Question about InFocus X1 Multimedia Projector

Proector image is dim

The image is dim, but when I replaced the bulb with a good one (bright bulb) it was still dim.

When I tried the bulb in a "good" projector the image was bright but it "flickered".

I updated the "firmware" on the projector, it changed nothing.

Is it the bulb or another component? Is there such a thing as a video card on the projector?

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!

Unfortunately dim image is normally due to a defective lamp assembly. I'd recommend removing the lamp and inspecting its condition. You'll notice black corrosion build up or a bubble is starting to form around the filament of the bulb if it is what's causing the dim image.

Yes, as bulbs age they will begin losing brightness. Most projectors have a bulb life hour clock, that measures the number of hours a bulb has been used. Usually you can pull that up within the menu of the projector. Also that particular model has what is called "Eco-Mode" and when engaged dims the bulb by 25% to cut down on power consumption.

Typical life for a lamp in that projector is:

3000 hours on Normal mode
6000 hours on Eco mode

You can expect a brightness loss of 50% when you are approaching end of a lamps life.

My headlights are really dim at night. But everyone says there fine. what should i do?


The headlights on my Tahoe are dim too. It's also a 1999. I replaced my bulbs with Silverstar's but it was still dim. I used Mequiar's Headlight kit to polish off the yellowing and oxidized headlight's and it really made them look good but they are still not bright. They look bright but the light hitting the road is still weak. It's because the inside of my headlights are a little bit cloudy still. The heat damage from the bulb made the insides cloudy and the light is still weak on the road at night. That's all I can do unless I replace the headlight assemblies. Much money and not super simple to do. I have very bright bulbs just cloudy housings that still don't allow the beam to fully shine through. I don't know if that is your issue but I hope this helps.

Test the leads to the bulbs while the low beams are on and then when the brights are on. If you have good bulbs & fuses with no power on low, the problem is most likely the bright/dim switch.
Not exactly sure of the Acura layout, but the covers over the steering shaft should remove with several screws to allow access to the switch (usually the turn signals are also the bright/dim switch) Test the leads out to the headlights from the bright/dim switch, that will tell you if the switch is bad.
Airbags are closely involved with this removal/replacement, it is NOT recommended for a amatuer to undertake.

Image is dim. How do I adjust brightness


You can adjust the brightness through the user menu, under the picture option. You might want to look at your bulb. It might be time to replace the lamp.

Headlight one side works on bright the other side works on dim


Try swapping the headlight bulbs or buying a known good bulb and testing that way. Sounds like a shorted bulb filament issue.

Check you manual for a dual brightness control that may be activated or even stuck at low level. The manufacturers web site may have a technical help team to consult - have you tried?
