In 2001 to 2008 and 2009 models of Mitsubishi TV, a pulsing or blinking red light indicates that there is an internal fault with one of your TV’s fans.

It might be challenging to disassemble your Mitsubishi TV and replace the fan, but we will guide you through the process so you can do it yourself!

Follow the steps down below to identify a not-working fan and replace it:

  1. Identify the locations of all screws holding the lower back panel of your TV.
  2. Grab the appropriate screwdriver (based on the model) and undo all of the screws.
  3. Once the panel feels loose, pull it out and in the middle, you should see a fan.
  4. Turn on your TV and move away from the hardware.
  5. Determine if the fan would spin.

If the fan doesn’t spin, you can search for your Mitsubishi TV model and check the type of fan.

It is recommended that a technician takes a look, but if you feel confident follow the steps down below to replace the fan.

How To Replace Mitsubishi TV Fan?

Follow the steps down below to replace the fan of your Mitsubishi TV:

  1. Locate the power adapter of the fan and where it is connected to.
  2. Undo the 4 screws holding the fan into the cooling panel.
  3. Pull the fan slowly, but make sure that the cable doesn’t get damaged.
  4. Disconnect the power adapter once the fan has come out all the way.
  5. Grab your new replacement fan and remove the safety stickers.
  6. Connect the fan to the power adapter and embed the cable.
  7. Place the fan into the cooling panel.
  8. Install two of the screws so the fan becomes stationary.
  9. Correct the fan’s position and install the screws tightly.

Don’t put the back panel on yet. Turn on your TV and determine if the fan is going to start spinning.

If it doesn’t, go back to the steps above and make sure you’ve applied everything correctly.

Solution #2 Hard Reset The TV

We suggest performing a hard reset on your Mitsubishi TV, to clear out any potential power malfunctions.

It might not sound like much, but a hard reset works by cutting your TV’s electricity and this is exactly what we’re going to do now.

Follow the instructions down below to hard reset your Mitsubishi television:

  1. First, turn OFF your TV by pressing the power button on the remote.
  2. Unplug the power adapter from the outlet where it is connected to.
  3. Standby for 5 minutes (no cheating).
  4. Re-attach the power adapter once the 5 minutes have gone by.
  5. Turn ON the television and check the status lamp.
Pro tip: A widely populated opinion is that power strips are carriers of nasty power malfunction, which your TV can develop if plugged into one.

Solution #3 Close The Lamp Door

If your Mitsubishi TV won’t turn on red light, you should check if the lamp door is tightly closed.

If the lamp door is not closed appropriately, the TV will emit a red light and won’t be able to turn on.

Inspect the lamp door and make sure that it is pushed all the way in.

Once you’re certain that everything looks fine, restart your TV and determine if that has brought any change to the red light situation you’re getting.

Tip: If the TV does not want to start, open and close the lamp door.

Solution #4 Replace The Lamp Safety Switch

Even though this might not be directly related to the blinking red light of your TV, the safety switch could have gone faulty.

If that’s the issue you’re looking at, regardless of the lamp’s light, you should replace the safety switch to avoid further hardware damage to your television.

Uninstall the protective latch of your lamp’s safety switch (the little piece of plastic supporting the lamp’s position) and check if it’s broken.

If you’ve allocated any hardware damage on the safety switch, replace the unit.

Solution #5 Factory Reset The TV

If nothing worked out so far, then your best shot is to perform a factory reset on your Mitsubishi TV.

That would revert all settings to default and hopefully, the red-light issue would be gone and your TV would function normally.

Follow the steps down below to perform a factory reset on your Mitsubishi TV:

  1. Open the front panel by pushing it until you hear a click.
  2. Locate the factory reset pinhole.
  3. Grab a paperclip or an instrument that is thin enough to fit.
  4. Press inward the reset hole and hold it down for 30 seconds.
  5. Wait for the green LED to stop flashing.

Your TV will now reboot and afterward, it should be reset. That should solve the issue.

In case the TV does not want to start and the red light is still there, you might be facing an internal hardware issue.

Thus, to fix a red light on Mitsubishi TV, first hard reset the device and inspect the internal fan. Next, try factory resetting the device and make sure that the lamp door is closed all the way. Finally, check the lamp safety switch and replace it if necessary.
