How can you tell when the bulb is about to go?

Hello, have the Benq W1070. Lately it looks like the picture is getting more washed out. Is this a sign that the bulb is starting to go?

Thanks

It will keep getting dimmer so if their is ambient light in the room then yes it will look more washed out.

All projector lamps dim with age. If the image is getting more and more washed out from the same amount of ambient light that's simply a function of the same amount of ambient light having a larger and larger effect on an increasingly dimmer lamp. As to being able to predict when it might completely fail there's no way. Manufacturing variances and different use patterns mean that, like snowflakes, no two projector lamps are exactly alike. At some point some will simply dim to nothing and a small percentage will fail catastrophically. When the image quality degrades to a certain point most people will want a new lamp to restore the projector to its original bright image. YMMV.

Thanks guys. I forgot to check how many hours are on it but I believe it is around 2,000 maybe?? I will have to check.

Something else happened. I was watching something, and it looked washed out. But then all of a sudden it wasn?t washed out anymore. Like a switch was turned on or something. And I didn?t change anything. I was just sitting there watching. Is this the lamp still or would it be a projector issue? It went almost back to normal. Then I watched it again a day later and it was washed out. Weird.

The average W1070 lamp lasts more than 2,000 hours before it's too dim for viewing. Your latest description makes it sound as if the issue is not lamp related. It could be a cable issue, a failing component in the electronic circuitry or a source issue. If the issue occurs with different sources then you could rule that out. Another simple and obvious thing to check is to see that all of your cables are firmly inserted into their respective inputs/outputs. If you have extra cables you might also want to try at least temporarily replacing the current cables with the spares.

I will check the cables as well then. I have noticed that for some reason the projector has been dropping its connection a few times. The receiver's display doesn't change, but the picture drops then comes back after a few seconds. So I think it can be the cable or the projector at this point. I will double check the connection though.
