Mercedes CLK 320 cluster LCD pixelated

[static2y]

Hey all
I recently bought a mercedes convertible CLK 320 (03 plate) but unfortunately the middle dial on the cluster (the one which shows the malfunctions) is scrambled, and just showing a pixelated screen. Pic below. Does anyone know of this issue being a common one, and a way to fix it?

thanks
