can anyone throw any light on why the three dials in th pod get a black blotchy effect in them, took em out and apart ad all aia can see is a thick peice of plexi glass which the bulbs shine through, but couldnt see and muck etc ?

 

The dial themselves is in fact Elctro-luminesent sheet. Sadly when they start to degrade they turn black (basically they are burning out)

The only way to get a pure colour again is to change them for either new ones or after market ones
