Philips 47PFT5609/12 ATMLH408 EEPROM Bin File Request – TV Not Booting

User question

I'm looking for a bin file (EEPROM dump) for the ATMLH408 chip used in the Philips 47PFT5609/12 TV. The unit is not booting properly, and I'm hoping to reflash the EEPROM to fix it.

Artificial Intelligence Response

Direct answer to the question

• A publicly-available, manufacturer-approved bin file for the ATMLH408 (serial EEPROM) used on the Philips 47PFT5609/12 main board is not officially distributed on the open Internet.
• Philips/TP-Vision supply such device-specific dumps only to authorised service partners.
• For field repair you have three practical options:

1. Extract and back up a dump from a working donor board or identical TV.
2. Request the file or a pre-programmed IC through an authorised Philips service centre or professional firmware repository.
3. Start with a “clean” (all 0xFF) or service-menu-initialised EEPROM and let the SoC repopulate default data, then finish alignment from the service menu.

Key points:
– ATMLH408 is just Atmel’s date/lot code; the device is usually an AT24C32 or AT24C64 I²C EEPROM (4 kB or 8 kB).
– Always read and save the present contents before erasing or rewriting.
– Wrong or region-mismatched data may leave the TV with no back-light, colour errors or constant reboot.

Detailed problem analysis

1. Device role
   • The serial EEPROM stores panel ID, EDID, audio/video alignment, option codes and usage data.
   • System firmware (Linux + GUI) resides in a separate eMMC (e.g. THGBMAG5A1JBAIR, 4 GB). Corruption there – not in the EEPROM – is the commonest “no-boot” root cause.

2. Identifying the chip
   • On chassis 715G6165-M01-000-005K the device reference is often U804 (silkscreen varies).
   • Full part number (readable under magnification) determines programmer settings:
   – AT24C32 → 4096 bytes (0x1000)
   – AT24C64 → 8192 bytes (0x2000)

3. Typical failure modes
   a) Single-byte corruption during brown-out → boot loops or dark panel.
   b) eMMC bad blocks → stuck logo, random reboots, or no video while LED blinks.

4. Repair decision tree

If the dump differs wildly from nominal data size or is unreadable, assume EEPROM damage.

Current information and trends

• Independent repair sites (firmware.dou.pt, elektroda.pl) now publish full eMMC dumps (≈ 370 MB) for this model; these cure ~80 % of “dead” boards when written to a new eMMC.
• Sharing of copyrighted EEPROM images remains restricted; reputable forums only exchange them privately between verified technicians.
• “Blank-EEPROM-auto-initialisation” is confirmed to work on many TP-Vision chassis from 2013-2016, provided you enter service mode afterward to choose the correct LCD panel code.

Supporting explanations and details

Programming workflow (AT24Cxx example):

1. Disconnect AC, discharge PSU.
2. Clip SOIC-8 test hook or desolder chip.
3. Select device in programmer GUI, read three times → compare → save orig.bin.
4. If using donor file: erase, program, verify.
5. If using blank method: create file of correct length filled with 0xFF, write, verify.
6. Re-install, power-up. TV should either boot normally or enter “Factory Initialisation” screen.

Service-menu access after blank initialisation:
Stand-by → 062596 + MENU/INFO. Set:
• Option Code (model/variant), e.g. 47PFT5609/12
• Panel Type (check sticker on panel, e.g. V470HJ1-PE1)
• 3D, Ambilight flags if present

Ethical and legal aspects

• Philips firmware, EEPROM data and option codes are proprietary; unauthorised redistribution may infringe copyright.
• Use only data acquired from your own device, an owner-consented donor board or an official service channel.
• Ensure compliance with local ESD, electrical-safety and consumer-protection regulations when servicing mains-powered equipment.

Practical guidelines

Recommended tools:
– CH341A + 1.8 V/3.3 V adapter or TL866II Plus programmer
– Pomona 5250 or SOIC-8 200 mil test clip
– Hot-air station if chip removal necessary
– Multimeter/oscilloscope to verify SDA/SCL integrity (<100 kHz pull-ups to 3.3 V)

Common pitfalls and remedies:
• In-circuit programming fails → remove chip (pull-ups or MCU hold SDA low).
• TV dead after write → verify file length, byte offset, endianness; restore original dump.
• White screen / wrong colours → enter service menu, correct panel ID.

Possible disclaimers or additional notes

• A completely blank EEPROM may not work on very early software revisions that expect checksum bytes: keep the original dump as a safety net.
• If the eMMC is failing (SMART ECC errors) the TV may overwrite a freshly programmed EEPROM with corrupt option bytes on first boot.

Suggestions for further research

• Investigate JTAG/UART diagnostics on MediaTek MT5560 SoC used in this chassis for deeper boot-log insight.
• Compare CRCs in multiple known-good EEPROM dumps to map critical regions vs. adjustable settings.
• Explore open-source tools (e.g. Bus Pirate, sigrok) for non-destructive I²C sniffing during power-on.

Brief summary

An exact ATMLH408/AT24Cxx bin for Philips 47PFT5609/12 is not legally posted in the public domain. Your safest paths are:
1) pull a dump from a working donor board,
2) obtain it via authorised Philips channels, or
3) initialise the set with a fully blank EEPROM and then configure options through the service menu.

Always back up the original contents, verify hardware health, and consider that eMMC corruption—not EEPROM—is the more frequent cause of boot failure in this chassis.
