Locate the source that draws the text
Determine whether the programme runs in a native TV app, a connected set-top box or another HDMI device. Samsung explicitly notes that some sources use their own caption settings. A television preference can therefore remain enabled while that source displays no text.
Use one exact programme and edition that is known to offer the needed track. Caption availability varies; a menu preference cannot generate a missing track.
Inspect the player first for external playback
Open the connected player's audio or subtitle controls using its supported remote workflow. Record the offered track names and the selected one. If captions appear there, test the player's style controls where supplied.
Do not change the television font repeatedly when the external box is rendering the text. The TV receives the completed picture and may not have a separate caption layer to restyle.
Use TV controls where applicable
On supported Samsung software, inspect Accessibility and Caption Settings. Available controls and paths differ by model and version. Check a source the TV documentation identifies as supported before concluding that the system preference has failed.
A broadcast caption, an app subtitle and burned-in picture text are not interchangeable. Burned-in text remains visible even when selectable captions are off because it is part of the video image.
Report availability and styling separately
Record whether the track is absent, offered but silent, visible with the wrong style, or mistimed. Each is a distinct failure. Use a familiar passage and keep the same source and edition throughout the comparison.
Provide the TV model, external device if present, app version, item and track label. No credentials are required to describe the control path. This documentation-based guide does not establish a caption inventory for IPTV Canada or certify any player's accessibility implementation.
Use a visual boundary test
If text remains visible while the external player's selectable captions are off, compare whether it is burned into the source image or drawn by another device. Do not assume an unavailable TV caption switch will remove it. Record which control changes which text. With two active text layers, a viewer may see duplicate lines that require identifying the renderer rather than changing font size.
Sources and scope
Scope notes distinguish published documentation, supplied information and editorial methods. They do not report a hands-on service test.
