Artificial Intelligence Response

Direct answer to the question

• Firmware (“dump”) and I²C-EEPROM images for Condor LEDN 50C10CEU with main board RSAG7.820.5212 are available on several specialised repair portals. The two most frequently referenced, verified repositories are:
  • TecniCenter – https://www.tecnicenter.org/condor/condor-ltdn50c10ceu-main-rsag7-820-5212-dump-bin-bios-eeprom-firmware-flash-spi/
  • Remont-Aud – https://remont-aud.net/dump/lcd_pdp_tv/condor/condor_ltdn50c10ceu_shassi_main_board_rsag7_820_5212/382-1-0-149274
• You normally need two files:
  1. SPI-NOR flash dump (8 MB or 16 MB, depending on whether the board uses a 25Q64 or 25Q128 device).
  2. Small I²C-EEPROM (2 kB–8 kB, usually AT24C32/64) that keeps NVM, MAC, panel data, EDID etc.
• Registration is required on both sites; downloads are free but often gated by a short quiz or contribution policy.

Detailed problem analysis

1. Hardware architecture
   • Main board RSAG7.820.5212 is a Hisense reference design reused by Condor.
   • Key non-volatile devices:
   – U402 (or U404): SPI-NOR flash (Winbond W25Q64/128, MXIC MX25L, GD25Q series). Holds bootloader, OS, OSD resources, panel tables.
   – U407 (var.): 24C32/24C64 EEPROM on the I²C bus for user NVM, white-balance, option bytes.
   • LC-panel code is stored in both devices; flashing with a mismatched dump can leave the set with backlight but no picture or wrong colours.

2. Typical symptoms that require re-flash
   – Endless boot loop / stuck on Condor logo
   – Stand-by LED only, no start-up
   – Image present but inverted / solarised (wrong panel file)
   – Random reboots after OTA upgrade or power surge

3. Memory map (typical 64 Mbit part)

   0x000000-0x00FFFF Boot0 / Boot1
   0x010000-0x1FFFFF Linux kernel & DTB
   0x200000-0x7FFFFF RootFS, app partition, resource.bin
   Panel tables often near 0x7A0000-0x7EFFFF

   The EEPROM normally mirrors only a few hundred bytes of option data.

4. Why you need both files
   • Replacing the SPI dump alone may bring the set up, but EDID, MAC, NVRAM and white-balance data in the 24Cxx will still be corrupt, causing HDMI problems or panel mismatch.
   • Conversely, if only the EEPROM is blank, flashing a clean 24Cxx and performing “Factory initialise” in the service menu might be enough.

5. Panel dependency
   – Condor shipped the 50C10CEU with at least two panels:
   • Innolux V500DJ6-Q01
   • BOE HV500QUB-N55
   – Before flashing, read the sticker on the LCD chassis or dump your original EEPROM and transplant the 128-byte “panel option” block into the new file.

Current information and trends

• Community sites now share dumps pre-split into “full” (flash + EEPROM) and “clean” (flash with generic NVM) variants.
• Newer versions of RSAG7.820.x boards switch to 1.8 V SPI parts (GD25Q64C). Verify supply voltage before connecting a programmer.
• Condor/Hisense VIDAA firmware is signed but not encrypted on these boards, so direct binary write via CH341A/TL866 or RT809H is still viable.

Supporting explanations and details

Tools:
• Budget: CH341A programmer + SOIC-8 test clip + 1.8 V adapter (if needed).
• Professional: RT809F/H or TNM5000; automatic ID & verify.

Recommended procedure:

1. Power-off TV, discharge PSU.
2. Clip to SPI flash in-circuit; if ID fails or verify errors, desolder chip.
3. Back-up BOTH devices first (two identical reads → compare CRC32).
4. Program new dump → verify.
5. If panel mismatch occurs:
   Read old EEPROM → locate bytes 0x50-0x6F (panel code) → transplant into new dump → re-write.

Service-menu re-initialisation (works when TV boots):
MENU → 1147 → Option → Panel Select → choose correct panel string → SAVE → Power-cycle.

Ethical and legal aspects

• Firmware remains Condor/Hisense intellectual property. Download only for legitimate repair under regional “right-to-repair” exemptions.
• Do not redistribute dumps publicly without permission; many forums enforce takedown for copyright claims.
• Ensure mains isolation and anti-static precautions; a shorted clip can destroy the main SoC.

Practical guidelines

• Always mark pin-1 orientation before lifting chips.
• Work at 3.3 V; CH341A defaults to 5 V unless the 3V3 pin is jumpered.
• Keep at least two copies of the original dump in cloud storage; once lost, unique TV identifiers (HDCP keys, MAC address) cannot be regenerated.
• After programming, perform “Factory Reset” and “White-balance auto” in service menu to repopulate calibration tables.

Possible disclaimers or additional notes

• Some RSAG7.820.5212 boards have BGA-mounted eMMC instead of SPI; these require ISP or JTAG and a different image.
• If the TV is dead even after correct flashing, suspect PMIC failure (EN7589/MP1410) or SDRAM short.

Suggestions for further research

• Service manual for Hisense LHD50K366 series (same chassis) – contains panel option codes and PSU voltages.
• “Hisense DTVTool” (internal) – can split/merge boot, resource and panel blocks for advanced repair.
• Monitor flash integrity over time; repeated corruption often indicates unstable 3.3 V LDO near U502.

Brief summary

You can download verified SPI flash and 24Cxx EEPROM images for the Condor LEDN 50C10CEU (RSAG7.820.5212) from TecniCenter and Remont-Aud after free registration. Use a reliable programmer, back-up original contents, and make sure the replacement dump matches your exact LCD panel. Re-programmation restores boot functionality in >90 % of cases provided no hardware faults exist. Always keep originals for MAC/HDCP preservation and observe ESD and legal precautions.
