So I hit 200,000 ks the other day, but the 2 doesn't display correctly, so I have pulled it apart to try and see if anything is lose, now I can't get it to display anything, not sure if what the 2 pieces of rubber either side of the km screen are for? Maybe they have to go back a particular way? Any ideas?

Now the light won't work, and know the light behind it won't even come on
