When a guide shows the wrong local stations, first identify whether it belongs to the antenna input, the device's live-TV area or a separate internet app. Apply the correction to that guide. An antenna rescan will not automatically refresh an IPTV app's program data.
Keep one or two examples of the wrong listing before changing settings so you can see whether the correction worked.
Why am I seeing unfamiliar local channels?
Write down how you reached the screen: the input selected, app opened or menu used. Then compare a familiar station with its official schedule. Is the station wrong, the time wrong or only the description missing?
Those distinctions matter. If you are unsure which source owns the listing, ask support that question first. It is a more useful start than deleting every app or clearing the whole television.
Will changing the ZIP code fix my guide?
For a compatible Roku TV antenna guide, Roku documents the relevant ZIP-code settings and rescanning steps. Check that the location reflects the actual home and follow the instructions for that input.
For a separate streaming app, use its own documented guide controls or contact the service supplying the data. A TV-level location setting may not control that app at all. Keep antenna changes separate from subscription settings, and do not treat removing a channel from a list as cancelling a paid service.
How do I check that the correction stayed?
Choose three familiar entries and record their station names, current programs, next programs and times. Apply one documented correction, then check the same entries. Leave the guide, return to the home screen and reopen it once more.
If the improvement disappears, include that in the support report. Avoid moving the antenna, rescanning and editing location settings together; several simultaneous changes make a temporary improvement hard to explain.
Local reference: Sacramento had 200,321 households in the 2020–2024 Census figures. Use your own location and the guide actually on screen to choose the appropriate settings.
Keep the repaired list easy to use
When the correct entries appear, use supported favorites or filters to shorten the everyday list. Keep similarly named antenna and streaming entries distinguishable. Show the other viewers how to return to the preferred guide from a different input.
Verify playback separately from a correct title: a listing does not confirm a recording or establish access to every displayed program. For an unresolved issue, send support the device, guide name, location setting and the three examples, together with what still works. Remove private account details and full access URLs from any screenshot.
