Why does my Audiolab 8000s mute light stay on?


Your amp is probably in Protect Mode, meaning you have DC Offset( a damaged amplifier). That will have to be repaired, before you can switch the unit on. If you need more assistance, or would like to inquire about repairing it, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.

Hi
When you say that you slid your finger back and forth on the strip
do you mean the strip along the back of the laptop just below the screen ??
Because on some laptops the wifi switch and cap locks and the mute switch are all along
that strip

so you may of by accident pushed them all and de activated them all
pressing them all in turn should activated them again but if they done
then you could try FN+ the keys that you want to activate

Alpine pkg-1000


Hello alpine_freak, You can disconnect power from the unit and this will kill the power feed to the system memory (the memory that hold commands from the remote)Now if this does not work I have seen where the unit indicated mute as a response rather than an actuator of an event. This is rare but it does happen. What could cause this is if the audio pre-amp goes out or is turned off by the mute button and there is no sound the unit detects this and indicates a mute. This I hope is not what is happening here, because this is a design flaw, the mute should turn off the pre amp and indicate a mute condition because the mute button was pushed, not indicate mute because of a no-audio condition. As said try to remove power from the unit and if this does not work, I would suggest finding a shop on fixya to take or ship your unit to for repair
