Question about LG Televison & Video
Posted by Anonymous on
If you already tested with the flashlight which is the first step in the blank screen with sound fault then you have to test the LED Backlight supply voltages if you are familiar and good in the electronic repair. First you have to check if bulging capacitors for the LED Backlight drive voltage circuit, replace them. If capacitors are good then you have check the backlight LEDs. The flashlight test proves that the power supply is good and TV is working fine because the sound is ok and picture is fine. Attached videos and links may help you for the repair and replacement of backlight LED strips or LEDs itself depending on the type of LED strips used in your model.
