s4 headunit problems

    Hi. My concert stereo is misbehaving. Sometimes when I turn the engine on, even though the stereo is powered up, all I get is the backlight. If I turn the car off, lock it and leave it for at least 1 hour, it seems to come on again normally when I start the car.

    Any ideas as to what might be wrong? Seems strange as I get lights and the units clicks when you turn it on, but nothing else. Happens twice to 3 times a week at the moment but is becoming more frequent.

    Thanks for any advice
