Can you post a screenshot of the ads?
Thinking you may be in Store/Demo mode rather than Home Mode and these aren't ads, but banner overlays for this Samsung TV.
For most Samsung TVs, use the Samsung remote (not Roku remote) and go to Settings/General. Then select System Manager/Usage Mode. Set to Home Mode. (If a pin is requested, try using 0000).
