Lamp is burned out or makes a popping sound.
When the lamp reaches its end of life, it may burn out and may make a loud popping sound.
If this occurs, the projector does not turn back on. To replace the lamp, see on page 38.

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.

TV shuts itself off after a couple minutes of being on.


One must be very careful of the quality of the replacement lamp. Many of the cheap 'deals' on the web for replacement lamps are substandard. I always recommend that replacement bulbs be the original manufacturers bulb.

PROBLEM WITH SAMSUNG DLP TV


It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire
