Remove upper back. The mirror is right there facing down at 45 degree angle to the three projector lenses and the screen. It is a silver polyester film laid over a backing board. I cleaned mine successfully with very soft paper towel (Bounty) and 70% alcohol. Rub gently in small circles until the alcohol is dry. If you just wipe the alcohol across the surface it will dry with a bad white haze. You have to rub it dry and then keep moving on until whole mirror is cleaned. This is only necessary if there are smokers in the house. Cleaning gets the nicotine film off the mirror. Best to not clean if possible.

MIRRORS NEED CLEANING


Remove the cover around the front screen...this is the best way to get to the mirror. You may need a service manual if you can't figure it out how to get it off...but in most cases the trim will snap off.

Do I need to clean the screen on a DLP television? I have only changed the bulb. I feel like the picture is getting less sharp.


Not the screen so much as the projection mirror which is located on the rear wall of the Set. If the mirror gets dull it can make the picture dim and dull looking. Cleaning the mirror will help. Some models have a small mirror which projects the image back onto the rear mirror. Dont use windex, just a damp cloth then dry good.

The picture is dull, what i have to do for the TV?


The usual cause of the DLP's geeting dull is the front small projection mirror gets dusty and needs cleaning. The mirror is located dead center in the front after removing the screen assembly. Its a small mirror directly in front of the lens assembly of the light engine.

Dull/cloudy picture


If the set is 4-5 years old, it probably has dust on the lenses and mirror.
This can cause a murky picture.
If you can remove the front screen assembly, you can gain access to the lenses and mirror. Clean with a dry micro-fiber cloth very gently.
Hope this helps,
Dan

There are a few malfunctions that can cause such.

ONE: Mirrors out of location. But it usually throws the picture off center, also. This can be caused if the set is dropped or kicked badly.

TWO: Out of focus. Can be caused by drift of the circuits or from a malfunction of the video drivers. You can check this by going to the crosshairs and see if the lines are sharp and narrow. If not, then the focus is off badly - most likely the blue gun. You may be able to set the focus and other levels for brightness and contrast and color to optimize this weakness as these are all somewhat interrelated, especially in the extreme settings. You can make adjustments for these above what is available from the OSD by getting into the service mode. See this web site for instructions on how to enter it. http://www.fixyourowntv.com/servicemenu.php

THREE: Worst case is the blue gun or projection tube is failing and needs replaced - which I don't recommend due to the very high cost of doing so.

FOUR: And it is possible the blue gun/tube has been knocked out of alignment by dropping or moving the set.

I favor the focus adjustment as the first remedy to try. You can do that yourself. But if it turns out the mirror is out of location or the blue gun is defective you will need a technician for help on those items.

Sounds like you need to clean the lenses and reflective area inside your set. It is easy and all you need is a screwdriver, windex and a paper towel. UNPLUG YOUR TV.   Take off your screen and screen protector and safely set them aside. 
Clean only the lenses ( glass part) and the reflective mirror type area on the top of the inside of your set.  It will look like new. You need to do this at least once a year.
