Has anyone run into boot up late-2013 15” mbPro with no backlight but external monitor works? what’d you do and cost to fix it? I’d like to know, thanks….( something to do with VCore chip, based on my search)

if you disconnected one end connector of that cable(like pic.#3), it won’t charge and doesn’t show battery under system report….well, that what happened to me late 2016 mbp 13” non-touchbar

yes, I replaced lcd on my air 2013 13" with lcd 2010 13" and it works.
