevent the internal heat level rising. NOTE (1) Press the MENU button to display a menu. (2) Point at the FILTER TIME using the ??/?? button, then press the button. A dialog will appear. (3) Press the ?? button to select RESET on the dialog. It performs resetting the filter time.

How we can clean airfilter because message is appearing regarding clean your air filter


check in the menu to see if there is a filter timer that you can reset. if so, reset it. if not, there is an air flow sensor on the projector that will send that message if the air flow is decreased so the projector does not overheat. find the filter and remove it. blow it out with canned air and blow out the projector as well. replace the filter and enjoy!

My VT440 says this when it gets to it's pre-defined service life. (a certain amount of hours)

As long as you pop the filters out regularly and clean them (I use a vacuum cleaner) you shouldn't need to replace them.

After that, go into the projector options (with the remote control) and reset the factory defaults... otherwise it has no idea that you have actually changed the darn thing and keeps complaining no matter what! =-]
