Question about LG Televison & Video

1 Answer

How can I tell if I need a new LED driver board or an actual light for my LG 32LB560B? No Backlights peeping through the holes in the back. I see something when I use the "flashlight test." THANKS!

I still have sound, but nothing comes up on the screen unless I flash a light on it with the room lights off. To a layman, this looks like I need a "new bulb" because it's "burned out." But online, it looks like I might need an LED Driver board. Is that, the driver board, the more likely scenario? THANKS! ***Edit*** Interestingly enough, not only does it "pass" the "flashlight test," You can actually see a faint image--an image with enough contrast, even when there's no flashlight shining on it. Now I'm even more confused. My one answerer says it's probably the lights strip--we shall see!

LED screen is black, but my tv still gets sound. LG told me this would be $331 for them to fix since the TV isn't under warranty. Could it be as simple a fix as the T-Con board?

Audio is fine. Why did picture suddenly go black?


The board that controls the back light for the screen is called an inverter board. Sometimes, depending on the model , the inverter is combined with the power supply board. Go here to find the parts :www.shopjimmy.com

I have a LG LED television that has no picture but does have sound. I have narrowed the problem down to 3 circuit boards. I'm trying to find out which one is faulty.

If the power supply board is working then it is back light problem, first do a flash light test.
