SOURCE: Lg 32LC2DU-UE lcd tv sound and backlight but no video

Hi barry
To answer your question;
Strange coincidence but i repaired the same tv model that you have yesterday and for the exact same problem so here`s the fix;
In your power supply on the 5volts line there is two 3300mfds/10volts capacitors gone bad and that caused the voltage to drop to 4 volts(not enough to shutdown the set but enough to kill the video)
You`ll recognize these capacitors by a rounded top and some fluid that leaked out, you can replace them with 3300mfds/16volts since the 10 volts variety is harder to find.
And while your at it you should inspect and replace the other capacitors in that area that have the same look
Good luck and keep me posted

SOURCE: Just bought an LG Plasma

The tv is faulty and the fact that it failed immediately after you have started it for the first time is a clear indication of a manufacturing defect.
Take the tv back to the seller and ask for a replacement one or your money back.

A backlight will either not light because of no voltage or no control (not being switched on by the set).

How to fix an lg 47LE5400 tv power lights come on but no picture


If it's a led tv and if you have sound and, also, if you can see the picture with a flashlight very near on the screen in the dark, that means your backlight or your inverter circuit that control the backlight are defect. Good luck,

Hi Angela,
The backlight system of your TV has failed. Mostly it is the inverter part inside the TV which makes necessary power for the backlights fails. The power/inverter board needs to be repaired or replaced.

I have an LG 60 inch plasma model 60PV450 that has no picture but does have sound


It is probably the backlight inverter board. These are common problems on all LCD and Plasma units that use fluorescent backlighting.

No picture


Sounds like you have a backlight problem. To verify this, turn on the set, dim the lights in the room, and shine a bright flashlight on the screen. If you see a faint picture you have a backlight fault. It could be as simple as a bad capacitor in the power supply, or a faulty inverter board, or in rare cases a bad backlamp.
