I've got a Necvox 7169 indash motorized screen witht he DA-230 I control box, which controls the screen.

It was working all fine, just suddenly the screen display froze!

Haven't been able to get it working since
Im pretty certain is the control box which isn't working as the screen will open when its disconnected from the control box.
When i connect the screen to the control box, it just wont open!

Can anyone give me ANY help with this? my mates looking at the circuit board but he can't find anything wrong with it
