Kennex TV firmware for TP.SIS231.P83 main board and HV320WX2-201 panel

User question

Dove trovare firmware per TV kennex

Artificial Intelligence Response

Direct answer to the question

• Short answer: For Kennex TVs you’ll usually find firmware by searching for the main board code and LCD panel, not just the brand/model. The most productive sources are professional repair forums (e.g., Elektroda, Remont‑aud, Badcaps, Elektrotanya, PLCForum) and a few reputable commercial repositories (e.g., RomFlasher) that specifically list TP.SIS231.P83 images. Official Kennex support is worth trying, but is rarely published publicly.
• Key points:
  • Identify and search by main board (e.g., TP.SIS231.P83) and panel (e.g., HV320WX2‑201).
  • Prefer community‑vetted dumps and clearly panel‑matched builds.
  • Back up your original SPI (e.g., 25Q64) before any flash; the wrong file can brick the set.

Detailed problem analysis

• Why board/panel matter: In many budget/ODM TVs, firmware is tied to the main board’s SoC/chassis and the exact LCD panel timing (resolution, LVDS map, bit‑depth, polarity, scan direction). Kennex models are frequently based on universal SiS/TP platforms (e.g., TP.SIS231.P83). Two “Kennex NM32…” sets can require different binaries if their panels differ.
• What to search:
  • Main board: TP.SIS231.P83 (must match exactly; P82/P85 are different).
  • Panel: BOE HV320WX2‑201 (1366×768, typical 6‑bit LVDS; check suffix for timing variant).
  • SPI size: often 25Q64 (8 MB). Using a dump for the wrong size (e.g., 25Q32/25Q128) will fail or soft‑brick.
• Typical file types/names:
  • USB upgraders: allupgrade_*.bin or SIS231.bin (name can be loader‑dependent).
  • Full SPI dumps: raw 8 MB BIN images read from the 25Q64 chip.
• Symptoms of mismatch and meaning:
  • Inverted/rotated image or wrong colors: panel table mismatch (LVDS map A/B, swap, 6/8‑bit), not a power or T‑Con failure.
  • No backlight or no logo after USB flash: wrong binary or corrupt loader; restore by direct SPI programming.
• Recovery hierarchy: 1) USB emergency update via key combo. 2) Direct SPI reflash with programmer and the correct, panel‑matched dump. 3) Main board swap with same code pre‑configured for a matching panel.

Current information and trends

• Most Kennex firmware is exchanged in repair communities rather than official portals. For TP.SIS231.P83 in particular, technicians routinely share verified dumps per panel/resolution and discuss USB recovery methods. Commercial repositories also list Kennex‑branded images for TP.SIS231.P83 (often tagged by SPI size and panel).
• Trend: Newer platforms (e.g., TP.MS3463/MS3663, RTD/Vestel) increasingly use signed update packages; older SiS231 generations remain serviceable with raw BINs, making backup and restore practical.

Supporting explanations and details

• USB emergency update (common flow for TP.SIS231.P83; exact keys can vary by OEM):
  • Prepare a small USB drive (≤8 GB), FAT32.
  • Place the update file in root, named as required by your loader (try SIS231.bin or allupgrade_*.bin as documented with the file).
  • With TV unplugged, insert USB. Hold the TV’s physical Power (or sometimes Vol‑) button, plug AC, keep holding until LED blinks fast or the USB LED flashes, then release.
  • Wait 3–8 minutes; the TV should auto‑reboot. Remove USB once it boots to the wizard.
• Direct SPI method (when the USB path doesn’t start or unit is bricked):
  • Identify the flash (commonly 25Q64 SOIC‑8). Record orientation (pin‑1 dot).
  • Use a 3.3 V programmer (CH341A with 3.3 V adapter), SOIC‑8 clip or hot‑air to lift.
  • Always read and save at least two matching backups of your original contents; verify checksums.
  • Erase, program, and verify the new BIN; reassemble and test.
• Service/Factory menu alignment:
  • If image is present but mirrored/upside‑down or with color errors, enter service menu (typical sequences: Menu→1147, or Source→2580, varies) and adjust Panel Type, LVDS Map, Bit‑depth, Scan Reverse. Note: some Kennex builds lock these items; then you must use a correctly matched firmware.

Ethical and legal aspects

• Firmware and dumps are often copyrighted by the OEM/chassis vendor. Use only for legitimate repair of your own device.
• Commercial sellers may repackage community dumps; evaluate reputation and refund policy. Avoid files of dubious origin or bundles with malware.
• SPI images can include device identifiers (MAC address, EDID, serial). Sharing your own dump publicly may reveal unique IDs—scrub if you must share.

Practical guidelines

• Where to look first:
  • Professional repair forums: Elektroda, Remont‑aud, Badcaps, Elektrotanya, PLCForum. Search by “TP.SIS231.P83 1366x768” or “HV320WX2‑201 dump”.
  • Commercial repositories: reputable sites that list Kennex or TP.SIS231.P83 by SPI size/panel.
  • Official channels: try Kennex regional support or authorized service partners for your exact model.
• What to post when requesting help:
  • Full TV model and chassis label photo.
  • Main board code (TP.SIS231.P83 silkscreen) and clear board photo.
  • Panel label photo (HV320WX2‑201 including suffix).
  • Flash chip marking (e.g., Winbond 25Q64FVSIG).
• Best practices:
  • Use a UPS or stable bench PSU during USB updates.
  • Prefer small, older USB sticks (2–8 GB) and FAT32.
  • Don’t cross‑flash P82/P83/P85 assuming “close enough”—they aren’t.
  • After success, disable “Hotel/Shop” modes and perform factory reset to clear mismatched NVM.
• Common pitfalls and fixes:
  • No USB update trigger: try different stick, rename file, other USB port, hold Vol‑ instead of Power.
  • Boots but no RF/HDMI/audio: NVM table mismatch—perform factory reset, then re‑align options; if still bad, use a dump known for your exact panel.

Possible disclaimers or additional notes

• Not all Kennex models share the same loader; file names and key combos vary. Always read the notes that accompany the specific file you obtain.
• Some units ship with panels of the same model family but different timing tables; a “close” firmware may display an image yet still have color/scan defects—choose an exact panel match when possible.

Suggestions for further research

• Look for posts explicitly mentioning: “TP.SIS231.P83 + HV320WX2‑201 (1366×768) + 25Q64” and success confirmations.
• If your model is different (e.g., Kennex T.EME380.61 chassis), search and request within that chassis family—images are not interchangeable across chassis lines.
• If repeated attempts fail, consider sourcing a pre‑programmed TP.SIS231.P83 board pulled from a 32‑inch 1366×768 donor with the same panel.

Brief summary

• Best places to find Kennex TV firmware are technician forums and vetted repositories; search by main board and panel, not just brand/model. For TP.SIS231.P83 sets (e.g., NM32 variants with HV320WX2‑201), obtain a panel‑matched BIN, back up your original 25Q64, and update via USB or direct SPI. Verify functionality and panel mapping in the service menu; if incompatible, try a better‑matched build or reflash directly. If you share your exact model/board/panel details, I can narrow to a specific file and walk you through the safest update path.
