Question about LG 47LC7DF 47 in. LCD HDTV

1 Answer

LG 47" LCD FLAT SCREEN

AFTER ABOUT 2 HOURS TV SCREEN GOES DARK SOUND OK AND POWER LITE IS ON. IF YOU TURN TV OFF AND RIGHT BACK ON TV WORKS ABOUT 30 MINUTES THEN GOES BLACK. AGAIN. IF IT WASNT DIGITAL HD I WOULD HAVE SUSPECTED HIGH VOLTAGE POWER SUPPLY BUT THAT DOES NOT EXIST HERE. IF YOU LEAVE TV ON AFTER IT GOES BLACK IT COMES BACK ON IN ABOUT 10 MINUTES THEN GOES BLACK AGAIN IN THIRTY. IF YOU LEAVE IT OFF FOR A COUPLE HOURS IT WILL PLAY LONGER. I WAS TOLD IT WAS THE PANEL AND THAT IT WILL COST 5000.OO DOLLARS TO FIX. I HAVE ONLY HAD IT 5 MONTHS. NO WARRENTY

    Other than this problem, it works fine. If it can't be fixed easily, I will sell it, as I am sick and tired of having to turn it off and on.

Well, not completely true; the fluorescent backlight is still a high voltage device, even if only hundreds of volts instead of kilovolts, and either the lamp(s) or the power supply for it (them) is causing the dropout of your picture. When it does it next time, look at the screen from various angles, I think you will see that video content is still there.

LG LCD TV - Buzzing Sound and Faint Horizontal Lines


From your description, the sound you are hearing is the inverter(s) that drive the back light for the LCD screen/module.
The inverters mounted on the back side (one lower right and one left side) of the LCD screen/module. They are under the sheet metal cover/shields.
The inverters are going out and or the LCD screen/module is going bad too.
That LG TV has only a 1 year on parts and labor from the date of purchase, but you could call LG and ask for their help for such a new TV. They might do it under a warranty, for little or no cost to you.
I hope this information has helped you.
Good Luck.

LG 47LC7DF LCD TV turns off with a pop then turns back on.


Sounds like a overheating issue. Try facing a large fan blowing across the back of the unit and see if this changes anything. If it does, it might help to blow the back out with compressed air as dust might be helping it overheat.
