If there is no power at all, such as no lights at all. Then it has probably had an internal fuse failure, or something has gone in the power supply of the unit.
Power on the Harmon Kardon by pressing and holding the power button until it beeps.
then, press and hold the Bluetooth button (on H.K. Speaker) until it beeps.
Make the Samsung UN46EH5300 Bluetooth to be VISIBLE.
The H.K. will emit an audible when successfully paired.
Try setting up speakers through your TV. (I suppose your Tv is wifi in to tv) Tap menu on tv remote. Go to network. Tap wifi, then follow TV's direction.
it could just be a result from the streaming service itself buffering on your network so if the audio and video are not in sync while streaming try rebooting the streaming service and disconnecting and reconnecting the network. If its the TV itself that may have the problem then its an issue with the image processing and a quick fix to that is to set your TV into game mode.
Either track down the original remote for the model, or get a universal one, try and get the type that searches for the code automaticly otherwise you will be hunting around for the remote code that is correct for it.
Look at the graphics equalizer settings to see if you have selected large hall, large room or any other setting that is available. Then turn that setting off.
If you are talking about the driver cones in each of the units, then it's odd that they should have gone, unless they have driven too hard or damaged (say by a child poking them). Double unit speakers have a crossover built into that separates the sound into treble and midrange or bass.
If the sound coming out is "treble" the high frequency that shows the bass units are not working.
Make certain all the wiring is good to the speakers and if you can see the bass speaker check it is not damaged.
If you need to, go inside the units and connect a 1.5 battery across each speaker terminal for a second. If it "pops" then it's working.
That shows the unit is switching them off somewhere. Perhaps on different modes or surround settings.
If you have a DVD marked THX that will have testing settings for the system. Then you will be able to found out if a setting on the amp is responsible for the loss of channels.
