The entire screen unit can be removed but first remove rear cover and look at the lens--clean with a lens cloth etc----peek up inside and look at the mirror--if not dirty or smudged just clean the lens.
removing the screen with its frame can be tricky--easy to damage the screens etc. Removal usually requires front speaker grill to be removed first---most just pull off but a few are secured from rear by some screws.
With it off look to see if at bottom of screen there are a row of screws--if the entire front unit can be removed it will pull out at bottom and be snapped in place.
A better suggestion is look at rear of set above back cover--if the upper part is plastic--it with the back removed can also be removed--careful as mirror is bolted into it---that way you can clean the mirror and get at the lens for the tubes without trying to remove screen unit--some of the smaller sets this is the ONLY way to get at the mirror.
Yes a number of screws but if plastic upper rear comes out with mirror much easier and safer way.
I received a similar HP Laserjet Color Printer with same issue for repair/ maintenance a few months back. Actually the problem is with the printer design not the magenta cartridge and it needs professional hands for servicing and cleaning. The mirrors which reflect laser beam get covered with dust and toner. hence the image is not produced properly. note that first magenta goes off, followed by yellow, then cyan and lastly black. this is because of the mirrors placement inside the printer.
Rest assure that the printer requires ONLY CLEANING OF THE MIRRORS, which are inside the printer.
Clean them yourself with dry n soft cloth (if you are familar with such tasks) or get it cleaned by any printer repair/ service professional. Please note that the mirrors, lenses and scanner assembly inside such printers is extremely complex and can get damaged very easily especially the mirrors.
Clean the small front projection mirror. That mirror can get dust on it and will cause the projected image to appear dull and dim and cleaning that mirror will usually restore the brightness and crisp details in the image.
When the color wheel starts to go out, what happens is the picture will usually be very faint and pulsate with no color (just black and white). This will last for about 10 to 20 secs then the projector will shut off. If you have a clear picture then it could be your lamp. Need more info. Does the projector shut off after the red light appears? Also you can pull the lamp out and clean the contacts with electrical contact cleaner which can be bought online or at your local radio shack. Pick up some denatured alcohol while you are there. While your lamp is out, use compressed air to blow out dust and debris from the fans and color wheel. You can clean one side of the color wheel very easily while the lamp is out. Use a q-tip with the denatured alcohol. Wipe from the middle towards the outer part gently. If you do it at a slight angle you can turn the wheel while you clean it. To clean the other side requires removal of the outer casing. Make sure your lens is clean as well. Use the compressed air to remove dust/debris from it. If you notice smudges on the lens, you can clean it with the denatured alcohol. Do not use any other type of cleaner on it and use a very soft cloth, preferably one made for cleaning plastic eye glasses. Be very gentle as the lens can easily be scratched. A build up on the lens can cause the error you described as well. If you are able to get into the menu, check and make sure your lamp hours are not maxed out. If they are reset the counter.
Because of age of use, dust covers the PRT lens (Red, Green and Blue) and Mirror as well. You can clean them with a soft cloth, with care. It is easier if you can remove the Screen (front side) but it is kind of complicated. The easier option in most of the Rear Projection TVs is to remove the lower cover and check if you have access to Lens and Mirror. Avoid excessive pressure in lens and specially with the mirror while cleaning is made. This process can make the picture clearer, specially if dust is excessive.
as i previously posted, my picture was dim, muddy looking after
replacing lamp with osram lamp. i fixed mine by taking the screen off
and cleaning the small mirror. it had a thick layer of dust on it,
cleaned with a microfiber cloth. no water, no glass cleaners. i also
used a very fine new small paint brush and dusted the projector lens
which also had a dust film. brightness, contrast and clarity returned!
Well I finally had the TV picked up by a Toshiba recommended repair place and they are saying that it is a bad Optical Block, also known as the Light Engine. Total for pick up, parts and repairs is $827.00. This seems ridiculous to me when brand new TVs are so much cheaper now. I don't think I will pay that much to have this one fixed.
try to use an air spray for dust. get the lens off and clean above the
miror. with the air spray the dust will disapear. dont use air pumps
becose u mes it up. and dont use compreset air from regular compresor,
u will get oil on your lenses.
There is black insulating foam that surrounds the projector and it may be displaced to one side.This leaves about an 1 inch opening around the projector lens and that could be the source of the problem,dust being blown into the compartment with the mirrors. Cleaned the mirrors really well and used double stick tape to reattach the foam to the plastic frame and this will closed off the opening that maybe letting the dust into the mirrored area of the TV.
