Hello everyone I recently purchased my range rover sport autobiography it took me ages to find the right one as I wanted it to have rear entertainment to keep the kids happy for journeys, but I have a slight roblem after driving for about 30mins + and the kids have been watching a tv,dvd etc the picture goes off and the screens go blank (black) The screens will not come back on until I have turned the car off for 10mins or so. When the picture goes the sound still comes through. If I change the source from tv to dvd there still is no picture just blank. The screens are factory fitted, I wonder if anyone has experienced this or has heard of this problem? any help and advice will appreciated.

Kind regards
Aaron.
