When I turn on the projector the power light is green and the fans kick on. After a few seconds the power light flashes red and the fans get louder. Then it automatically shuts off. I've cleaned the air filters. I was thinking about replacing the lamp but the lamp replacement light isn't on.
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy.

try pressing and holding the enter button on the projector for about 30 seconds - this resets it. It worked for me!!

Just had the same problem. Based on other suggestions on here I tried resetting the overheat switch, and IT WORKED!
So, you have to pull the 6 screws (one of them is shorter than the rest, remember where it goes) that hold the top on the projector. 3 are on the back, 3 on the bottom - look for the arrows next to the screws.
Put the projector on it's feet, and pull off the top. The button wires will still be connected, so just hold onto the top and find the black circle/shaft above where the lamp is. The shaft has white paint on the top/tip of it. Push it down with a light amount of force. You should hear/feel it click.
Put top back on, put screws in, and you should be good to go.
Don't forget to reset the lamp replacement counter in the menus.

Welcome to resolve the problem if you please say what are the solution to me the same problem
SOURCE: Eiki lc-nb3s projector... fan comes on but no lamp
Please check on of these solutions :
1:Remove the lamp from the projector. Ensure that it has no cracks, discoloration or "smoky" appearance.
2:Try removing and reseating the lamp, or to try another lamp.
3:Reset your lamp timer. Most projectors have no way of knowing if you physically have replaced your lamp. They rely on the user resetting the lamp timer
4:Pull the lamp back out of the unit, give is a brisk shake and reseat the lamp. Occasionally there is some buildup on the lamp contacts or filament during manufacturing.
5:Are the input and output vents blocked or obstructed in any way?
6:Are the filters dirty or clogged? Most manufacturers will recommend filter cleaning on a monthly basis depending on usage
7:Remove any extension cords, power strips and/or surge suppressors. Many current model projectors will not even try to ignite the lamp if they detect drops or fluctuation in voltage supplied to the unit. This is a safety feature to reduce stress on the lamp.

I tried to count the blinks on the power light but after I counted nearly 70 blinks I just gave up.
