LCD info panel on Peugeot 206 broken up

Both the LCD info panel and the mileage counter on my Peugeot 206 has broken up. The car was kept on the side of a mountain and unused for over a year which is what the previous owner said has caused this, suggesting it's damp...? I'm not so sure, it sometimes shows more segments than other times, but generally I guess it's a 'replacement' type scenario?

Any advice appreciated.
