Hello,

If your television fails to come on, then you need to check your lamp and the capacitors on your television. Since, the lamps light is coming on, then you need to check the lamp first before you check for bad capacitors.

Turn off your television, then you unplug it for about 6 hours so the high voltage will dissipate because television stores current in it. Then you get the appropriate screwdriver, then you unscrew the back cover open, then you reach for the lamp, turn off the lamp switch before removing the lamp to assess it, and be sure to turn on the switch when you are reassembling the television together.

Once you get the lamp, check to see if it is bad or faulty, then you you replace it if it is faulty, or you try a borrowed lamp in it to see if it will work, if that does not solve the problem, then you assess the main panel and the power panel for anyu bad capacitors, lift off the boards and check for any capacitors that seem swollen, shrink or melted, it is bad, then you get a replacement capacitor and fix it in and solder it to the board. Then you reassemble the television back together, Plug it and power it on, this time the television will come on.

Take care and good luck

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.

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.
