Is there a universal remote that will work with a Harman Kardon AVR 154 receiver, including navigating the on-screen display setup menus for configuring the receiver sources and speakers?

$16 for a replacement remote. Generally any device the comes with a remote needs one.

It may be on Mute, or it is broken. Or you didn't connect speakers, or the signal is going to the wrong speaker output.

Hope this helps as some older parts are getting scarce!

Its asking your permission to unlock the setup menu. When you hit setup, and it says "unlock," you have to hit one of the navigation arrows on the remote control. Once you have unlocked the menu, you can assign the audio to that HDMI input.

It will only display via component. Your HDMI firmware is either 1.1 or 1.2 and has HDCP issues (High Definition Copyright Protection) it's a firmware problem that has been fixed on all new receivers, not just a HK issue, all receivers! the new version 1.3a and 1.3b have fixed the issue. Unfortunately you cannot update the firmware on the receiver. Hope this explains it for you, sorry! Lot's of angry people out there!!! myself included.

Do you have your receiver output connected to the input on your TV? For example, if the receiver is in connection number 1, is your TV set to connection 1?
