CAUTION
BURN DANGER!  HOT SURFACES INSIDE!
Touch lamp cartridge handle only.  Do not touch lamp or lamp car-
tridge housing.  Keep lamp cartridge horizontal during removal.  Do 
not tilt as glass may come out and cause injury.  Replace lamp car-
tridge only with the same part number 915B441001.

Lamp
The light source for this television is a 
lamp, which is part of a lamp cartridge 
assembly.  The life of the lamp can 
vary, based on the lamp itself, the air 
temperature around the TV while it is 
operating, the selected lamp mode, and 
your viewing patterns.  Warmer air or 
poor ventilation shorten the lamp life, as 
does turning the television on and off 
frequently.
Mitsubishi warrants the lamp for one (1) year from the date of original 
TV purchase at retail.

  Cl eaning Recommendations
Normally, light dusting with a dry, non-scratching duster 
will keep your TV clean.  If cleaning beyond this is 
needed, please use the following guidelines:
First, turn off the TV and unplug the power cord from 
the power outlet.
Exterior
Occasionally clean dust and debris build-up from the 
air-intake grilles on the back and sides of the TV.  Clean 
using a vacuum cleaner with a brush attachment.
Top and Sides of the TV 
Gently wipe down your TV with a soft, non-abrasive  
cloth such as cotton flannel, microfiber, or a clean 
cloth diaper, lightly moistened with water.  Dry with 
a second dry, soft, non-abrasive cloth.
For oily dirt, add a few drops of mild liquid deter- 
gent, such as dishwashing detergent, to the water 
used to moisten the cloth.  Rinse with a second 
cloth moistened only with water.  Dry with a third 
dry, soft, non-abrasive cloth.
Screen
Follow the instructions for the top and sides, wiping  
gently in an up and down motion.
Clean the entire screen evenly, not just sections of  
the screen.
Do not allow liquid to drip down the screen, as  
some liquid may enter the TV through the gap 
between the screen and screen frame.
You may purchase Mitsubishi Screen Cleaner, part  
number CLEANER-VSS, by calling (800) 553-7278.
General Cleaning Precautions
DO NOT allow liquid to enter the TV through the  
ventilation slots or any crevice.
DO NOT use any strong or abrasive cleaners, as  
these can scratch the surfaces.
DO NOT use any cleaners containing ammonia,  
bleach, alcohol, benzene, or thinners, as these can 
dull the surfaces.
DO NOT spray liquids or cleaners directly on the  
TV’s surfaces.
DO NOT scrub or rub the TV harshly.  Wipe it gently. 
Appendix A:  TV Care, continued

TV  Re set Comparison Guide
You can resolve many common TV problems using the 
reset functions described in the following table.
IMPORTANT
Before you change sound or picture settings:  If 
picture or sound settings seem wrong for a broadcast 
channel (a channel from the 
ANT input, a cable box, or satellite receiver), first check other channels from 
the same input before changing settings.  If most other 
channels from the same input seem correct, there is 
likely a problem with the broadcast rather than with the 
TV.  Use care in this case, as changes you make to fix 
problems on individual channels also affect all other 
channels on the same input.
