• VOX UHD 55ADS316BU is a 55-inch, Direct-LED, Android-based 4 K Smart-TV (3840 × 2160, Android 9.0) equipped with DVB-T2/C/S2 tuners, 3 × HDMI, 2 × USB, LAN/Wi-Fi/Bluetooth, Dolby-Audio 2 × 8 W, HDR10/HLG and Hotel-Mode functions.
• Firmware is updated either OTA (recommended) or manually via USB, but the exact package depends on the mainboard fitted to your set (most frequently CV9632H-A50 for the ADS316/ADW series).
• For service-level recovery (logo-loop, no-boot, black-screen) you must identify the mainboard P/N printed on the PCB and flash the matching “MstarUpgrade.bin / allupgrade…bin” image with the hardware-key procedure described below.
Hardware platform
• Panel: 55 in, 8-bit + FRC, 60 Hz.
• SoC: Mediatek / MStar MSD93xx family (quad-core Cortex-A53, Mali-T820 GPU).
• Memory options encountered in the field: 1.5 GB LPDDR3 + 8 GB eMMC or 2 GB + 16 GB eMMC, depending on production lot.
• Mainboards reported: CV9632H-A50 (common), TP.MS638.PB83 (early batches), HK.T.RT2841P838 (rare).
• Power section: separate PSU (12 V or 19 V rail) feeding buck converters on mainboard (1.0 V, 1.2 V, 1.8 V, 3.3 V).
Typical failure modes
a) “Stuck on VOX / Android logo, then reboots” – 70 % of service cases.
Root causes: corrupted /acha partitions, worn-out eMMC blocks, interrupted update.
b) “Backlight on, no picture” – missing LVDS voltage or panel key mismatch (incorrect firmware).
c) “Dead set, red LED only” – 12 V present, but 3.3 V regulator short (check AOZ2261/AIS212).
Standard recovery hierarchy
• Level 1 – User OTA update: Settings → About → System update. Requires working Android shell.
• Level 2 – Factory reset: Power → Volume- (hold) while plugging AC → Recovery menu → Wipe data.
• Level 3 – Forced USB boot: correctly named *.bin on FAT-32 stick, hold TV-key (or CH+ on side keypad) → LED blinks → progress bar appears.
• Level 4 – UART bootloader / eMMC ISP programming (for technicians).
USB upgrade key points
• Format flash drive ≤8 GB, FAT 32, MBR.
• Copy single firmware file to root. Many VOX-branded packages are named:
– MstarUpgrade.bin (MStar MSD93xx),
– allupgrade_msd638_4G_1G.bin (TP.MS638),
– p631_upgrade_package.img (RTD).
• Hold the physical power button, plug AC; release once LED flashes quickly / screen turns blue.
• Wait 5-15 min; TV reboots to Android first-boot wizard.
• VOX’s 2023 production migrated to Android 11 (AOSP-based) on later ADS3xx models, but 55ADS316BU remains officially on Android 9 with security patches to 2021-10.
• Mainboard suppliers are phasing out 8 GB eMMC variants; replacement boards ship with 16 GB and require matching “_16G” firmware. Mixing images causes panel mismatch or mute-audio faults.
• EU Ecodesign 2023/1 limits SDR power to 66 W for 55-inch 4 K TVs; firmware after v1.12.06 adds automatic ECO dimming to comply.
• Why exact board P/N matters
Panel EDID tables, PWM backlight parameters and DDR drive strengths are stored in the file; a wrong image often boots but shows pink/green snow or shuts down backlight.
• Console monitoring (optional)
Attach USB-TTL (3.3 V) to CN-DEBUG (TX/RX/GND). Baud 115200. Typical healthy log ends with:
“Bootanimation: exit, starting Launcher3”. Continuous “mmc blk error -110” means eMMC wear.
• Firmware is copyrighted by the ODM (MTC/TPVision). Distributing full images publicly may violate license terms; obtain from official VOX portal or authorised service partners.
• Flashing service SW invalidates consumer warranty unless performed by authorised personnel.
• Always disconnect mains and respect high-voltage zones (>400 Vdc on PSU PFC stage).
• No public Android 11 build exists for 55ADS316BU as of June 2024; any file claiming so is unofficial.
• If your set uses TP.MS638.PB83 the procedure differs (boot-key is VOL- on remote).
• Panel part number (e.g., V550DJ6-QDPE) is encoded inside firmware; mismatching panel= no-backlight.
• Monitor VOX EU support portal for future Android 10/11 upgrade packs.
• Explore open-source AOSP TV builds (though DRM keys and Tuner HAL are proprietary).
• Investigate eMMC health via cat /proc/healthinfo from adb shell once device boots.
The VOX UHD 55ADS316BU is a 55-inch Android 9 4 K TV built around MStar CV9632H-A50 (or equivalent) hardware. For feature updates or to recover from boot-loop/logo-freeze, first confirm the exact mainboard identifier, then perform an OTA or forced-USB firmware flash with the correct image. Use a small FAT-32 stick, follow the power-key sequence, and never interrupt the process. If flashing does not start or completes but the fault persists, suspect eMMC wear or PSU instability and proceed with board-level repair or replacement.
