Yellow blinking status light

Original lamp died. Bought exact replacement. Placed into position and replaced cover, Now, yellow blinking light. According to manual, 'cover is not placed or lamp cartridge is not seated'. Both seem good. Cover switched was checked ok. Could this be a bad ballast or is new bulb bad?

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.

Wd-60737 mitsubishi blinking yellow status light ?

Mitsubishi TV troubleshooting
Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

If the status led is blinking yellow its indicating that the filter cover on the side is open. If its the lamp indicator thats blinking yellow its indicating the lamp door cover isnt attached properly.

Status Light Problem

Is the status light yellow or red? If it is yellow, then check the dust filter cover. That cover might be off or not secure. If the status light is red and blinking, then try unplugging the TV for a minute. If the error doesn't resolve the TV needs service. If it is out of warranty, you might want to open up the set and look for any obvious problems on the circuit boards (scorch marks, soot, bulging or leaking capacitors (look like cylinders on tripods)).

I hope this helps.

Yellow light keeps blinkingand the tv wont turn on

If the status light is blinking yellow it means the filter cover is open ( On the left side of televison)
If the lamp light is blinking yellow it means the lamp cover door is open. ( Behind front lower panel) If both covers appear intact the switches may be defective or not engaging properly.

Mitsubishi WD-62525 yellow blinking status light

Check that the lamp door is closed all the way. There is a saftey switch that closes from the door being on all the way. If not the status light will keep blinking. There is also a switch on the air filter door.

TV was working earlier, today came home no green power light no nothing

I looked up the manual online - after you replace the bulb, you need to reset the bulb life timer. Using the TV remote push the menu button, SETUP menu, select the lamp reminder option to reset the hours to zero. That might help the status indicators.
