Evening all,
I've had my car a month and am trying to iron out the niggles.

Despite me not sitting in the back, it annoys me that the TV's aren't working properly.

The drivers side lights up when you switch it on, but there's no picture.
The passenger side did the same for a few days but now nothing at all happens.
All the functions work on the head unit and the sounds transmits to the wireless headphones as it should.
There are no breaks that I can see in the wiring.

Any advice on what to try next would be appreciated.

My car is a 2006 4.2SC
