My projector keeps turning off after 20 minutes or so. The bulb is new but it keeps doing this.


Having the same pronlem with my one. Found that if you pull the power out and then replug it in then turn it back on it solves it. might happen a couple of times but it eventually stops. Annoying I know. Think its a heat problem. Let me know if you find a fix.. Cheers.

Pop saying check filter


Hi there...FIRST remove the dust filter and clean it with some compressed air, or you can leave it in place and use a vacuum cleaner hose to suction off the dust. Some projectors have a sensor that gets reset when the filter is removed. A lot don't. Check the onscreen menu for a reset option for the dust filter. This option may be only accessible with the remote control...DON'T reset the lamp hours! The most important thing with LCD projectors or any other projector, for that matter, is to keep the dust filters clean--think of someone putting their hand over your nose and mouth. The projectors emit a *huge* amount of heat and need plenty of air flow to remain cool. Also, the benefit of cool air keeps the delicate LCD panels from aging prematurely!---Rick

Hitachi CP-x430 "Check air flow"


I have run in to this time and time again. This is why I like to keep things clean. take the bulb out and blow the unit out with air and make sure you wipe off what you can with Q-tips The blub allows air to flow thew the filament so what ever dust that might touch the fillament while its burning will burn at a higher temp. this will send and indication to the unit to send a message that says replace bulb soon and If there is not enough air flow it will say CHeck air flow take the fliter out and clean it with water dont replace it. IF you do just buy a carbon pad and cover the hole(not recomended foir those who are not handy) but keep things clean and it will save you $ in the long run. How many bulbs do you want to buy?

Did you clean the air filter? You should vacuum it or use an air dusting can to clean it out.

Afterwards, reset the time in the menu. In the manual, it says you have to go in the menu to the OPTION submenu. Go down to FILTER TIME and hold the right arrow down for 3 seconds. It will then go into a mini-submenu that, when you press the up arrow, will reset the filter time to 0. The key is to hold down the right arrow initially for THREE+ SECONDS to get into the reset filter time menu. This is NOT the submenu that has RESET - EXECUTE. That is a different thing that doesn't reset filter & lamp time.

Here's the manual online:

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! =-]

This is a solution for the VT 480 by NEC for filter clean. on the left side there are two slots that have dust filters which can slide vertically to reveal micro screens that one can blow, tap vigorously, or vacuum to remove any dust build up. I hope this helps you with your unit.
