Minor niggle on console

[Zippyworld]

Hello

I just bought a 2012 Focus zetec as my lads first car.

I noticed that the back lights on the console where the number buttons are, are not lit, but only a couple. Two are off, and two flash intermittently.

Has anyone come across this and found a cure ?

The sync software appears to be up to date according to the Ford website.

Thankyou
