My 73" mitsubishi dlp WD-73827 turns off and has a red status light blinking. I have replaced the bulb and the heat sensor... any answer to what else could be the problem?
It is helpful to have the sequence of the blinking red light. This may help:
MODELS: WD-52627 / 52628 / 62627 / 62628 / 62827 / 62927 / 73727 / 73827 / 73927
3. Error Code Operational Check
Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to "12" No Error.
Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occured since the last Initalization.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: If the Error Code is "23", the LED will flash two times, pause, and then flash three times.
