Horizon 50HL7590U/B firmware

Artificial Intelligence Response

Direct answer to the question

  • The Horizon 50HL7590U/B uses a Vestel mainboard family, and its firmware is hardware‑specific (board revision, panel code, tuner, region). It is not safely replaceable with a “generic” image.
  • First try OTA update from the TV menu. If the set is unresponsive or OTA fails, the correct USB service package must be obtained from Horizon/authorized service based on your unit’s serial number, mainboard code, and panel code.
  • Do not flash firmware obtained for a different mainboard/panel; mismatches commonly cause black screen, mirrored/doubled image, boot loops, or permanent brick.

Key points

  • Identify: mainboard code (e.g., 17MB170/17MB180/17MB211x), LCD panel code (e.g., VES500QND…).
  • Preferred update path: OTA via Settings. Service USB update only with the exact, signed package for your hardware.
  • Typical recovery trigger: FAT32 USB ≤32 GB with the provided files at root; plug AC while holding OK on the original remote until LED flashes rapidly (procedure varies slightly by board).

Detailed problem analysis

  • Platform: Horizon 50HL7590U/B is a 50‑inch 4K Android/Smart TV built on a Vestel chassis. Vestel’s software stack binds panel timing tables (TCON parameters), tuner options, regional apps, and DRM provisioning to the mainboard BOM. As a result, “close enough” firmware rarely works; the panel LUTs and EDID/option bytes must match your exact panel (commonly VES50xx… for 50").
  • Update channels:
    • OTA (Over‑the‑Air): Signed packages are offered by model/region and validated by the bootloader. This is safest and preserves app/DRM provisioning.
    • Service USB: Used when OTA is impossible (boot loop, system corruption). Images are board‑ and panel‑specific and often named after the mainboard (e.g., upgrade_mb170.bin or MB1xx_en.bin with companion resource files). The bootloader checks signatures and option compatibility.
  • Failure modes that look like “needs firmware”:
    • Boot loop at Horizon/Android logo: often corrupted eMMC partition or bad blocks; reflashing may help, but failing eMMC will relapse.
    • No picture with backlight on: common symptom of panel mismatch (wrong panel profile in firmware) or TCON/panel power issue.
    • Mirrored/double/solarized image: panel table mismatch; sometimes correctable in service menu if the right panel profile exists, otherwise requires the right firmware package.
    • Dead/no USB recovery reaction: can be USB incompatibility, wrong file naming, corrupted bootloader/SPI, or hardware fault (eMMC/PMIC).
  • Hardware dependencies:
    • Mainboard families you’re likely to see in this model generation: 17MB170, 17MB180, 17MB211/211S. Each requires its own image and often sub‑revisions.
    • Panel codes typically start with VES500… for 50", and exact suffix matters (timing tables differ by suffix).
    • DRM keys (e.g., Widevine L1) and streaming entitlements reside in secure storage and are not present in “dump” images; losing them breaks premium streaming even if the TV boots.

Current information and trends

  • Vestel-based sets continue to enforce secure boot and board‑/panel‑specific packages. Public distribution of full service images remains limited; OEMs prefer OTA for end users and reserve USB packages for authorized service.
  • Android TV builds on 2019–2021 Vestel boards typically receive limited major‑version upgrades; by 2024–2025 many units are on security/maintenance updates only. Expect app/DRM requirements (Widevine L1, HDCP 2.2/2.3) to remain strict; preserving device keys is essential.
  • Field practice in 2025: technicians frequently fix boot loops by eMMC replacement/reprogramming on 17MB1xx/2xx boards; simple reflash is insufficient when eMMC is worn.

Supporting explanations and details

  • Why matching matters: Panel timing, gamma, VCOM, and 10/12‑bit LUTs are compiled into the package; mismatched tables yield distorted or no image. Tuner/DVB option bytes also control region features and CI+ behavior.
  • USB media quirks: Older Vestel bootloaders are picky—use a small USB 2.0 stick (2–16 GB), MBR‑partitioned, FAT32, no other files. Avoid exFAT/NTFS and USB 3.0 sticks.
  • Recovery triggers seen on Vestel:
    • Hold OK on the original IR remote while applying AC power until standby LED flashes rapidly.
    • Alternative on some boards: hold VOL− on TV side keys while plugging in.
    • Keep only one USB stick inserted in USB1 if ports are labeled.
  • Service menu access (if TV boots): common sequences are MENU 4725 or SOURCE 2580. Change only the panel option if you know the exact code; wrong settings can brick or damage the panel.

Ethical and legal aspects

  • Firmware packages are copyrighted and may include licensed components and device‑unique keys. Sharing or using unauthorized dumps may violate license terms and can strip DRM functionality.
  • Safety and warranty: Unauthorized service updates or opening the set can void warranty and create shock/ESD hazards. Follow ESD precautions and disconnect mains before disassembly.

Practical guidelines

Implementation steps (start with the least invasive):

  1. Identify your hardware
    • Photograph labels: rear cover (model/serial), mainboard silkscreen (e.g., 17MB170/180/211…), and panel sticker (e.g., VES500QND… complete suffix).
  2. Try OTA first (if the TV boots)
    • Android TV path typically: Settings → Device Preferences (or Support) → About/System Update → Check for updates. Keep the set on stable Internet and AC power.
  3. If OTA fails or TV is stuck/boot‑loops
    • Request the exact USB service package from Horizon/authorized service. Provide model, serial, mainboard, panel code, current symptoms.
    • Prepare a USB 2.0 stick ≤32 GB, FAT32, MBR. Place provided files at root exactly as named (do not rename).
    • Recovery: remove AC, insert USB in USB1, press/hold OK on remote, apply AC, keep holding until fast LED blink starts; then release and wait 5–10 minutes. Do not interrupt power. The TV should reboot into First Installation if successful.
  4. If there’s no LED activity/USB boot
    • Try a different small USB 2.0 stick/port; re‑format FAT32.
    • Recheck file names and that the image matches your board family.
    • If still dead: diagnose hardware—check standby/always‑on rails, 3.3 V/1.8 V/1.2 V regulators, and eMMC health. Many cases require eMMC reball/replace and programming with the correct image using a programmer.
  5. Post‑flash checks
    • Verify picture geometry/colors; if wrong, choose the correct panel option in Service Menu or reflash with the panel‑matched package.
    • Confirm DRM (Widevine) and streaming apps work; if not, keys may be lost—requires authorized service.

Potential challenges and mitigation

  • USB not recognized: use older/smaller USB 2.0 sticks, front USB1, and clean FAT32.
  • Mirrored/double image after flash: wrong panel table—do not try random profiles; get the right build for your panel.
  • Recurring boot loops: suspect worn eMMC; replacing only firmware won’t last.

Possible disclaimers or additional notes

  • Without the exact mainboard and panel codes, no one can safely provide you a working image; “same model” from another unit may still be incompatible.
  • Some regions/partners distribute only OTA to end users; service USB packages may be restricted to service networks.

Suggestions for further research

  • Obtain and record: full serial number, mainboard code, panel code, current firmware version (if accessible), and precise fault symptoms.
  • If you have UART pads exposed on the mainboard, capture boot logs; they quickly distinguish software corruption from eMMC or PMIC faults.
  • Explore service bulletins for your board family (17MB170/180/211) regarding eMMC endurance and recommended replacements.

Brief summary

  • Use OTA first; for service USB you must get an exact, signed package matched to your 50HL7590U/B’s mainboard and panel. Random or “close” firmware will often brick or misconfigure the panel.
  • Prepare proper USB media and follow the correct recovery key sequence. If recovery doesn’t start or the problem recurs, diagnose eMMC and power rails—many failures are hardware, not just firmware.

If you share the following, I can pinpoint the correct path: 1) mainboard code (17MBxxx), 2) full panel code (VES50… suffix), 3) serial number, 4) what the TV currently does (boots/loops/no image/mirrored), and 5) whether you can still access the settings or service menu.

User question

-SN 8522002 000129. 17mb170 VES500QNDT-2D-N41

Artificial Intelligence Response

Direct answer to the question

  • Your line describes a TV built on Vestel mainboard 17MB170 with panel VES500QNDT‑2D‑N41 (S/N 8522002 000129). For this hardware you must use the exact 17MB170 USB recovery/firmware package that includes the panel tables for VES500QNDT‑2D‑N41. There is no public, official download; obtain it via the brand’s authorized service or perform an OTA update if Android still boots.
  • Key points:
    • Do not flash “generic” 17MB170 or mismatched panel variants (e.g., VES500QNDH, different Nxx suffix).
    • Preferred path: OTA update (if the TV boots). If not, request the correct USB recovery from the brand/service.
    • If storage (eMMC) is degraded, a firmware write may fail; board repair or replacement preprogrammed for this panel may be faster.

Detailed problem analysis

  • Why the exact firmware matters:
    • The 17MB170 Android platform stores panel‑specific payloads: LVDS/V-by-One timings, color/gamma LUTs, TCON init, backlight driver parameters, and option bytes (region/tuner). The VES500QNDT‑2D‑N41 suffix identifies a specific timing/LUT set. Any mismatch typically produces mirrored/solarized image, wrong orientation, black screen with backlight on, or boot loops.
  • Architecture notes:
    • 17MB170 is a Vestel Android TV chassis used across multiple brands/models; the Android system image is similar but panel/PQ/option data are tightly bound to each production set.
    • The bootloader expects a signed recovery file (commonly upgrade_loader.pkg) and, for some packages, companion binaries (main image, panel/PQ, option bytes). Unsigned community “dumps” often omit DRM keys and may not pass signature checks.
  • Typical failure patterns and causes:
    • Boot logo loop or “dead Android”: corrupted system partitions or worn eMMC.
    • Sound without picture, or picture inverted/solarized: correct Android image but wrong panel profile loaded.
    • No response to USB update trigger: USB compatibility/formatting issue, wrong filename, or deeper bootloader/eMMC faults.

Current information and trends

  • In current service practice for Vestel Android lines, manufacturers do not host public service packages; recovery files are distributed to authorized service only. Field experience shows many 17MB170 issues are storage‑related (eMMC wear) after repeated power events/updates. Replacement mainboards preprogrammed for a specific panel/brand are commonly used when reflash does not hold or when time-to-repair is critical.

Supporting explanations and details

  • Service Menu (only if the TV boots):
    • Common entrances: MENU 4725, SOURCE 2580, or MUTE 1 1 1 9 (enter quickly).
    • Verify Panel Option matches VES500QNDT‑2D‑N41; do not change arbitrarily. Wrong setting can disable display until reflashed.
  • USB recovery preparation:
    • Use a small USB 2.0 stick (2–16 GB), MBR, FAT32. Avoid USB 3.0 sticks if detection is unreliable.
    • Place the provided files in the root; keep exact filenames (often upgrade_loader.pkg). Do not rename unless instructed by the package notes.
  • Forcing update (typical 17MB170 sequence):
    • Unplug AC power.
    • Insert the USB stick into USB1.
    • Press and hold OK on the original remote (alternatives seen: hold VOL− on TV side keys, or MENU+VOL+ on remote).
    • Plug AC power back in while holding; release when standby LED starts fast‑blinking.
    • Wait 10–15 minutes without interrupting power; TV reboots to first‑install if successful.
  • If image is wrong after a successful flash:
    • You likely installed a build without the exact N41 panel profile. Load the correct PQ/panel file via Service Menu → USB Operations, or reflash with the exact package that includes VES500QNDT‑2D‑N41 tables.
  • Hardware checks if flashing fails:
    • Power rails: verify 5VSB, main 12V, 3.3V, 1.8V rails are stable.
    • eMMC health: frequent update failures or immediate corruption after flash indicate worn eMMC; board‑level repair (eMMC replacement/reprogram) or mainboard swap is indicated.
    • LVDS/V-by-One cabling seated and undamaged; panel TCON flex intact.

Ethical and legal aspects

  • Full service firmware packages are copyrighted; redistribution is typically restricted to authorized channels. Community images may omit licensed components and DRM keys, limiting app functionality even if they boot.

Practical guidelines

  • If Android still boots:
    • Try OTA update only: Settings → About/Info → System update. Keep the TV on a stable power source and network during the update.
  • If the set does not boot or OTA fails:
    • Request the USB recovery for your exact set from the brand’s official support or an authorized service center. Provide: model, full S/N (8522002 000129), mainboard 17MB170, panel VES500QNDT‑2D‑N41.
    • If time‑critical or eMMC is suspect, consider a replacement 17MB170 board that is preprogrammed for your model/panel.
  • Common pitfalls to avoid:
    • Using firmware for other 17MBxx chassis (17MB130/180/211) or for similar‑looking panel codes (QNDH vs QNDT, different N‑suffix).
    • Renaming files arbitrarily or placing them in folders.
    • Interrupting power during update.

Possible disclaimers or additional notes

  • Button combinations and LED behaviors vary slightly by brand firmware revision. If the OK‑key method does not trigger, try the alternative key combos above.
  • Some recovery packages split Android image, panel PQ, and option bytes; all components must match your unit.

Suggestions for further research

  • Please confirm:
    • Brand and exact TV model from the rear label (for example, Horizon 50HL7590U/B or another brand using the same chassis).
    • Current symptom (boots to Android, stuck on logo, sound without picture, LED codes, etc.).
    • Whether you have the original remote and access to a small USB 2.0 stick.
  • With that, I can provide a model‑specific checklist (including expected software version, service menu map, and which panel/PQ filename to look for), and a decision tree to distinguish firmware vs eMMC vs panel/TCON faults.

Brief summary

  • Your set is a Vestel 17MB170 with panel VES500QNDT‑2D‑N41; it requires the exact matching recovery package. Try OTA if it boots; otherwise obtain the correct USB package from the brand/service, or use a preprogrammed replacement board if storage is failing. Avoid mismatched panel codes and generic images to prevent display errors or bricking.

If you share the exact model and symptoms, I’ll tailor the next steps and the precise recovery path for your unit.
