I need help please. The LCD odometer on my mk1 freelander has what looks like a black splodge a cross it, preventing me from seeing the numbers. Is this fixable, and if so can I do it myself?[emoji17]

I have just inherited a freelander mk1 (2001) and for some reason the LCD odometer is almost entirely black. I can just make out the last digit on the right! It's almost like the LCD has bled over the screen. Can I fix this myself and if so how?
