Question about ViewSonic PJ255D DLP Projector

2 Answers

Vt45 projector turns off without notice.

The projector turns off while in use. It doesn't really needto be "too hot". It may be in the first few minutes of use.

Help! We've already had it repaired once before. It sometimes seems to help when the filters are vacuumed very clean. That's the advice we received before.

Any suggestions will be truly appreciated. :D

    We had that same problem, but now the lamp won't come on at all, how can I reset the filter timer without the lamp. It went for a long time giving the error message to change the filter (which we did, but it still gave the message). We're a very small church and can't afford to replace the bulb again (we just did about a year ago)

    My projector was exactly 1 year old and working fine till it started to switch off after around 3 mins. I've cleaned it out and reset all counters. This has had no effect. the fan is working and I don't believe it is to hot. Also once it has powered down no LED's are lit. I need to disconnect from the mains and wait for a period of time (not sure 5-15 mins) till it will respond. Any help gratefully recieved

You've probably replaced your projector since this question is a year old, but I had the same problem. The problem is with bad capacitors. A friend of mine works at a television repair center and was able to replace the bad caps with generic off the shelf replacements. The cost was less than ten dollars and my projector is as good as new.

Hi there

What brand is this Projector ?

Check if the unit has a Filter Timer ? If it does have one - check the hours on it and reset it.

If the problem stil occurs or there is no filter timer in the Menu - check that all your fans are running.

Hope this is of help

Epson PowerLite 410W projector (used for a smart board in a classroom) won't project anything or even turn on. Power button (maybe lamp indicator light? I don't really know anything about this...)...


It seems you assume that it is not an overheating problem.
The problem is, the bulb gets really, really hot when using the projector. It doesn't matter whether it has been there without any usage. As you switch it on, it will start to get hot.
But the lamp or other parts of the projector should not get too hot. To control the temperature, air is moved through the projector with the help of fans. Air enters through air filters and move through the projector absorbing heat from hot parts. This prevents these parts from getting overheated.
But what if air doesn't flow freely? Then the parts CAN get overheated.
First, switch on the projector and check whether you can hear the fans working.
Next, switch off the projector and remove power cable.
After about 30 minutes, remove the cover and check whether the air filters are blocked. If they are, clean them with a small brush.
This would probably solve your problem.

Steady red status light on NEC VT45 projector. Would not POWER ON. LAMP was replaced with a new one


the power supply on that model seem to go bad after a while. the caps aren't properly reted it's power needs. they dry up. if you are good at soldering, replace c1 on the board (big cap) with a cap that has a slightly higher voltage rating. or replace the whole power supply. you might not be able to get one from nec, but you can try www.projectordoctor.com

VT45 Projector: Blue pixels throughout screen


If the problem is what I describe as a blue haze over the entire image projected, I was told this is a defect in the cable - we have a Dell Video Projector 2300 - and it takes only a dell VGA cable.

So, the problem is in the cable - solution is replace cable.
