T2 TV backlight led randomly switching from video to color mode

My T2 LED TV backlight randomly switches from video mode to color mode (usually white). This happens quite unpredictably, sometimes after a few minutes, sometimes after an hour or more. The switch is always from video mode to white color. This also appears to happen when first turning the tv on - it always comes on with the white color mode even if the last status when the the tv was switched off was video mode.

I am using the plug-in via Hoobs Box (most recent version) and the Govee turning on and off is couple to the tv turning on and off via corresponding scenes in HomeKit.

The plug-in is updated to the most recent version - this issues has been happening for at least the last few versions - it didn’t happen initially, but I am not sure what version I was on then.
