The top screen is weird and fuzzy colours are all wrong has a green like at the top of the screen. Bottom screen is smashed, responds to touch. L button doesnt work. Hinge feels loose makes a crack noise when i open/close it. (havnt seen a crack in it) Too much work to repair? Should i just sell it broken? Or Can the top screen/ L button be fixed by opening it up and doing something? and i just use replace the lower screen with a spare of mine?
