The image is so dim. The projector is working properly then suddenly the image is so dim. The error indicator is not lighting up, it projects the image but it is so dim
I changed the bulb and since then the projector light got very dim.

I'm not familiar with your specific model, but are the units LCD or DLP? What I've seen in LCD projectors used in schools, museums, etc. that are left-on for several hours per-day, is that the UV filters in the optical blocks will fail. They usually change to an amber-brown color and block most of the light. It's the equivalent to putting sunglasses on. Do the units also exhibit a greenish-yellow tint instead of proper color?
1 red blink every 2.5 seconds indicates a cover error-- for this check the lamp cover
2 times red blinks very 2 seconds indicates temperature error. for this let the projector cool off check filters and fans that there is no blockage of air for proper cool down
3 red blinks every every 2 seconds Power error. incorrect voltage input or internal malfunction.
4 red blinks every 2 seconds indicates Fan Error check the fans make sure they are working and not blocked or need replacing.
i have nothing on 6 ligths go ahead reconect and check for proper count. hope this information helps.
Best of Luck.
You need to remove the cover and check where the lamp light is being attenuated in the optical path from the lamp to the front lens. I would try using a 12volt 50W halogen lamp in place of the real lamp and shine it into the optics system, and see where the brightness starts to go bad.
I've got the same problem. Just replaced the bulb but the image is no brighter. Our unit is two years old and operates about 6 hours a day. It is dimmer and more out of focus when run from a Windows computer.
before installation of a new lamp your projector need a service due to dust your LCDs and analysis block not pass on the light properly and now you get a multi color background and very dim image.
so you service your projector to a technical person
I have changed the bulb on my LG projector recently. I found the rotating colour wheel to be full of dust. Upon opening the cavity where the light is redirected and reflected onto the imager, I saw all mirrors also had a layer of dust. I don't think it was so dirty that it affected the brightness of the image, but I cleaned it anyway using an earbud. I cleaned both sides of the color wheel as well. You need to be careful in working with the optics of the projector!
