Thanks for the post.
Is this issue happening only on the Youtube channel or does it happen regardless the channel you are watching?
Have you tried unplugging your TV for 5-10 minutes, then plugging it back in again to see if you are still seeing the issue occur?
Please keep us posted and we will be able to assist you further.
Thanks,
Danny
