Re: oil low in red lamp

The substance is a clear antifreeze. The purpose is to keep the phosphors on the CRT cool so it wont burn. If the liquid was low, it means there is a seal or bladder leak somewhere. The tube needs to be removed and the leak can be patched with silicone rubber or the blader needs replacing.( check for cracks). Refill with coolant and re install. Use rubber gloves because the liquid coolant is hazardous to your health.

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.

Blinking red light that says bulb

It means your lamp is burnt out and you have to replace the lamp with a new lamp. When you install the new lamp dont touch the glass lens part at the front of lamp or the oil from your finger will burn the new lamp and it wont work.

LG dlp rear projection Tv model 56DC1D. When switching on the yellow light flashes for about 2 minutes then the red lamp light flashes twice before switching back to standby mode. The TV is approx 18...

First, check if any of the vents are clogged with dust. If not, try another lamp. They don't always look bad when they are bad. If you feel handy, by the lamp itself without the cage and swap in the new lamp. Make sure you do not touch the new lamp (finger oil is bad for the lamp. The oil creates a hot spot and early failure).

Yes. It should show low ohms. If you've never used one before compare the readings to a norman light bulb and they should be similar. Keep in mind that oils from your fingers will shorten the lamps life if it is good. So if you need to replace it hold the lamp with a clean lint free cloth. Good Luck.

red light blinks in 5 times then pause and then repeats. It is the lamp error. " Lamp Driver Defect"
When the "LAMP-PORT" (pin 95) is low, the lamp is not turned on. If the "LAMP-HV-DET"(pin 96) is low at the same time, it is classified as no high voltage of the lamp driver. I'm guessing it needs a Lamp driver which I think is on the C Board, which is part of the "Optics Unit Block Assy. The C Board cannot be orderd separately, and Optics Unit Blocks are not cheap. Good luck
