I have enjoyed my HT-Z9F since April. In the last week, I have been plagued by frequent episodes when the audio ceases, a loud buzzing sound emanates from the soundbar, and the soundbar then spontaneously restarts. It would then play normally for variable periods and do it again.
I have only noticed this when an Apple TV 4k or Philips 4K blu-ray player are playing—they are connected to the soundbar’s HDMI inputs. I also noticed that after each restart, the HDMI input settings on the soundbar revert from “enhanced” to “standard”. But I’ve also seen a restart with the soundbar set to “standard” also.
I had not made any changes before all this began. The HDMI cables are Monoprice certified.
I have power cycled everything and reset both the TV and soundbar to factory defaults, but the problem continues.
Any suggestions? Thanks.
