Could a faulty LVDS cable cause no backlight?
I've recently replaced my laptop logic board as there was a number of issues with the early 2015 MacBook like keyboard backlight not working and fans running full speed, but the main reason being the backlight not working. I can see the LCD working when I shine a flashlight through it and works with an external display.
After logic board replacement, the laptop nearly works fine except for the display backlight.
Could a faulty LVDS cable be a possible issue?

After disconnecting the battery, disconnect the display cable (its not LVDS in the retinas - now using eDP/iDP signaling, just call it what it is). Take a picture of the cable end so we can see the gold contacts and post it here for us to see Adding images to an existing question
