Yep - Either corrosion on the LVDS connector or a damaged internal display

At this point you’ll need to check your logic board displays connection. The LVDS connection may have corrosion damage and/or the cable is damaged or the display its self.

I would also try an external display to see what it shows.

Follow this guide MacBook Air Models A1237 and A1304 Display Assembly Replacement to Step 3 then jump to Step 23 disconnecting the cable and inspecting the connectors for damage.

Given the age of this system it maybe time to upgrade to a newer system (used or new).
