Sound keeps cutting in and out

Easy fix. No soldering. We have 4 of them. Did not want to fill the landfill. Found the noise coming from the power supply with a scope. Studied the Service Manual. Discovered that they use the exact same power supply in both sound bar and subwoofer. Swapped them. and thing work perfectly with no noise coming from the subwoofer that i can tell. Definitely no noise coming from the sound bar.
A bit more details: I connected my iPhone to the sound bar. Played Spotify with the volume turned all the way down. Static loud and clear on sound bar. On my sound bar, I discovered the static went away after about 15 minutes. I could see it go away with scope. Disconnect power for about 2 minutes and when reattached, static starts again. Static went away again after about 15 minutes.
Disconnect Power FIRST. Get your electric screwdriver and remove a bunch of screws including the screws on the connector panels. The power supply has a large yellow transformer and two silver heat sinks. AC power goes in one end and a single strip connector with a bunch of wires comes out the other. MAKE SURE POWER IS DISCONNECTED!!!! This could kill you if you miss this step. Remove the power supply.
Disconnect power on your subwoofer. Remove the 4 silver screws on the bottom of the subwoofer. There are about 4 black screws with little arrows holding the back panel in place. Remove those. You will only be able to slide the assembly out about 2 inches. Cut the white wire tie on the big foam covered wire. This is the speaker wire and once the wire tie is cut, you can remove the assembly about halfway. You will see a little coil of wire with three wire attached with another white wire tie. (Ferrite core just in case you wanted to know). Cut the wire tie and the entire assembly will come out. Remove the speaker and the three wires from the connectors and the whole assembly slides out.
Swap the power supply with the one from the sound bar. Put it all back together or test it if you want to insure this fixes it.
Enjoy!

Not that it would help.

Is the white noise present in the absence of an input connection, free-floating?

The amps in both of them sound like they

if your speakers are near to some electronic devices you'll get theses static noises try to keep them away from electronic devices which solves it very easily..

Simply unplug the machine for more than one minute. Then plug it back in again. That makes the system reset and the problem went away.
