My Logitech Z-5500 have not been able to start. When you press the power button the pod turns on but will only stay on while you hold down the power button while displaying "Input: Direct 96-24, Effect: Detecting...". The second that you release the power button it returns to the idle red ring on the power button. I have tried different power outlets, changing inputs, and putting in new fuses. Any idea what to try?
