Question about Projection Televisions

1 Answer

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 months old and not subject to extended warranty. I looked at the lamp and could not see anything wrong with it.

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).

Hi,
The lamp has already a resistance which is sense by the processor and made the unit a subsequent shutdown. It will produce an overload to the ballast board which is detected by the processor. Replace it with new one and your unit will back to normal again.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

MY philips tv model number 55PL9773/17 WAS TURNING OFF THE SCREEN AND LEAVING THE AUDIO ON FOR ONE MINUTE. THEN THE YELLOW LIGHT STAYED ON. THEN THE LIGHT TURNED OFF. thEN I TURNED ON WITH THE REMOTE AND THE YELLOW LIGHT TURNED ON AND A FEW SECONDS LATER CHANGED TO THE GREEN LIGHT AND THE TV TURNED ON. AFTER A FEW MINUTES, BETWEEN 10 AND 30 IT DID THE SAME THING. NOW IT IS OFF WITH A BLINKING RED LIGHT PERMANENTLY ON. TO TURN IT OFF I HAVE TO UNPLUG IT FROM THE WALL. I REPLACE THE LAMP A FEW WEEKS AGO AND IT IS FINE.

I have an LG DLP. that turns off after 15 -30 seconds


If the second light is blinking to orange or red, that is usually the lamp indicator light on an LG DLP tv. That indicates your bulb needs replaced, or something surrounding the bulb has failed (like the cooling fan for the bulb for example) IF you have a spare bulb handy, I'd replace the bulb, keeping in mind if you touch any part of a new bulb with your bare hands, you just cut the life of the bulb by more then half.
