I have an XR-55A80L with a PS5 connected. Everything was OK until yesterday when the PS5 turned on without warning while watching a Disney+ (through the TV app). This caused the TV to switch over to Input 4 (PS5), thus disrupting Disney+ viewing.

The PS5 was in rest mode and this occured a couple of times so I "switched off" the PS5, but it occured a couple of time again.

To stop this happening again, I left the PS5 switched on.

What I have noticed in the last couple of days or so is that when the TV is turned on, a notification is appears on-screen saying that "Ethernet is connected" so wonder if it's related. Both the PS5 and the TV have a wired, Ethernet connection.

I will check if the same occurs if I connect the PS5 wirelessly to determine if it's the TV switching on the PS5 or the network but just wondered if anyone has experience the same issue.

As the update suggests, the PS5 being left on is still an issue. How can the common thing be one device when two devices are involved and, as someone else has suggested, has HDMI control? I've now discounted Ethernet, wired connectivity (wake on LAN sort of issue), and really suspect the TV and HDMI control.

Looks like it might be a Sony support call that's needed. Sony TV with PS5 is not a good look.

Probably a FW glitch.
