Picture blinks in and off for a few seconds then goes kind of pink and then the remote does not work

Picture blinks On and off for approx 10 seconds, then comes back on for a while, then picture goes kind of pink but carries on playing. The remote at this point will not control anything and the sound goes off. I have to reset the box and then it's okay for a while then the above symptoms repeat in typically half an hour
