autorun.upg) is released. Key points
• Chassis: TPM14.2E LA • Main board P/Ns typically 715G9717-M0x-xxx
• Flash devices: 8 Mbit SPI-NOR for boot + 4–8 GByte eMMC for OS
• Access methods: service USB update → UART recovery → ISP/JTAG → chip-off
• Legal / warranty risks: dumping voids warranty and may infringe copyright.
Hardware topology
• SoC: MediaTek MT5595 (Quad-A17/Quad-A7, 4 K TV platform 2014–2015).
• Boot chain: SPI-NOR (U-Boot & first stage) → eMMC (kernel, Android, userdata).
• Security: no secure-boot fuse in this generation, so direct re-flash is possible, but wrong panel parameters will brick the set (LVDS/T-Con data stored inside NVM partition).
Normal recovery path (no programmer required)
a) Download latest firmware “50PUK6809_12_fus_xxxx.zip” from Philips or Toengel archive.
b) Format USB stick FAT32, copy autorun.upg to root.
c) Unplug TV, insert USB, press-and-hold OK on remote (or rear joy-stick), re-apply mains.
d) LED starts blinking; progress bar appears. Takes 5-15 min.
e) If successful the TV reboots twice and factory-resets itself.
When USB recovery fails
Symptom: no logo / stuck in short boot loop / UART shows “Boot fail”. Causes:
• Corrupted SPL in SPI-NOR.
• Bad blocks in eMMC (common after 4–5 years).
• Power loss during previous update.
Low-level repair workflow
1) Identify exact board number (e.g. 715G9717-M01-B00-005K) and panel code (printed on flat-cable label).
2) Search forum dumps: keyword “TPM14.2E LA dump 715G9717 eMMC”. Ensure panel code matches.
3) Back-up original chips before writing, even if corrupted (evidence & MAC/Netflix keys).
4) Programming options
• ISP to eMMC test pads: DAT0,CMD,CLK,VCC, VCCQ, GND – use RT809H, Easy-JTAG Plus or SD-Wire rig.
• Chip-off re-ball and program in BGA153/169 socket – higher success, but board risk.
• SPI-NOR (8-pin W25Q64) can be read with CH341A + 1.8 V adapter.
5) Program good dump, verify CRC, reassemble, run service-menu “Clear NVM”, then regular firmware upgrade to align serial & country codes.
Memory map (TPM14.2E LA)
• 0x000000-0x00FFFF SPL (512 KiB, SPI)
• 0x010000-0x07FFFF U-Boot (SPI)
• eMMC partitions
Typical pitfalls
• Dump from 55-inch sibling will turn picture negative or show “no back-light” – caused by wrong TCON gamma table.
• eMMC “program OK” but still boot-loops – the chip itself is worn-out; replace with new Samsung/Kioxia 8 GB and pre-program dump.
• Netflix/HDCP keys stored in secure world of SoC; replacing eMMC keeps keys intact, replacing SPI-NOR does not affect them.
• Since 2018 (TPM17, TPM18) Philips introduced signed BL, making raw dumps useless; TPM14.2E LA is still unsigned, so re-flash remains viable for repair shops.
• Growing use of ISP pogo fixtures allows in-circuit eMMC programming without hot-air.
• Community projects (e.g., libeMMCISP) automate DAT0-only flashing, reducing risk of pad damage.
• Supply chain shortages make main boards costly; board-level flash repair is economically attractive in 2024.
Analogy: Think of the SPI-NOR as the BIOS chip in a PC and the eMMC as the SSD containing Windows. If the BIOS is intact, the TV can boot recovery from USB; if the BIOS itself is erased, you need a programmer just like re-flashing a corrupted PC BIOS.
Example UART log (working set):
U-Boot 2014.07 (TPM14.2E)
DRAM: 2048 MB
NAND: eMMC: Samsung 8G
Booting kernel from mmc 0:1 …Corrupted set shows:
U-Boot SPL 2014.07
### ERROR: CRC mismatch, halting• Firmware binaries are Philips intellectual property; sharing them publicly may breach copyright.
• Performing chip-level operations voids any remaining warranty and may violate local consumer law if done on rented/financed devices.
• Ensure data privacy: recorded channel lists, Wi-Fi passwords reside in userdata partition—wipe before handing dumps to third parties.
Implementation checklist
☑ Confirm power rails (3V3, 1V2, 1V8, DDR3 1V5) are present before blaming firmware.
☑ Use antistatic mat and 100 °C pre-heat before BGA lift.
☑ After re-flash, enter service menu > Option Code to restore model ID (found on rear label: 064 75 68××).
Challenges & mitigation
• No schematic? → Service manual TPM14.2E LA free at Elektrotanya (link below).
• Donor dump language mismatch? → Language pack updated automatically after first internet sync.
• All procedures are at your own risk; wrong voltage on programmer can irreversibly destroy flash.
• Some online “universal” dumps are truncated (4 GB instead of 8 GB). Always compare size with original chip.
• If you do not own rework equipment, purchasing a complete tested main board is often cheaper (< 80 € used).
• Study Philips service training document “Advanced Level 3 – TPM14 platform”.
• Explore open-source eMMC ISP tools (e.g., edl.py, easyeMMC) that support DAT0 mode.
• Monitor forums (Elektroda forum408, RepairAllTV Slack) for updated, panel-matched dumps.
• Investigate replacing eMMC with newer industrial grade parts to prolong TV lifespan.
Resources
The 50PUK6809 uses the TPM14.2E LA chassis with separate SPI-NOR and eMMC flash devices. Try the official USB autorun.upg recovery first; if bootloader damage prevents this, a hardware flash dump/restore is required. Obtain a panel-matched binary from professional forums, program it via ISP or chip-off with a suitable programmer, and observe legal and safety precautions. For non-specialists, sourcing a replacement main board remains the safest repair path.
