Frequently asked questions MAG4xx

  STB does not turn on, external portal does not load, embedded portal is blocked
  After turning power on (not to be confused with STB activation from Remote Control), STB does not turn on or there is no screen image
  • No power supply at Set-Top Box or TV or one of the devices (STB or TV) does not work properly.
    • Make sure that LED on STB is lit.
    • Make sure that both devices (STB and TV) are connected to power supply.
  • STB power supply unit is not working properly or has not suitable parameters (in this case, STB LED can be lit):
    • Check power supply for parameters specified in STB user manual. If necessary, replace power supply.
  • Problems with the interface video cable (HDMI, RCA):
    • Make sure that the cable is securely connected on both sides (TV and STB);
    • Ensure that cable is in good condition;
    • On TV: сheck socket (HDMI / RCA) to which the cable is pluged and make sure that the setting of source is correct.
  After turning on STB from Remote Control, Set-Top Box does not turn on or there is no picture on TV screen
  • Deactivating STB from Remote Control will put STB in standby mode. Current mode (Active/Standby) of STB is determined by color of LED indicator:
    • MAG4xx as default: Red color - standby mode, white color - operating mode (brightness level of LED indicator can be changed - see Settings / Interface)
    • If Remote Control can not bring the STB out of standby mode, restart STB.
  • Probably, Remote Control is not working properly or signal does not arrive to STB's IR receiver - make sure RC is operative:
    • in operating state STB should react to pressing RC buttons (STB LED should blink when RC button is pressed);
    • direct RC right to front panel of STB, remove objects or devices that prevent remote signal spreading;
    • make sure that power supply of RC (batteries) is working.
  STB does not load after failed software update, any STB settings, or resetting
  • Reboot STB;
  • In System Recovery menu:
    • switch Boot mode to alternate NAND;
    • reset to default settings;
  • Try to recover with service button (use sequently each boot mode):
    • Mode 1. Selecting alternative NAND
    • Mode 2. Reset to factory settings
    • Mode 3. Emergency startup
  Portal does not load. Blocking access to portal from Operator
  • If initial boot takes place (logotype and messages 'Loading ...' are visible on the screen), but external portal does not load, reasons can be as following:
    • check network connection;
    • if in 'Portal selection' window the message "Page Loading Error" is brought up - check network connection and URL of portal;
    • IPTV provider's portal is not accessed (blocked access to service from IPTV provider, etc.).
  • If network connection is normal but portal does not load then restart STB.
  • If connection to network is normal but network services are not available then contact IPTV operator.
  • Blocking access to services by IPTV operator (messages such as 'STB is blocked', etc.) - carefully read Info message on TV screen, contact operator or repair indicated problem by yourself, restart STB.
  Network connection troubles

If it possible, check for network (Internet) connection on other home devices (computer, smartphone, etc.):

If STB has wired connection:

Make sure that LED indicator on STB's Ethernet socket is lit. The status of link must be Up (see Network / Wired (Ethernet) / Network info). If LED is not lit and (or) status of link is Down - it means that STB disconnected from the network.

Possible reasons of disconnection:

  • Network cable is damaged or connectors are not inserted or inserted not sufficiently tightly on both sides;
  • Network device on user side (like switch, router) is defective or incorrectly configured;
  • Network device on provider side is defective, incorrectly configured or programmatically disconnection on opposite network connection side;
  • If autoconfiguration (DHCP) is used, the correct values must be assigned for the parameters IP address, Network mask, Gateway (see Network / Wired (Ethernet) / Network info). If these parameters are not assigned, you need to find out and eliminate the cause of the autoconfiguration error (restart STB, check network device (router) settings and (or) contact network service provider);
  • If manual settings are used check correctness of corresponding access parameters (IP address, Network mask, Gateway).

If you have wireless WiFi connection:

- In status window link must be "UP" (Network / Wireless (Wi-Fi) / Network info). If status of link is "Down", there is no connection to Wi-Fi access point:

  • If STB does not detect external WiFi adapter (when connecting adapter to STB appropriate message is displayed), make sure module is working (on other device), and also in module compatibility with this type of set-top box - see Wireless Wi-Fi access.
  • If STB does not detect wireless network, check if the wireless network is detected by other devices (for example, by smartphone). Perhaps, it is necessary to solve access problem on side of the desired network (WiFi access point).

- If wireless network is detected, but you can not connect to network:

  • If possible, check whether STB is able to connect to another access point (to another WiFi-device);
  • Re-enter access password;
  • Check that Authentication Mode, Encryption parameters on both sides of the connection (STB and at Wi-Fi access point) are the same.
  • Delete (forget) the wireless network from STB list and refind/reconnect. Password value is stored in User data (to remove the password - System settings / Clear user data).

- If autoconfiguration (DHCP) option is used then correct values of network parameters must be assigned in STB (IP address, Network mask, Gateway, DNS server) - see Network info:

  • If parameters are not set, you need to eliminate the cause of failed autoconfigurating (restart STB, check network device configuration and (or) contact Service Provider).
  • In case of manual settings check correctness of STB access parameters (IP address, Network mask, Gateway, DNS server) and network device configuration.
  Access to embedded portal is blocked ('Unlock' window is displayed):
If you've forgotten the password of Access control - Reset STB to factory settings with service button (boot mode #2).
  Reboot STB
  • The first way is to turn the STB power off /on (unplug / plug power supply)
  • The second way is to reboot STB by command from System Settings menu
  Emergency recovery of STB operation
  Audio issues troubleshooting

If during video play back in Embedded portal you face audio performance degradation (or complete lack of sound), follow the next steps:

1. Verify that STB perceive commands from Remote Control. When you press Vol-, Vol + buttons, volume control indicator is displayed on the screen, indicating the current volume level. Set to STB the maximum sound level (100%) - Do not change this setting until the issue is solved.

2. Find out if the issue related to certain network resource or caused by audio playback device. Try play back other IPTV channels and video files located on USB-drive or on local network resources (with access via SAMBA / NFS / UPnP protocols).
Note. As an alternative way to check media resource play back (in order to compare), the user can apply media player application (for example, VLC player) installed on PC, connected to the same local network as STB.

3. If the audio issue related to certain IPTV channel (or media file):

    1. Set different audio track (if available).
    2. Make sure that the parameters for audio play back of channel (or media file) comply with the STB specification.

Note. TV channel (or media file) audio playback parameters can be obtained, for example, using VLC player application – Tools / Media Information.

4. if the issue does not depend on the type of media resource (audio playback does not resume), make sure that the correct sound settings are applied on the STB:

  • For comparison, check the sound on other outputs (HDMI, CVBS, S/PDIF).
  • If there is no sound over HDMI, check the following STB settings: Selecting video interface mode HDMI / DVI
  • Check Audio settings (initial volume, audio mode, audio output on SPDIF / HDMI, etc.)On the side of the audio device:
    • Make sure that the audio device (TV, audio system, speakers, headphones, etc.) is in proper working order;
    • Make sure that the audio device percieves commands from the remote control (for example, in the case of TV). Set the maximum audio level on the audio device (100%) - Do not change this setting until the issue is solved.
    • Check connection settings. Make sure that audio signal transfers to the expected audio output (HDMI, CVBS, S/PDIF).

Note. In case TV or PC, with the headphones connected, no sound transfers to the inner speakers.

5. Check the cable connection of all devices involved in the audio path (1. From STB to audio device 2. From audio device to headphones or speakers if used).
6. If possible, try different audio cable and audio device.
