all speakers started power cycling on friday the 7th

[Brandi72]

Yesterday we noticed that our soundbar downstairs was power cycling and would not stop and when I came upstairs the one up there was doing the same thing.  I managed to rest them and they are working but now my 360 R7 speakers are doing it too and I can't get them to reset.  Anyone know what to do?  All the speakers were Samsung.  Does anyone know if they did some sort of update yesterday?

If these videos are supposed to be answering my HW-K950 issue, how do I get them to play? I get some message about not having sufficient “privileges”.

They are not really videos but are links to what others have posted or replied to address the problem.
