Green orange then red flashing 3 times light

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

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.

I have a LG RU-44SZ61D DLP TV and recently replaced the bulb. After about two months the TV went really dim and then started shutting off. The problem increased to the point where you couldnt have the tv...

DLPs have flow chart trouble shooting techniques to pinpoint exactly why your set isnt completeing the boot sequence. If you would like the service manual for your model let me know and i will post a link where you can purchase a complete one.

Lamp indicator blinks red

There is a problem with the lamp or around it? When it turns Orange, the lamp is at or near the end of it's life & needs replacing. What does the temperature indicator show? Orange, Red or Red Flashing? If not, then there is probably accumulated dust around lamp area

No picture-lg ru-52sz51d

Depending on what light is flashing it could be a few things. If the Lamp light (the middle one) is flashing that is problem with or around the lamp. That orange or amber light is an indication that the lamp is reaching the end of its life

If it is the Temperature light (the far right one) then the TV is shutting down because it is over heating and you need to check the cooling fan.

Won't turn on.. Operation indicator is red, Lamp indicator is flashing red??

According to the E44W48LCD service manual, the temperature indicator red light states the projection TV shut down due to overheating. Red (flashing) states the projection TV shut down, check the cooling fan.
