| Problem | Possible Cause(s) | Solution | | :--- | :--- | :--- | | | Wrong firmware flashed; Panel voltage issue. | Re-flash with the correct firmware; double-check panel voltage. The board may have defaulted to a generic setting after an update. | | Board Unresponsive / Bricked | Incorrect firmware; Power interruption during flash. | Use a hardware programmer (e.g., CH341A) to flash the correct firmware directly onto the SPI flash chip (like the 25Q32). | | No Signal on HDMI/VGA | Incorrect input source selected; Signal compatibility issue. | Use the remote or button board to cycle through input sources (HDMI1, VGA, AV, etc.). | | No Backlight / Dark Screen | LVDS cable connection; Backlight enable/inverter issue. | Check the LVDS cable connections and continuity. Verify the "ON" pin is connected to the backlight's enable line; the board may not output it if not configured. | | Buttons Not Working Properly | Wrong key mapping in the firmware; Hardware button mismatch. | Re-flash with a firmware explicitly matching your button layout (e.g., "7key" vs "5key"), or rewire the keypad. The community can help with mapping issues. |
