Are there any LEDs lit on the front of the TV?
Press the menu button on the remote. What is shown on the screen? (make sure the remote's layer switch is set to tv)
Do you hear any audio or sound coming from the TV?
Does the TV eventually shutoff and display a solid red LED?
Unplug the AC cord from the wall power outlet and wait for 60 seconds before plugging it back in. Then press the power button on the TV and if the condition of the TV is the same as before please call Mitsubishi Consumer Relations department for help troubleshooting (1-800-332-2119). Please have the following information ready: Model number, Serial Number, Proof of Purchase.
It is normal for the Green LED to blink while the TV is in the booting up process. Depending on the model it is normal for the Green LED to blink 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 TV.
Sometimes loading the software for your model can resolve this issue. Check our documents and downloads section.
If TV still does not power on you can remove all connections to the TV (such as your Blu-ray or DVD players or set-top-boxes) and then unplug AC and try again.
Is your TV recovering from a shutdown event?
Yes - the TV shutdown immediately before the blinking LEDA GREEN blinking LED means that the TV is in the process of booting up. There are many possible causes of a TV to shutdown and reboot. The most common is that invalid digital data was sent to one of the inputs (Antenna or HDMI).
Digital broadcasts from over-the-air television stations or from your cable company contain many forms of data. This data can be corrupted while being transmitted or it could be data input in an incorrect format. When the TV receives this data it could cause it to shutdown and reboot.
If this only occurs 1 time or 1 time every several months it should not be considered an issue. If the frequency of occurrence is more often such as every day or every hour you may want to contact the broadcaster/cable company or suspect your satellite box/dvd/blu-ray player.
Try to make note of what channel or source/content you were watching when the shutdown occurred.
A Solid Red LED typically means that the lamp failed to start.
First unplug the AC Cord from the wall power outlet and wait for 60 seconds before reapplying power to the TV.
If after serveal attempts, the TV has not powered on and the LED on the front of the TV is still Solid Red, you may want to reseat the lamp.
Procedure: Lamp Reseat
If your lamp has failed check www.mitsuparts.com for warranty eligibility or contact Mitsubishi Consumer Relations at 1-800-332-2119.
Be sure to get the below information before calling:
Check your owner's manual for detailed instructions on replacing your lamp. Check the documents and downloads a section for an electronic version.
If after reseating or installing a new lamp you receive a Yellow blinking LED, 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 TV.
If the door is properly installed please call Mitsubishi Consumer Relations. Please have the following information ready: Model number, Serial Number, Proof of Purchase.
Typically the cause of excessive heat is poor air circulation.
If your Mitsubishi TV has a solid Yellow LED leave the TV in the OFF condition for at least 15 minutes to allow it to cool down.
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 TV.
If the door is properly installed please call Mitsubishi Consumer Relations. Please have the following information ready: Model number, Serial Number, Proof of Purchase.
When the LED is blinking RED and YELLOW the TV has shutdown.
The sequence of blinking LEDs is a diagnostic code to be used by Mitsubishi Consumer Relations department to determine the faulty component.
You may 1st want to try to recycle AC power by unplugging the AC cord from the wall power outlet and waiting 60 seconds before reapplying AC to the TV.
If after you have attempted to recycle the AC power and if the TV has not fully recovered please contact Mitsubishi Consumer Relations. Please have the following information ready: Model number, Serial Number, Proof of Purchase.
Check that the AC cord is connected to an active wall power outlet:
Check that the problem is not the remote control:
If the TV turns on from the unit itself but not the remote, then likely the remote is broken or needs new batteries.
Watch "Remote Control" troubleshooting videoIf the problem persists please contact Mitsubishi Consumer Relations. Please have the following information ready: Model number, Serial Number, Proof of Purchase.
What speaker are you expecting audio from?
Watch "No Sound" troubleshooting videoCheck that you have the latest SW version installed (check our documents and downloads section).
Verify that the TV Speakers are enabled within the User Interface:
Check the MUTE setting:
Check your VOLUME setting:
What is the audio source device?
Which channel has no sound?
Verify speakers are functioning by doing one (1) of the following:
• Tune to an analog channel with snow/static and move the volume to at least 50%.
• Initialize the TV. Doing this process will reset the TV to factory defaults. Press MENU followed by 1 2 3. The TV will reset and reboot. After the process is completed, the TV will be on the Antenna input on channel 3. There should be audible "snow/static noise".
If you still do not hear any audio then please contact Mitsubishi Consumer Relations (1-800-332-2119) for further troubleshooting. Please have the following information ready: Model number, Serial Number, Proof of Purchase
Check the language settings:
The broadcaster of digital channels inserts digital descriptors about the audio format into the signal. Not all broadcasters are fully adhering to the ATSC specification and may be sending digital descriptors about the audio that the TV does not recognize.
If you cannot receive audio from a single channel then it is unlikely to be a fault of the TV and it is recommended that you contact the broadcaster of that channel or your cable provider.
Verify that the AV Receiver is enabled in the sound User Interface:
What type of device are you using to power the external speakers?
Connect this through the AC3/DIGITAL OUT (Orange RCA jack) connection on the back or your TV.
• Verify AVR is selecting the correct input (from TV) and that volume is high enough to be heard.
• Press INFO on your TV remote. In the upper right corner an icon should be displayed as an AVR symbol.
Connect this through the ANALOG OUTPUT (RCA jack) on the back of the TV.
• Verify AVR is selecting the correct input (from TV) and that volume is high enough to be heard.
• Press INFO on your TV remote. In the upper right corner an icon should be displayed as an AVR symbol.
What is the condition of the TV?
Check that the AC cord is connected to an active wall power outlet:
Test another device in that same wall outlet to ensure that AC power is active to that outlet:
Check that the problem is not the remote control:
If the issue persists please call Mitsubishi Consumer Relations. Please have the following information ready: Model number, Serial Number, Proof of Purchase.
Does a message appear on the screen prior to shutting down?
What does the message refer to?
Typically the cause of excessive heat is poor air circulation.
If your Mitsubishi TV has a solid Yellow LED leave the TV in the OFF condition for at least 15 minutes to allow it to cool down.
This message appears when there is no video signal. This can be caused by an invalid HD channel when you are using the TUNER input. Along with no valid video from a digital or analog device, such as a DVD player or Cablebox.
Check to make sure your remote or other IR/controller device is not sending a power down command to the TV. Other manufacturers remotes could be sending a power off command to the TV. Make sure all other IR sending devices are pointing away from the TV. If you have a controller device installed to the TV, you may need to contact the installer of that device to make sure it is not accidentally sending power off commands.
Check LED status after the TV has shutdown by clicking here.
What method are you using to connect to the internet?
What problem are you experiencing?
If you receive the loading icon on the bottom of the screen or a connection timed out error this means your TV has accessed the internet but cannot reach the final destination server.
The two most likely scenarios that will cause this is a firewall that is blocking the incoming content or that the bandwidth is too limited to receive the data.
Buffering is caused by limited bandwidth on your internet connection.
Most broadband connections share bandwidth with other customers in your area. As a result peak hours will likely show reduced performance.
For firewall settings, contact your network administrator.
Check your speed: http://speedtest.vudu.com/cdn1/
Contact your internet service provider (ISP) for more information on available bandwidth.
To start using the internet on 2010 model year TVs you will need to press the INTERNET button on your remote control. You will need this remote control to access the internet, older model year remotes do not have this button.

What problem are you experiencing?
Verify the connection on the back of your TV is connected to the LAN port with a CAT5/Ethernet cable that is connected to an open internet port.
Try bypassing your router/hub and connect directly to your cable/DSL modem.
If it works when connecting to your modem then there is a problem with your router/hub.
If you are missing your IP address, default gateway, DNS or SubnetMask data it means the TV found a network but is not allowed to connect to it.
