User question

Tôi cần tìm files .bin cho EEPROM Amply ONKYO TX-NA609

Artificial Intelligence Response

Direct answer to the question

• There is no openly published, direct download of a TX‑NA609 EEPROM “.bin” dump that I can verify today. Publicly available material and repair threads mainly cover the very close sibling TX‑NR609; dumps for that model do exist within repair communities but are typically shared privately on request. Use of a TX‑NR609 dump on a TX‑NA609 may work but is not guaranteed and carries risk. (phileweb.com)
• Practical ways to obtain a correct image:
  • Ask for a donor dump on specialist forums (Elektroda, Badcaps). Provide the exact memory IC part number and board revision. (elektroda.com)
  • Read the original device (if it still responds) with a programmer (preferable), even if the contents look corrupted—often parts can be salvaged.
  • As a last resort, evaluate cross‑flashing a TX‑NR609 dump after confirming hardware equivalence, then run a full official firmware update. Proceed only with a verified backup. (onkyo.com)

Detailed problem analysis

• Model relationship and implications:

  • TX‑NA609 is the Japan‑market variant of the 2011 Onkyo “609” platform; TX‑NR609 is the international variant. They share the same core architecture (HDMI/DSP board, main amp topology), but option bytes, region codes, tuner tables, and small NVRAM fields can differ. Cross‑flashing may yield region misconfiguration or feature anomalies (e.g., network services, OSD language, tuner bands). (phileweb.com)

• Which “EEPROM .bin” are we talking about?

  • The 609 platform uses multiple non‑volatile memories:
  • A large parallel NAND flash on the HDMI/DSP board (e.g., ST NAND256W3A2BN6E, 256 Mbit TSOP‑48) that stores DSP/NET firmware and the embedded Linux image. This is frequently the “BIN” people seek when the unit shows “Now Initializing,” “????????” for DSP versions, or is stuck after a bad update. (elektroda.com)
  • One or more small serial EEPROM/flash devices (I2C/SPI) on logic/front/HDMI boards that hold option bytes, model/region data, and calibration. These parts vary by sub‑board revision; you must identify the exact IC on your unit before requesting a dump.

• Typical failure modes on TX‑N(A)609 that lead people to re‑flash:

  • TI/Onkyo DSP BGA aging (D830K013… series) and/or corrupted NAND contents—symptoms include no delayed speaker relay click, no speaker icons, USB/NET “Now initializing,” and “????” in the service version screen. Many technicians reball/replace the DSP and then re‑program the NAND. (elektroda.com)
  • PCM9211 audio interface failure causing “USB/DLNA audio OK but tuner/analog/HDMI silent.” A few cases recover only after replacing PCM9211 and re‑updating firmware. Re‑programming alone won’t fix a dead PCM9211. (elektroda.com)

• Why you won’t find a vendor “EEPROM .bin” download:

  • Onkyo distributes firmware as update packages for NET/USB (not raw device dumps). Community members sometimes extract/decrypt these or share full NAND images, but distribution is informal and often account‑gated on repair forums. Official updates did exist for the 609 generation (including TX‑NA609 in Japan), but they are packaged installers, not BIN dumps. (itmedia.co.jp)

Current information and trends

• Current public threads show recent TX‑NR609 repairs where technicians re‑flashed the NAND (NAND256W3A2BN6E) and/or addressed HDMI‑board silicon (DSP, PCM9211). These confirm viable donor images for NR609 circulate, albeit privately. (elektroda.com)
• Japanese coverage confirms TX‑NA609 as the 2011 JP model and lists later firmware updates targeting network stability—evidence the platform is shared but region‑coded. (phileweb.com)
• Community practice remains: request dumps on Elektroda/Badcaps, or make your own dump from a working unit, then pair with a full USB firmware update to finalize. (elektroda.com)

Supporting explanations and details

• Identifying what to read/program:

  • NAND flash: Look for TSOP‑48 marked “NAND256W3A2…” near the DSP on the HDMI board (Q3002 in service materials). Size ≈ 32 MB. Requires a TSOP‑48 adapter and a programmer that handles ONFI NAND and ECC (e.g., RT809H, Wellon VP‑x with NAND option). (elektroda.com)
  • Small serial EEPROM/flash: 8‑pin SOIC (I2C 24Cxx or SPI 25Qxx), typically a few KB to a few MB. Use CH341A/TL866II/RT809H with 1.8 V adapter if required. Read in‑circuit only if you can guarantee bus isolation; otherwise desolder to avoid bus contention and corrupt reads.

• Verification workflow:

  • Always make at least two reads and compare CRC/MD5 to ensure a stable dump.
  • If writing a donor NAND, preserve device‑unique areas if present (some dumps include bad block/ECC maps). After programming, immediately perform a full official USB firmware update to normalize filesystems and module versions. (elektroda.com)
  • For small EEPROMs, back up the original content. If you try an NR609 image, keep your original so you can revert if the unit mis‑identifies the region or features.

Ethical and legal aspects

• Raw dumps likely contain copyrighted firmware and device identifiers (e.g., MAC, serial). Sharing/using donor BINs should be limited to repair/maintenance and exchanged privately. Many forums require login and discourage public posting of full images for this reason. (badcaps.net)
• If the unit was part of a service campaign (old HDMI board recall), using official service channels was previously encouraged; however, legacy programs ended years ago. Check with Onkyo support in your region for current options. (badcaps.net)

Practical guidelines

• If you want me to help find or prepare a matching BIN, please provide:
  • Exact IC needing the BIN (marking on the chip, e.g., “NAND256W3A2BN6E” or “24C64/25Q32…”) and on which board (HDMI/DSP, main, front).
  • Board code/revision silk‑screen (e.g., “UD*** Rev.”), and the receiver’s symptom set.
  • Whether you have a programmer and adapters (TSOP‑48, SOIC‑8, 1.8 V).
• Where and how to request a dump:
  • Post in Elektroda (Audio Service) and Badcaps (Audio Equipment). Include your chip ID, board rev, and that your model is TX‑NA609 (JP), asking if a TX‑NR609 dump is safe for your board revision. Be ready to reciprocate with your backup once repaired. (elektroda.com)
• Cross‑flash checklist (if you can’t locate NA609):
  • Confirm hardware identity: same HDMI board code and DSP generation as NR609.
  • Back up your original dump(s).
  • Program the donor NR609 NAND/EERPOM, power up on current‑limited bench supply, check for normal boot, then perform a complete USB firmware update for the 609 platform. Test all functions (HDMI, tuner, NET/USB, Zone 2). Abort if you see region/model mis‑match prompts; these can sometimes be corrected via hidden “Model Select” option only after a factory reset cycle. (reddit.com)

Possible disclaimers or additional notes

• There is no guarantee an NR609 BIN will be functionally identical on an NA609 due to region options; you can end up with wrong tuner bands or disabled services. Use only after confirming board equivalence and keep your original dump safe. (reddit.com)
• If your symptoms match PCM9211 or DSP BGA failure, programming alone won’t restore audio—hardware repair may be required. (elektroda.com)

Suggestions for further research

• Pull the TX‑NR609 service manual and parts supplements to find the exact reference designator of the memory you need (helps with forum requests). Multiple revisions exist; consult the latest “SM PARTS” PDFs. (elektrotanya.com)
• Search (and, if needed, post) in Japanese communities using “TX‑NA609 EEPROM ダンプ” or “TX‑NA609 NAND 書き込み.” The NA‑series is Japan‑only; JP users may have region‑correct dumps. The 2013 JP firmware notice is a good keyword anchor. (itmedia.co.jp)

Brief summary

• A public TX‑NA609 EEPROM/NAND BIN is not readily available; TX‑NR609 donor images exist within repair forums but must be used cautiously. Identify the exact memory IC first; for the HDMI/DSP board, the known NAND part is NAND256W3A2BN6E on this platform. Engage Elektroda/Badcaps for a donor image, back up your original, and, if you must cross‑flash, verify board equivalence and finish with an official USB update. If your unit’s failure is in the DSP or PCM9211, expect hardware work in addition to any re‑flash. (elektroda.com)

If you can share a photo of the target IC (top‑marking readable) and your board revision, I’ll help you determine the safest path (which dump to ask for, programming steps, and post‑flash checks).
