K70 - X key missing full rgb

[Hexagon]

Hi guys, I own the k70 for 4-5 years now. Recently I noticed X key only produces green blue and yellow colours. Whenever I had it set up to light up on press it also randomly lights up 6 different keys green for some reason. Updated ice, reflashed firmware to no avail. Question is, anybody here attempted a repair? I know I have to destroy the logo to get to the key which is a shame but if it's a matter of re soldering the contact or cleaning it up I'm up for it. Just wanted some more information if that is even fixable in theory.

PS. No liquid was ever spilled on the keyboard so there is 100% no liquid damage to any of the keys.
