NEC LT280 Projector review?




Calvin W


Hi -
I am considering of purchasing the NEC LT280 Projector for $800 for my home tv/theater, can anyone advise me if this is a good purchase? I can't find any reviews on the NEC LT280 Projector.


Thanks,
JP



Answer
First, here is a link to your projector.

About the only thing I can see that might prevent me from purchasng it is the rather low Contrast rating of 600:1.

Here's a couple more that I can recommend, that are cheaper than the one you are looking at, if you look around.

I see the one you're looking at is 2500 lumens which is way more than you need. Increase your contrast and decrease your lumens to about 1000 and you can save some $$$ and get a better picture.

My NEC NP400 projector is not coming on?




Saadu


When i turn it on the status light and power botton become green as if it is trying to come on, after few second it sounds beep beep and then both power botton and status light goes orange. The lamp light is not coming on. What do i do?


Answer
The lamp is not striking. Read your manual. Take the lamp out and then reinsert it to make sure it's not a bad connection. If you still can't get the lamp to strike then it is likely that the lamp has expired. Buy a new lamp.

If this is already new lamp then the chances are that the projector's lamp ballast circuit is faulty. The ballast acts like a big battery. It stores up enough electrical charge to create the big spark required to start a lamp. Projectors use arc lamps. The electricity has to jump a small gap to create the arc. Mains electricity is not enough on its own, that's why the projectors need a lamp ballast.

If the lamp ballast is faulty then it will need to be replaced. The cost of a new ballast is often more than the price of a lamp.
