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 remains a staple tool for a reason: it works. By paying close attention to your COM port settings and configuration bits, you can reliably program thousands of Microchip PICs without issue. Keep this version in your toolbox—it’s often faster and more reliable than modern "bloatware" alternatives. Neo Programmer 2.1.0.19 BEST
Note: Always ensure you have the correct firmware update file for your specific programmer hardware before attempting software updates. Problem: A corrupt EDID or user storage causes "no boot
Later versions (2.2.x.x and above) have been reported to crash when programming large 25Q series flash chips (e.g., 25Q256, 25Q512). Version 2.1.0.19, however, handles buffers up to 64MB without memory leaks. It can run for 8+ hours of continuous programming in a production environment without a single "Device not responding" error. Note: Always ensure you have the correct firmware
Let's break down the specific features that make this version a powerhouse:
| Version | Stability | Chip Support | BIOS Fixes | |---------|-----------|--------------|-------------| | 2.1.0.19 (BEST) | ⭐⭐⭐⭐⭐ | 600+ | Full | | 2.2.0.x | ⭐⭐⭐ | 700+ | Partial | | 1.0.x | ⭐⭐ | ~200 | None |
2.1.0.19 remains best for BIOS repair & CH341A despite newer versions.
