Start with the symptom
A subtitle button does not mean every source contains a subtitle track in your language.
On MAG set-top box, begin with a precise description of when the symptom occurs. Keep one source and one account selected, then change one part of the setup. That makes the result useful to both you and support.
Checks for MAG set-top box
Record the set-top model, firmware and portal or playlist method. Do not substitute a device code from another player. Preserve the authorized portal and device association while testing the connection.
| Part of the setup | Check on MAG set-top box |
|---|---|
| App and installation | Confirm the exact MAG model and firmware, then ask support whether an authorized portal account is supported for it. |
| Controls | Use the supplied remote and portal settings. Keep device identifiers private when requesting activation. |
| Connection | Compare wired networking first when a port is available. Check the device date and network status before entering a portal. |
| Playback | Codec support differs between MAG generations. Ask about a compatible source instead of assuming every 4K feed will play. |
Work through the checks in order
- Open the source’s subtitle menu
Confirm the exact MAG model and firmware, then ask support whether an authorized portal account is supported for it.
- Check whether tracks are listed
Use the supplied remote and portal settings. Keep device identifiers private when requesting activation.
- Choose a listed language
Compare wired networking first when a port is available. Check the device date and network status before entering a portal.
- Compare an on-demand item with known subtitles
Codec support differs between MAG generations. Ask about a compatible source instead of assuming every 4K feed will play.
- Check text size and subtitle offset
A portal, an M3U playlist and an activation-code player are different account methods.
Read the result
| Observed result | Next action |
|---|---|
| No tracks listed | ask about the source edition |
| Track selected but invisible | inspect rendering |
| Subtitles late | inspect offset for that source |
Repeat only the comparison that changed the result. If a setting made no difference, restore it before trying the next step. Keep the source label, approximate time and player version with your notes.
Before making a larger change
A portal, an M3U playlist and an activation-code player are different account methods.
A factory reset, complete account deletion or router-wide change is a much larger action than restarting a player. Keep those actions outside this sequence unless the responsible support team identifies a clear reason and recovery path.
Get the right support
Use WhatsApp support and describe the device, operating system, player version, account method, network type and time zone. Say whether one feed, one title, one group or the whole account is affected.
Keep usernames, passwords, full playlist links, device keys and payment evidence out of public screenshots. If support needs an account identifier, provide it privately through the established conversation. Do not send bank-card numbers in the order or help form.
