Re: screen is dim and not very bright
You can safely clean the mirror and lenses, it can greatly increase your picture if its dirty. If you unplug your tv you can safely remove the back and gain access to the lenses. All it takes is a philips screwdriver. After you remove the back, you can remove the light barrier between the upper and lower half to free up some room. Take a dry scratch-free cloth and wipe the dust from the lenses. If they're grimy, use a little lens cleaner (liquids used sparingly here, electronics don't like liquids, be careful) You can look up into the top and see if the mirror is dirty. A flashlight shined on it will illuminate the dust/dirt if its there. If you don't smoke you likely won't need to clean the mirror, but it may need it. Use windex or similar for tough grime.. I can usually reach up to get the whole mirror but I've heard of using a swiffer mop to reach the top. Removing the screen is difficult but possible if needed to get inside. Don't touch the back of the screen but lightly with a rag to get cobwebs, etc.

Yes, if this TV has a bulb it is likely to be the bulb.
I am not familiar with this exact model, but other LCD Projection TV will show dim picture after some time. Expected life of the lamps is about 2yrs. After 2yrs the picture will become dim. After 5yrs I am suprised it is even working.
Dirt doesn't cause this problem unless your are a smoker or have the unit "literally" outside. DO NOT try to clean it or let someone tell you to do it because it will cause more problems than it fixes.
Good Morning! With the 8 years operations of your emachines monitor, some of its electronic parts might incurred cold solder joint connections from its circuit board & possibly some of its Capacitor parts are already worn-out. please try to get assistance from an electronic service technician which will surely diagnose & repair the problem. best regards.
Most likely cause of your trouble is dust on the small mirror inside you set. Your DLP set has 2 mirrors not including the DLP chip itself which has about 500,000 tiny mirrors. The 2 mirrors reflect the DLP chip image to the screen you view. The first is the main suspect it's about 4inches by 7inches. It's mounted on the bottom center facing backwards. This mirror faces slightly up and somtimes after time dust, smoke, dirt settles on it . The second fills the space of the entire back of the cabinet but it faces down and takes alot longer to get dirty. The compartment is sealed but dust seems to find it's way in. If you remove the screws that secure the screen assembly from the top , sides and bottom. Make sure to have a friend available the screen assembly is delicate when it's not mounted to the cabinet. You can remove and clean the mirrors. These mirrors are glass and you can use glass cleaned. Don't use glass cleaner on the screen it's plastic. You can clean it if necessary with plastic cleaner only. Probably not needed. Good luck.
You need a professional.
Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.

I've had this same problem ongoing for a couple weeks. Finally, tonight it would shut off every 20-30 seconds, stay off for another 20-30 seconds then come back on. It turned out to be my bulb. I blew the TV out with compressed air, removed the bulb and disassembled it. Taking the bulb out of the plastic cage I then remove one of the metal screens at the top of the bulb, it just has little clips holding it in. I took a bottle of rubbing alcohol, some Q-tips and proceeded to clean the inside of the bulb through the screen hole. After cleaning the inside I put the screen back in, cleaned the outside of the bulb with a rag and alcohol, then reassembled everything. The TV is much brighter, I had to turn down the brightness setting and has been running the last few hours without an issue. You can avoid all this by buying a new bulb but I don't have the money right now to replace it and I'm cheap so I'll milk this bulb for everything it has. Heat kills bulbs so if you clean the screens and blow out the TV once every couple months you'll get a lot of life out of it..... I'm almost to 4 years on my original bulb and my TV is on constantly!! Good luck to all!!
I tooked the front screen off the TV set. I fallowed the instructions from another wrighter. The Bottom mirror was clouded with dust. I used a cleaner made for cleaning ipods and put it back together with instant success. I had not cleaned it since I got it almost four years ago. I just thought it was getting dim.
As far as the VCR playing black and white it also an easy fix. The Satalite Service man was swapping out my receiver and inadvertaly put the device on componite side of the TV. I put them back on Inpute 1 and 2 and they also work just fine. Thank you for your help.
reading other people porblems I was able to repair it on my own.
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!
I cant find you any dissasembly instructions but i know that if you go to your local wallmart they have headlight polishing kits for the lens. http://www.myheadlight.com/ thats the products websight. I hope this helped you choose what to use. Im sorry I couldnt help you get them apart.
All fillament based lights will dim as they age. Some of the newer/better types it will be unnoticible. If you are losing image quality or brightness you may have a bulb that is nearing the end of it's life cycle. A glance at you owners manual or the manufactor's website should give you an indication of the expected life of your bulb. Also most of the projector made in the past few years have a counter that tallies the amount of hours your bulb has been on. A more likely culprit is probably dust accumilation somewhere inside your projector. Most projectors have filters these days and need to cleaned at certain intervals and in certains ways. Not cleaning these filters can cause heat build up that can increase operating temps and shorten the life of your bulb and or projector. Or sometimes jsut fail and cause a dramatic decrease in image quality. Again these things are vendor/model specific so you will want to check with them about your particular model. Hope this helps.
