Watch the stage boundary
Infomir's Linux/WebKit documentation distinguishes startup output from the configured working mode. A logo appearing and a later blank screen therefore provide two different observations.
Record whether the change happens before portal selection, while the portal loads or only when programme video starts. These stages help support identify the relevant setting or source.
Do not infer a universal hardware failure
A visible startup image proves that one state reached the display. It does not establish acceptance of the later resolution, refresh or range combination. Conversely, losing picture later does not by itself prove the cable is defective.
Record the TV input and any receiver or switch. The complete output route matters.
Use the exact model instructions
Infomir's documentation contains distinct older-model bootloader and newer recovery procedures. Do not apply a red-button sequence or menu path simply because another MAG model uses it.
Consult the actual device/operator recovery guidance and retain a known working configuration. Avoid repeated blind setting changes when the display cannot show confirmation.
Keep portal and signal findings separate
If the portal interface remains visible but one programme is black, the symptom differs from losing the complete output after startup. If the whole interface disappears at the working-mode transition, describe that exact event.
Changing service credentials is unlikely to clarify an output mode the television cannot display, while a working menu alone does not certify programme decoding.
Make the report reproducible
Include model, software image, configured output where known, and the last visible screen. A short factual sequence is more useful than the receiver does not work.
No MAG receiver was tested here. This explanation follows the documented startup/working-mode distinction and does not diagnose a particular portal or prescribe an unsupported recovery action.
Keep sound in the sequence
Note whether audio continues after the picture disappears and whether the television shows a no-signal indication. Those are different observations from a black programme image within an otherwise visible portal. They do not conclusively identify the fault, but help support distinguish an output transition from a video-only playback issue. Avoid repeated power cycling merely to collect the same logo when the critical evidence is the later stage.
Sources and scope
Scope notes distinguish published documentation, supplied information and editorial methods. They do not report a hands-on service test.
- Infomir video output versus graphics resolution — Official article sections inspected: working output and graphics layer differ from boot stage; old-model recovery sequences are not generalised.
- Infomir Linux/WebKit system settings — Official current excerpt: embedded/external portal entry routes and distinct restart/reboot/reset items; operator images may differ.
