I have a LG 47LN5750. No picture, sound yes, I see menu when using the flashlight test and have no back lights showing. please help with my next steps in fixing this issue. Just happened this morning.


What you are describing is common in these sets. The power unit tends to cause the LED backlights to fail. It is a 50 dollar parts cost but you have to upgrade the firmware to prevent it from happening again
