idrive screen completely dark

[brian5]

As previously posted, my screen was dark twice late last year and then dim once this year.

When I took it in to the shop on Jan 27th, I had shown them that it was dim. After restarting the car, the CID was operating normally.

The following is from the shop's notes:
Performed short test with ISTA but no faults for CCC or CID showed up.
Performed test plans for CID background lighting and for CCC malfunction. Both ended without faults except the CCC test plan stated that over or under voltage can cause sporadic failures with the CCC.
Switched over to DIS TESTER and performed further tests. That test still showed the CID as O.K.
PUMA case submitted. R/I center dash vent assy and CID. Found the LVDS cable slightly kinked. Replacement of CID was recommended.

So they replaced the CID and re-programmed the car. I know that they had to wait to get approval from BMW NA for the CID replacement so they had the car for 3 days.

What's interesting is that the screen is brighter than before. I have always had it set to default Brightness (middle setting) and that's where it's set now. Definitely brighter. Not sure if it's sharper too.
