keyboard backlight stop working, already tested led's found no problem

my keyboard backlight just stop working, i have already tested the individual led's that supposed to light up the keyboard with the help of a multi tester and found no problem with them. also check the connectors that run through the logic board and found nothing. any help with this? i don't consider buying an upper case or top case which houses the keyboard. because on my own diagnosis i think that there might be some lose ends within the logic board connector. did someone had ever encounter this problem before? please help.

thanks and regards

Verify that the ambient light sensor which is located aside the camera, or its cable connector are in good shape as well.

The ambient light sensor measures the amount of light near your display to set the amount of light on your keyboard.

The more light near the display, the less from your keyboard and viceversa.

Well if you think that there might be some lose ends within the logic board connector there very well could be - in which case you have to repair the connector or the logic board, depending upon which side the lose end is. You might just be able to replace the ribbon cable if repairing the connector is not an option.
