Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.That problem may, possibly, be owing to the DEH device suffering either an electronics failure that affects the controls, or else owing to a 'dependency' on another device being shut Off too.So try turning Off all other devices in the stack or console, first. Then try turning it Off again, when it's the last device that *can* turn Off, in the stack or console.
