    My TV turns on, makes some noise for about a minute then turns off again. There is no activity on the lamp indicator, or on the temperature indicator

Hi,

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.

Please help


That is the blink code for the lamp ballast. Here is the more complicated explanation from the service manual.

IC2301(pin11) detects the error of LCD Power C.B.A. and Lamp,
then indicates the error when an inner malfunction of LCD Power
C.B.A. occurs, the Lamp voltage becomes more than 130V or
less than 30V, Lamp current becomes more than 5A, or the Lamp is blown

Hope this helps.

Hitachi 55VG825 rear proj television blinking light and screen doesn't light up


Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...

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.
