dial display disappeared!

[startrack]

Hi newbie to this site and have just tried to mod my dials with chrome inserts which has proved more of a headache than has been put up on the site. firstly i could not for love nor money part the backing of the dials with the front plate to get to the actual dials themselves i followed the thread clearly but if you check the mod is not a x5 dial cluster so kind of doesnt count. when i abandoned this and placed me display back in the housing and connected the 3 plugs back on all i get is the parking handbrake light on nothing else can anybody help i now have no digital display!. I have a 2001 x5 3.0i rhd thanks
