Audio and video use separate formats, so a player may decode the sound while failing to display that source’s video format.

Why this happens
A stream is not one indivisible format. Its audio can be playable even when the video codec, profile, level or output path does not work in the installed player. This explains why a source may produce sound and a black image while another source plays normally. A filename ending in MP4 or a channel label saying 4K is not enough to identify all those details. Device support also varies by operating system and hardware, especially outside the handheld platform covered by a generic format table.
Compare a working source and the silent-picture source in the same player, and use its stream-information view if available. Keep codec information separate from an assumption that the account has expired. If the player documents an alternative decoder, one reversible comparison can be useful; randomly disabling hardware acceleration on every device is not. The result to keep is the combination of video format, app version and device model. An alternative source with a supported format may be the practical viewing option while the original path is investigated.
A useful way to work through it
Confirm that sound is really coming from the selected source, not a background session.
Record the video format exposed by the player and compare a working source.
Use only a supported decoder option or compatible source alternative.
