Vauxhall Combo B/Corsa C LCD Clock/Radio Display Stopped Working for no reason ... It worked fine until one day I was messing around checking things and changing fuses, it wasn't until that night i realised the display wasn't working.. I tried checking all the fuses , i even tried putting new fuses in where there were spaces in the fuse box but no joy , i asked a friend who is Vauxhall through & through (he's only had Vauxhalls all the time I've known him) , he told me to replace the display unit , i did this but i bought a second hand one that i seen working before i removed it, i stuck it in mine & no prizes for guessing the next bit , CORRECT it didn't work/light up....

Thanks in advance for any help
