Sony ht-zf9 sound issues

[Billboo85]

can anyone help.

My Sony  ht-zf9 soundbar has an issue. After 5 or so minutes the volume doubles in volume, I can use the remote to lower the volume, but it happens repeatedly.

I try to go into settings, but when I attempt to do so, I get a message saying I can't access settings at this time....help please

Hello @Billboo85,

have you tried to reset the soundbar?

Steps are described on page 78 of the manual: https://www.sony.com/electronics/support/res/manuals/4727/d1ff451e44dc39fc895aec29e654d9a6/47275332M...

Hi Billboo85, try the reset as Nic said, there's a reset without he menu. Also, try to leave it unplugged from the mains for few minutes first.. that helps in a lot of cases.
