Customer Question

error code 21

Expert:  Aric replied 10 months ago.
Hello and thank you for the question.

What is the model number off of the back of the TV please?

What are the symptoms you're having with the set?
Customer: replied 10 months ago.

WD-73835


TV fan(s) kick on at power up for few seconds three times then everything turns off. Error code indicates 21

Expert:  Aric replied 10 months ago.
Thanks for the reply. I saw the error code. When the sets shuts down, before you press the Input and Menu buttons, does the Timer light blink on the set?

Also, when is the last time you replaced your Lamp?
Customer: replied 10 months ago.


No blinking. Lamp has never been replaced. worked fine yesterday.

Expert:  Aric replied 10 months ago.
Okay. When the set shuts down, does the sound continue, or does the lamp LED light up red?


Lastly, are you certain it's a 2-1 code, and not a 1-2 code?
Customer: replied 10 months ago.

No sound and no picture and never a red light. just unplugged set (blue led side lamps show for a moment) and plugged back in. after fan cycles, i pressed input and menu button for 5 sec and now get error a repeated flashing 6 blinks ontimer light

Expert:  Aric replied 10 months ago.
Okay, I need some more specifics.


How long have you owned the set for?

Also, when you press power after the Fans, do you hear a slight click and buzz sound? Does this process repeat a few times before it shuts down?

Additionally, try that code retrieval ONE more time, and let me know if it's still 6-6.
Customer: replied 10 months ago.

owned for 3 or 4 yrs


 


just hit power button, one click as normal for tv to start, blue side leds light up and fans start for maybe 10 seconds (like they're running but no buzzing ) and then off threes times. This time red LED light show up. Pressed menu and input and still get 6 flashing lights - pause and 6 flashing lights

Expert:  Aric replied 10 months ago.

You need to replace your Lamp. The 6-6 code indicates "Lamp not installed", "Lamp did not fire", or "Ballast did not fire". The set attempts to start up three times, then the Red LED (Lamp light) shows up. This is all common with a failed lamp. These lamps run hot and typically run between 2-3 years and are consumable components that are designed to fail. The solution is to replace the Lamp in your set with the correct OEM lamp. Try to refrain from buying the $40-$50 lamps on Amazon or from Pureglare as they are NOT rated by Mitsubishi for these sets, and tend to run for a few months at most if they even work out of the box. The link below is to the correct Lamp for your set:

ok just ordered from site you suggested. odd course of error code changes. hope this works. lamp doesnt look burnt but manufacure date was 2008

Expert:  Aric replied 10 months ago.

The lamps typically won't look any different when they are bad, as they are gas charged and can lose their internal gases.
