Can any DLP® lamp be used with any DLP® TV?
No, the lamps are not interchangeable between all models or even between manufacturers. The Owner's Guide lists the correct Mitsubishi part number for the lamp assembly by model on the cover of the guide.
MEVSA recommends that you use only genuine Replacement Lamp Assemblies purchased directly from Mitsubishi or a Mitsubishi Authorized Dealer or Mitsubishi Authorized Service Center. MEVSA advises that replacement lamps obtained separately from the Lamp Cartridge and/or Lamp Assemblies obtained from unauthorized sellers may be incorrect for your television, may not fit or perform properly and may even damage your television. MEVSA can not be responsible for the performance, reliability or safety of any replacement lamps that are obtained from unauthorized sources.
When was my HDTV built?
On the back side of the television is a label that lists the month and year of manufacturing.
There is hot air blowing from my television, is this normal?
It is normal to have warm or even hot air exiting the HDTV. Air temperature will be higher if the room temperature is high. Ensure there is enough space to allow cool air to circulate to the back of the HDTV.

What is the difference between a DLP® and a LASERVUE®?
televisions use a lamp as a light source to display a picture on the screen. The LASERVUE is a DLP television which uses lasers to illuminate the screen. Lasers maintain a constant brightness and color over a long period of time. Lamps dim over time and need to be replaced.
What is ISFccc?
Imaging Science Foundation (ISF) Certified Calibration Configuration (ccc) is for HDTV products that are "Engineered for Calibration". Those products can be calibrated for optimal performance for both Day and Night modes. Available on 2009-2010 model years.
There are black bars on the sides of my picture.
Widescreen televisions capable of displaying aspect ratios of 16:9 have the ability to display non-HD content in its original aspect ratio and display black side bars on the left and right edges of the picture.
These televisions also have the ability to stretch the aspect ratio in a variety of ways. Press the FORMAT button on your remote (or the MORE+0 on 2009 models) button to cycle through the various formatting options available.
Why do some models of Unisen™ TVs have different numbers of speakers?
models are capable or reproducing surround sound audio. The additional speakers on the step-up models provide improved audio performance.
Why does the lamp in a DLP® HDTV need to be replaced?
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 HDTV while it is operating, the selected lamp mode, and your viewing patterns. Warmer air or poor ventilation shorten the lamp life, as does setting Lamp Energy to Bright and turning the television on and off frequently.
How often will I have to replace the lamp in a DLP® television?
The life expectancy of a DLP®
lamp depends on many factors. There are some things you can do to help extend the life of your lamp:
- 1. Don't unplug the AC cord while the cooling fans are running.
- 2. Set the lamp mode to 'Standard' instead of 'Bright' if your model HDTV has that option.
- 3. Periodically clean any dust build-up on the lamp wire mesh as well as any areas near the air intake vent for the lamp.
- 4. Remove any restriction to air circulation so as to allow for at least four inches on the sides of the HDTV as well as the back of the HDTV.
What are picture modes?
Picture modes allows you to get the best picture under different lighting conditions.
* Personal opinions may vary, use the picture settings that you prefer.
Feature available on 2008-2010 model years
- Use Brilliant under bright light conditions.
- Use Game when using game consoles.
- Use Bright for daytime viewing.
- Use Natural for most nighttime viewing.
The Status light on the front of my HDTV is blinking green
It is normal for the Green LED to blink while the HDTV is in the booting up process for 20-60 seconds.
If blinking continues for more than 60 seconds (and you are not doing a software update) unplug the AC cord from the wall power outlet. Wait for 60 seconds before reapplying power to the HDTV.
If HDTV still does not fully power on you can remove all connections to the HDTV (such as your Blu-ray or DVD players or set-top-boxes) and then unplug AC and try again.
Note that a slow blink means a timer is set or that your DLP®
is in the "cool-down" period.
The Status light on the front of my HDTV is a constant red
If you receive a Solid Red LED indicator on the front of your HDTV you should first unplug the AC Cord from the wall power outlet and wait for 60 seconds before reapplying power to the HDTV.
If after several attempts the HDTV has not fully powered on and the LED on the front of the HDTV is still Solid Red you may want to reseat the lamp.
If reseating the lamp has not resolved the issue then contact Mitsubishi Consumer Relations to order a replacement lamp.
The Status light on the front of my HDTV is blinking red
LED blinking red typically indicates that there is a fault with the HDTV.
Unplug the AC cord from the wall power outlet and waiting 60 seconds before reapplying AC to the HDTV.
If after you have attempted to recycle the AC power and the HDTV has not fully powered on please contact Mitsubishi Consumer Relations.
The Status light on the front of my HDTV is blinking yellow
This indicates that your lamp door cover is not installed or not installed correctly. Ensure that the door is flush against the back of the HDTV and screwed in.
My AV Reciever (Surround Sound Device) has no sound from the TV
- To ensure you receive the best audio quality possible, connect your audio source directly to your AV Receiver, not through the HDTV.
- NetCommand® may not be set up correctly. Check your owner's guide.
- Set the audio output format to PCM instead of Bitstream.
What is CEC?
CEC (which stands for Consumer Electronic Control), also called HDMI®
Control, allows the control of HDMI®
devices by other HDMI®
devices using signals sent back and forth over the HDMI®
cable. The benefit is a unified control using one remote control without changing control modes of the remote control.
My CEC is not functioning properly
To resolve conflicts, each device has the ability to turn off the CEC or HDMI®
Control in the menus of each device.
What does the system reset do?
System Reset is an easier way to restart the HDTV's operating software instead of unplugging and re-plugging the HDTV's power cord into the AC socket. System reset is similar to rebooting a computer.
Closed Captions are not working
Closed Captions exist only on signals received on Antenna, Direct Cable (without a cable box), Composite Video (the single yellow video cable). HDMI®
and Component sources (such as your cable box, satellite receiver, DVD players, and Blu-ray players) have their own Closed Captions Decoders or Sub-title Decoders which will insert the captions/sub-titles as "open captions" into the signal before sending them to the HDTVs.
What are the specifications for upcoming products and accessories?
Specifications are available for released products. Any news of upcoming technologies can be found in the press release section of the main website.
What are the viewing angles per size of a TV?
Viewing Angles are based on the display technology, not the HDTV size.
the horizontal viewing angle is between 120°
and 140° (60° to 70° on each side of center)
For LCD and LED LCD it would be between 160°
and 178° (80° and 89° on each side of center)
. **Recommendations only, personal opinions may vary.
What are the viewing distances per size of a TV?
The minimum recommended distance is approximately three times the screen vertical height. Below are listed these minimum recommend distances for our 1080p DLP®
Home Cinema sizes rounded off to the nearest foot. *
60" HDTV = 7'
65" HDTV = 8'
73" HDTV = 9'
82" HDTV = 10'*Recommendations only, personal opinions may vary.
Are the Mitsubishi TVs compatible with HDMI® 1.4 version?
Source devices that output HDMI®
1.4 are backward compatible and will operate with any HDTV with an HDMI®
1.4 features will not be available to any HDTV that does not specifically list support for the feature in question.
What model HDTV do I have?
A label located on the back of your television lists the model number, serial number, date and location of manufacture. The model number often starts with the letters "WD" if it is a DLP®
, "LT" if it is an LED or LCD or "L" if it is a LASERVUE®
The Status light on the front of my HDTV is a constant yellow
When the LED is Solid Yellow the internal temperature has exceeded the specified levels. Typically the cause of excessive heat is poor air circulation.
If your Mitsubishi HDTV has a solid Yellow LED leave the HDTV in the OFF condition for at least 15 minutes to allow it to cool down.
- Ensure there is plenty of room between the edge of the HDTV and the surrounding walls or cabinets of the entertainment center. A gap of at least 4 inches around the entire HDTV is recommended.
- Do not operate the HDTV in an environment that has excessive heat. If only hot air is being circulated to the rear of the HDTV then the temperature inside of the HDTV will only increase.
If after you have ensured proper airflow and room temperature the problem still persists it could indicate an internal problem with the air flow. Contact Mitsubishi Consumer Relations.
What is the software version of my TV?
Press the MENU button. In the bottom left or right corner of the display there will be a series of numbers such as 10.xx or 11.xx. Those numbers are the version of software installed on your TV.
How should I clean my TV screen? (737 Series TV)
Please refer to page 71 in the full owners guide. This information is not in your Basic Owners Guide that was included in your TV packaging.
I have a colored light that is constantly blinking or lit on the front of my TV. What does this mean? (737 Series TV)
Depending on the color of the light and whether it is blinking or continuously on, it could mean a wide range of conditions. Please refer to page 9 in the full owners guide.

televisions should not be operated below 32°
F or above 104°
LCD/LED televisions should not be operated below 41°
