I saw another thread on this forum that exactly matched mine (see here) but it’s been closed so I’m opening a new one.
Every hour or two I get a blackout that lasts a couple of seconds, then the picture comes back but the sound is quiet, then another brief blackout, then the picture comes back.
I’m using a Sonos Beam connected to the TV (Philips 65PML9200, previously a 65OLED856) via HDMI Arc.
I’ve had the Virgin Media (STB) box replaced and Richer Sounds just replaced my entire television after months of arguing with them and Philips (the manufacturer). I’ve now got a new, different model TV and the same fault has occurred. You can’t imagine how angry I was that after all that, it seems like Sonos might be the cause.
Has anybody else had this issue? How can I diagnose?
My Sonos is out of warranty.
