Yes. If the battery state of charge is low then the car can disable high current components including the screen heater. Usually after a few minutes running the disabled systems are turned back on so you can try either charging the battery or just running the engine for a while and then check for voltage using a multimeter on the heating filaments. 2008 MY Java Black TDV8 HSE

Thanks for the reply.the battery is at 12v ignition off and charging at 14v or just over.could it be a weak battery?
