There are many issues that can cause this. It could be a Power Supply, Amplifier, or scores of other issues. All these units have a microprocessor(computer inside the Bose unit) and are generally controlled with a Rotary Encoder( basically a volume control), or buttons. There are just too many problems that can cause this same issue; dead or won't switch or with indicators blinking.
