Diagnostic & Repair Protocol
Phase 1 — Initial Diagnosis
| Check Point | Expected Result | Action if Failed |
| Standby LED | Red LED ON | Check power supply 5VSB rail & fuse |
| Main 12V Rail | 12.0V ±0.5V | Replace PSU or check capacitors |
| 3.3V SPI Supply | 3.3V steady | Check LDO regulator near SPI chip |
| Boot Process | Logo appears within 8 sec | Firmware reflash required |
| 25Q64 Chip ID | Read via RT809H: EF 40 17 | Replace chip if ID unreadable |
| Panel Voltage | DTW400LL01-D: LVDS signal present | Check TCON connector & cables |
Phase 2 — SPI Firmware Reflash Procedure
Install the latest RT809H software on your PC. Connect the programmer via USB and verify device detection in the software interface.
Disconnect mains power completely. Locate the 25Q64 SPI flash chip on the T.SIS231.81 main board. Refer to the SPI chip image below for exact location.
Attach the RT809H SOIC8 clip directly to the 25Q64 chip while still on the board. Ensure pin 1 orientation is correct (marked dot on chip).
Before writing, always perform a Read operation to save the original firmware as a backup. Select chip: W25Q64 in the RT809H software.
Load the downloaded .BIN firmware file. Execute Erase → Blank Check → Program → Verify sequence. Do not interrupt the process.
Remove the SOIC8 clip, reconnect the TV power cable, and power on. TV should boot normally within 10–15 seconds.
