If you feel brave, this was released on 16 DEC 2018. They still do not know the true cause of the Blank Screens. They are collecting surveys from techs who are working on the cars to try and isolate it. But to try and 'fix' the problem, JLR is telling their techs to:

Reset Procedure:

1) IDMA Reset:
Pull Fuse 1 (15A) from the QUIESCENT CURRENT CONTROL MODULE, located Right Hand rear quarter trim panel
If this resolves the issue please, reset is complete.
If issue is still present continue with step 2

2) IMC Reset:
Pull Fuse 5 (15A) from the QUIESCENT CURRENT CONTROL MODULE, located Right Hand rear quarter trim panel

If issue is still present continue with step 3

3) SICP Reset:
Pull Fuse 15 (15A) from the QUIESCENT CURRENT CONTROL MODULE, located Right Hand rear quarter trim panel
If this resolves the issue please, reset is complete
If issue is still present continue with step 4


4) Quick power mode cycle:

If issue is still present continue with step 5

5) Quick sleep cycle:
