Question about ViewSonic PJ400 LCD Projector

My viewsonic pj400 projector switches itself off

My 4year old viewsonic pj400 projector switches itself off after running for a few minutes. I have cleaned the filter and ignored the filter timer reset warning notice (as I have always done), but then a minute later the projector goes into shut down mode, accompanied by a slightly more higher pitched fan noise. Does it need a new bulb or is it something else?

Hello

i have the same problem, a clear image, the the projector shuts down, turn the fan on, and "lamp" blinks.

i returned my projector to viewsonic service center, they told me to change the lamp.

the problem is that a lamp is very expensive!

Hi folks! I have a Viewsonic PJ400 projector. He


Which "lenses" did you clean inside the unit. It would seem that you have misalignment of the lcd panels or the phase setting may need adjusting. What input are you using and what vertical frequency is the signal using?

I turn on my Viewsonic PJD6251 but the lamp does not come on, and after a few seconds I get 2 red lights TEMP and LAMP. It is new, only 2 weeks I barely used. Good care.


sounds like a bad bulb

projectors get a resistance reading from the bulb and if it doesnt get right value it will give you the double red lights

only other thing it could be is if the fans in projector are not turning on

call viewsonic and tell them issue and make them resolve issue

or

if unit is only 2 weeks old bring it back to store and get replacement or call viewsonic and get them to send you replacement unit - it is too new to mess with it yourself and take chance on voiding warranty

Model PJ556D will run for a few minutes and then shuts off. Once it cools down it will start back up, but shuts off again a few minutes later.


Hello, Greg.

The most common reasons are the temperature is too high or the ventilation holes are blocked.

Unplug the AC power cord, wait 5 or 10 minutes then turn back on.

There could be dust or the air filter needs to be changed.

Take the lamp cover off the bottom. It's possible that the screws holding the lamp are loose.

Hope this helps.

Lamp and temp lights come on after power up and stay on. Lamp only has 330 hours on it.


OK, that explains it. The bulb you have installed in the projector might be the original bulb that came with the projecoter when it was new. Just becuase it states 334 hours does not mean it is new. In fact, you could have a original bulb with 3000 hrs and reset the hour timer on the projector, which means your 3000 hour bulb might have 3334 hours on it because the person who owned it before you, reset the hour timer.. Best bet, buy a new bulb and reset the hour meter and see what happens. If you have the same problem, then your ballest might needs to be replace which is rare...
