You will have to do some dissassembling of the cabinet to remove the screen and bezel assembly. If you are will to do this I can give you the directions.

SOURCE: Mitsubishi screen replacing
You must remove the front bezel and frame holder to replace the screen. You will usually see the screws holding the from from the rear of the unit. Once you get the frame off, take note of the way the old screen is installed. There is usually a label on one side near the bottom; the new screens must be installed with the label in the same location. The lenticular goes on the outside (facing the viewer) and the fresnel goes on the inside facing the mirror. You will be able to recognize the fresnel, it has a series of concentric circles that are raised on the sirface of the plastic Be sure to rate this solution.Thanks!

Actually the lamp with the housing is seperated fro the ballast, if you change the housing it will not chnage the ballast, you will see the cables unplugging when you pull out the housing, that cable leads to the ballast.

liquid is never good on those screens-
there are 3 layers to the screen, from inside out, a fresnel screen (etched circle pattern), a lenticular screen (ridge lines top to bottom), and a protective screen ( "Diamond Shield" tinted plexiglass).
the fluid will wick up btween these layers, turn black, then very very slowly recede leaving a waterline mark. It can take months for it to become un-noticeable.
cleaning is possible, but beware, any type of cleaning fluid or spray is going to simulate the exact same problem but to a larger area.
also introducing dust, lint or hair into the layers when separated is almost impossible to avoid.
these pieces, especially the lenticular screen are extremely fragile nylon plastic and is apt to split under its own weight when handling, so beware the project you are about to get involved in...considering the large size.
but it can be done.
Remove all screws around the screen frame from the back of TV and the lower sides. There will be a wiring harness that goes to front buttons- disconnect it. The whole assembly will come off the front of the TV.
Lay it on the floor face down. Remove the screws in around the inside of the screen. The screens are now ready to lift out, one at a time.
IT IS IMPORTANT to not attempt this by yourself. The screen are fragile and large and scratch so easily which appear as a white opaque area when reassembled. Have a helper. Wear cotton gloves while handling as finger prints will be noticeable after you reassemble.
ALSO IMPORTANT- these screen are oriented front and back...in other words they go together in a certain direction...on each screen layer there is a small sticker on its outer edge. Make note of its orientation and reassemble accordingly.
Clean with a cotton cloth and very very little "plastic glass gleaner" (if needed only!).
WIPE EXTREMELY GENTLY in the direction of the grooves on each screen layer- much like cleaning an old vinyl record.
The lenticular screen is the biggest worry as rubbing on the grooved side is so likely to cause damage. Perhaps rubbing should be avoided if possible.
Let them lay out and dry before reassembling. A bottle of compressed air is good to remove debris when layering them back together...a dust free environment is recommended.
Reassembly and installation is just the reverse of dis assembly- remember the wiring harness connector!
