CID not working anymore

I tested my ccc system and everything works. I left it there and went back after a couple of days and the screen won't turn on.
I've got another ccc system and tested that screen and it also doesn't turn on.
When I test the screen in another E90 it works.
There are 4 or 5 wires on the plug which goes on the back of the cid. There is a wire yellow/red. Does this wire receive 12V ? If so I measure 0V.
Maybe a broken fuse.
The car is an E91 pre-lci.

Is your battery good ?

Is your battery good ?
As the IBS System can turn stuff off if the battery is low.
Read the first PDF about the IBS
Try putting a full charge on the battery and see if things come back
to life.

Thank you for your reply.
I fixed it it was a blown fuse. The yellow/red wire should have 12V.
