I have the Nu Pogodi IM-2 here, but apparently some (battery?) fluid got inside the LCD, rendering the left side semi-useless. Maybe someone more knowledgeable can salvage it?
The type of damage shown indicates the lcd glass itself is cracked, and the black stuff is the lcd material itself leaking or oxidizing due to air or moisture getting in through the crack, or some similar process. It is not fixable.
