Keyboard backlight defective after spoiling liquid
Yes... I spoiled some beer on the trackpad. Keyboard and trackpad are working fine but the lights under the keyboard are not. Just one row in the middle is working.
Should I replace the whole keyboard or is it something else?
There's no way to tell what's damaged. I would take the top case off and clean any residue found as it will corrode parts. Here's the keyboard part: MMacBook Pro 15" (Model A1226) Keyboard
