A tvg-logo value points a compatible player toward an image associated with an entry. It does not supply the programme itself. A missing logo can therefore coexist with working playback and correct guide listings, while an attractive logo can appear beside an entry that does not open.
Start by separating the three observations: the image displayed, the programme guide shown and the source opened. Treating them as one success or failure makes troubleshooting harder. A catalogue may use independent addresses for all three.

Establish which picture should appear
A broadcaster can have current, regional and historical marks. If the wrong image appears, compare the intended edition with the actual linked image before clearing application data. A perfectly retrieved image can still be the wrong artwork for that entry.
Logo addresses can also change while an application retains a previously downloaded copy. The old picture is not proof that the playlist failed to refresh. Check whether the current metadata points to the corrected resource, then investigate the image cache through the player’s documented controls.
Diagnose the image path separately
A broken remote image should not be replaced with an unrelated familiar mark just to fill an empty tile. That can make a catalogue look finished while misidentifying the feed. A plain readable name is more useful than confident but inaccurate branding.
- Identify the affected entry and the expected broadcaster edition.
- Inspect only its logo attribute, keeping private source URLs out of the report.
- Check whether the referenced resource is an actual supported image rather than a webpage.
- Review the application’s logo cache or refresh option.
- Compare the result with another entry that uses the same image source arrangement.
Be careful with private image links
An image URL is not automatically public. Some catalogues can contain account-bearing paths or query parameters even in auxiliary resources. Review the actual value before posting it to a public issue, testing it in a shared browser or sending the entire playlist to an online editor.
Locally hosted artwork can improve personal organization when the player supports it, but moving that file can break the stored path. A backup that includes the playlist without the referenced images may restore entries with missing marks. Document whether artwork is embedded, remote or kept in a separate local folder.
For a correction request, name the entry, describe the expected edition and say whether the current logo is missing, outdated or simply wrong. These are different faults. Once the right image is displayed, keep the conclusion proportionate: you have corrected catalogue artwork, not verified the service’s entitlement, playback quality or broadcaster affiliation.
Useful answers
Does a missing logo mean the channel cannot play?
No. Artwork retrieval and programme playback are separate observations.
Will refreshing the playlist always replace a cached picture?
Not necessarily. The player can maintain an independent image cache.
Can a logo URL contain private account details?
Yes. Review the actual address before sharing it.
