OS 10.5 appears to be causing an issue with my TV

My Roku Streaming Stick + (Model 3810X) was updated to OS 10.5 and appears to be causing issues with my tv. When launching apps, such as Netflix, my TVs backlight shuts off completely but I can still see the picture (barely) and hear audio. Manually adjusting my TV’s backlight settings will not turn it back on. However, restarting my TV seems to fix the issue - until the backlight shuts off again. The issue seems to be intermittent but it’s still very annoying. My TV is an older Insignia (Model NS-39D400NA14). Has anyone else been having this issue?

I'm not aware of an HDMI CEC command to shut off a backlight, so I'll just take a wild shot in the dark:  By any chance are you powering the Roku via a USB port on the TV?

My Roku was powered by the TV’s USB port. However, I switched to a USB wall adapter. Still having the same problem though.
