🛠️ Diagnostic & Repair Protocol
- Power Diagnosis: Confirm standby voltage (3.3V/5V) at SPI chip before attempting read/write.
- Clip Connection: Use SOIC-8 test clip. Ensure pins 1-8 aligned correctly. Double-check continuity.
- Read Original: Always read and save original dump before flashing. Verify checksum.
- Write Enable: In RT809H software, disable Write Protection via “WP” pin control or software command.
- Erase → Program → Verify: Full chip erase → Load .bin file → Write → VERIFY CHECKSUM. Never skip verify.
- Post-Flash Test: Reconnect board, power on without panel first. Check LED blink codes or backlight trigger.
- Failure Handling: If TV dead after flash: re-read chip, compare against original backup. Reflash if mismatched.
