Installation Steps

  1. Extract the archive to C:\NeoProgrammer\ (avoid spaces in the path and do not run from a compressed folder).
  2. Install the CH341A drivers: Locate the Drivers folder inside the extracted package. Run CH341A_Install.exe as Administrator. Reboot if prompted.
  3. Run the main executable: Right-click NeoProgrammer.exe → Properties → Compatibility → Check "Run as Administrator" → Apply.
  4. Hardware setup: Connect your CH341A to the PC. Do NOT connect a chip yet. Open Device Manager. Under "USB Adapters," you should see "CH341A" or "USB-EEPROM." If you see an error, repeat driver installation.
  5. First launch: Open Neo Programmer. Click "Detect Device." If it says "CH341A found," you are ready. If it says "No device," try a different USB port (USB 2.0 is more reliable than USB 3.0).
  6. Configure settings: Go to "Settings" → "Programmer parameters." Set:

    3. TV Mainboard Unbricking (24C32, 24C64)

    Problem: A corrupt EDID or user storage causes "no boot."
    Solution: In-circuit programming is required. Neo 2.1.0.19’s I2C scanner identifies the device address even when multiple devices are on the bus (e.g., 0x50, 0x51). The "Stop I2C bus" command releases the bus after programming, which avoids hanging the TV’s main processor—a feature broken in v2.2.x. Neo Programmer 2.1.0.19 BEST
