| Issue | Probable Cause | Solution |
| :--- | :--- | :--- |
| Screen is White / Backlight On, No Picture | Wrong Firmware version or LVDS cable loose. | Re-seat the LVDS cable. Check if the firmware matches the specific panel resolution (e.g., 1080P vs 4K). |
| Logo Appears, then Reboots Loop | Corrupted bootloader or incomplete flash. | Use the CH341A Programmer method. USB upgrade is failing to overwrite the bad sectors. |
| Screen Colors Inverted (Negative Image) | Wrong LVDS Map in firmware settings. | Enter Service Menu (Menu + 1147) -> Panel Setting -> Change LVDS Map from JEIDA to VESA (or vice versa). |
| USB Drive Not Detected | USB format incorrect or port damaged. | Ensure USB is <32GB and formatted as FAT32. Try the USB port on the side or back (some boards have dedicated service ports). |
