Mitsubishi Carisma

I assume it is known by a different model name by you guys but I have just aquired one and am looking for some advice as to some minor repairs, primerily the lighting failure of the centre dash top display unit, it still functions but is only visible in daylight as the lighting function has failed. I can not see how to get at the rear to see if it can be re-iluminated, either by connection failure, bulb failure or whatever.

Cheers.
