Hi Tinkertoo,
Welcome, and thanks for posting to the Roku Community!
We appreciate you letting us know about using your Roku remote to power off your LG TV.
We want to investigate this issue you're experiencing further. Can you please provide the following information?
- What Roku device are you using right now? (Roku Express, Roku streaming stick, Roku Ultra, Roku streambar, Roku TV-Specify)
- How are you powering your Roku device? Is it directly plugged into the wall outlet or a power strip?
- Have you tried switching HDMI outputs at the back of your TV to see if that fixes the problem?
With detailed information, we will be able to assist you further.
All the best,
Chel
