TV randomly turns on-RPi 4, Samsung NU8000 TV, Leia 9.2.5

Every several days the TV randomly turns on. Today it turned on while sitting in the room-so I can't blame the cat jumping on the remote. Everything works perfectly except this.

RPi 4 4 GB connected to Samsung HDMI port, record on network Synology DS718+, boot from USB attached 256GB SSD, OTA from networked HDHomeRun HDHR5-4US only one add-on "HDHomeRun DVR PVR Client", using stock Samsung TV remote and CEC. The problem has also occurred with past LibreELEC versions. Crash crash_dmesg.zip and dmesg logs attached. Thank you.

TomHardy1975 do you use your TV remote to control your pi?

Yes, the Pi is getting commands via TV CEC.

TomHardy1975 if you dont need the CEC you can disable it in the config... that might prevent your tv remote from turning on your RP

use a computer to edit the config.txt file or if you have ssh set up on your RP you can use the below to mount and edit the file. try that and see if it solves your issue.

mount -o remount,rw /flash

cd /flash

vi confg.txt

NOTE: in vi to edit you use the "i" key then you can edit then use "esc" to exit edit mode and then ":wq" to save and exit. or use the text editor you are used to using.

# Force HDMI even if unplugged or powered off

hdmi_force_hotplug=0

# Doesn't sent initial active source message.

# Avoids bringing CEC (enabled TV) out of standby and channel switch when
