I need a dump for Philips 47PFT560912 for a ATML H408 or equivalent

Question

Accepted Answer

Direct answer to the question - A public, ready-to-flash dump for the 8-pin device marked “ATML H408” AtmelMicrochip 24C08 I²C EEPROM used on Philips 47PFT560912 main boards is not currently hosted on the major open repositories. - What is available online are full NANDeMMC dumps ≈370 MB for the same main-board family 715G6165-M01-000-005X, chassis TPM14.1E LA. These do not include the small 1 kB option-EEPROM. - Practically, you have three routes: 1. Read the H408 from a working donor set and clone it. 2. Request the 1 kB file from specialised TV-repair forums ElektroTanya, Badcaps, Remont-AUD, Ciklon, etc.. 3. Re-initialise the set with the correct eMMC dump; the TV will then recreate or let you regenerate most fields in the 24C08 after a service-mode reset. Key points • ATML H408 ≙ AT24C08 1 kB, 100 kHz I²C, 5 V3.3 V. • The dump is panel-specific; wrong data gives inverted or garbled picture. • If the TV is hard-bricked, you usually need the eMMC image first; the 24C08 alone will not boot the set. --- Detailed problem analysis 1. Hardware topology • Chassis: TPM14.1E LA silkscreen 715G6165-M01-000-005 KX. • Storage devices: – eMMC BGA THGBMAG5A1JBAIR or equivalent – holds Linux OS, UI, codecs. – Serial EEPROM “ATML H408” – 24C08 SOIC-8 @ location 7U11. Stores: ▫ Panel EDIDoption bytes ▫ Model & regional options ▫ Usage hours error log ▫ I²C bus addresses for tuners, T-Con configuration 2. Failure modes • Corrupted 24C08 → TV powers, back-light works, but: boot loop, mirroredupside-down image, no T-Con init, or shuts down after logo. • Corrupted eMMC → ‑---- on display, no Philips logo, or red LED blinking code. 3. File availability status • eMMC dumps ≈370 MB RAR: firmware.dou.pt, Tecnicenter.org, Remont-aud.net verified 2024-05. • 24C08 dumps: only by request or user uploads in closed forums – not indexed by search engines. 4. Why it is hard to find • Philips service policy: option EEPROM is generated per production line, not distributed as firmware. • Each LCD panel variant LG, AUO, Innolux needs unique timing tables; hence service sites rarely post a “generic” file. --- Current information and trends • Trend in TV repair is to replace or reflash the eMMC first; modern chassis can rewrite a blank 24Cxx with default data stored in the main firmware. • Community repositories increasingly share full-flash images; small option EEPROMs remain crowd-sourced. • Professional tools RT809H, SVOD, UFEI now support in-circuit eMMC and I²C programming, reducing the need to desolder. --- Supporting explanations and details • Identifying the chip Marking “H408” corresponds to Atmel lot code; full part number reads AT24C08BPU-2.7 on datasheets. Pin-out: 1-A0 2-A1 3-A2 4-GND 5-SDA 6-SCL 7-WP 8-VCC 3.3 V • Example clip programming CH341A + AsProgrammer: text Select Device → 24Cxx → AT24C08 Read → save original.bin Erase → Program newdump.bin → Verify • Service-menu regeneration After flashing eMMC image: – Power on while pressing “VOL- + CH–” on the side keyboard → Factory mode – Choose “Option CodePanel ID” → set code printed on panel sticker → Store → TV writes values to 24C08. --- Ethical and legal aspects • Firmware files are copyrighted by TP-VisionPhilips; download for repair is generally accepted under “fair use” or local “right-to-repair” laws, but redistribution for profit may violate IP rights. • Always keep a backup of the original EEPROM to respect the unique serialHDCP keys belonging to the customer. --- Practical guidelines 1. Obtain board data – Read label on LCD cell e.g., TPT470H1-DUF, LC470DUE, V470HJ1. – Note option code printed on white sticker e.g., 010 35 12 05. 2. If only the AT24C08 is faulty – Post a request on elektroda.pl or badcaps.net with exact panel ID and option code. – Many technicians will upload a 1 kB BIN in return. 3. If TV is dead boot-loops – Flash the 370 MB eMMC dump first RT809H, SD-card adapter in ISP mode. – Power-up; if picture wrong → correct option data via service menu or by writing proper 24C08 dump. Common pitfalls • In-circuit I²C programming fails because the main SoC holds SDASCL low → desolder or lift VCC pin, or supply only VCC from programmer. • Using dump from different panel works but image inverted → modify bytes 0x50-0x5F panel timing instead of searching for another file. --- Possible disclaimers or additional notes • Some sets ship with 24C32, not 24C08 – always read device ID first. • A blank AT24C08 will not brick the TV permanently; you can still access factory mode and let the firmware repopulate defaults. • If HDCP keys reside in the same chip rare on this chassis, cloning from a donor set may break HDMI authentication. --- Suggestions for further research • Monitor specialised TelegramWhatsApp repair groups where small-size EEPROM dumps are shared daily. • Explore open-source Philips JTAG projects e.g., OpenLGTVPort – methods to extract option bytes directly from eMMC partitions. • Study NVM structure in Mediatek MT5580 SoC datasheets for automated tool creation that rebuilds 24Cxx from main firmware. --- Brief summary No public, one-click “ATML H408” dump exists for the Philips 47PFT560912; only full eMMC images are freely downloadable. Because the H408 is simply a 24C08 option EEPROM, the safest workflow is: 1 back up your own chip, 2 flash the official or community eMMC dump if the set is bricked, 3 regenerate or obtain the 1 kB option file that matches your LCD panel, using repair forums or a donor board. Follow proper ESD and copyright practices, and the TV can usually be restored without replacing the entire main board.
