| Symptoms | Disposal Methods |
|---|---|
| 1. Blank screen / Power indicator does not work | Check whether the power supply is in good contact with the display and the power socket; and check whether the display is turned off. |

| 3. Display overheating | Leave at least 10cm of ventilated space around the display. Do not place articles on the display. |
| 4. Dark/light spots when powered on | This is normal. Due to temperature differences, the backlit tube may emit uneven light initially. It will normalize after about 20 minutes, and spots will be eliminated. |
| 5. Image distortion, flashing, shaking | Check your computer configuration, choose the correct resolution, and reset your refresh rate. If the PC video signal exceeds the display's frequency range, the display will disable signals for protection. Set the PC output frequency to an acceptable range. |
| 6. Noisy signal when powered off | During power-off, some noisy signals may appear on the screen due to normal discharge. This is normal. |
