Simple Troubleshooting
| Symptom | Troubleshooting Methods |
|---|---|
| 1. Black screen / Power indicator not working | Check if the power supply is properly connected to the screen and the power outlet. Verify if the screen is turned on. |
| 2. Blurry images, too large or too small | Access the "Image Settings" menu and select "Auto Image Adjustment" for automatic monitor correction (VGA monitors only). |
| 3. Dark screen | Access the "Brightness and Contrast" menu to adjust screen contrast and brightness. |
| 4. Screen overheating | Ensure at least 10cm of ventilated space around the screen. Do not place objects on top of the screen. |
| 5. Dark/light spots when powered on | This is normal due to temperature differences. The backlight will stabilize and eliminate spots after about 20 minutes of operation. |
| 6. Image distortion, flickering, or jittering | Check your computer's configuration, select the correct resolution, and reset the refresh rate. |
| 7. Noisy signal when powered off | Some screen noise may occur during power-off due to normal discharge. |

Important Safety Precautions
- Read all instructions carefully before using the product.
- Disconnect the power cord before cleaning. Use a soft, damp cloth; avoid liquid or spray cleaners. For stubborn stains, use an LCD screen cleaner.
- Do not use accessories not recommended by the manufacturer.
- When unplugging the power cord or adapter, grasp the plug, not the cord itself.
- Keep the display away from water sources (e.g., bathtubs, sinks, pools). Do not place on wet floors. Avoid pressing the LCD screen with fingers or hard objects.
- The slots and openings in the casing are for ventilation. Do not block them by placing the display on beds, sofas, or carpets. Avoid placing near radiators or heaters. Do not place in enclosed spaces without adequate ventilation.
- Use only the power supply type indicated on the rating label. Consult your dealer or local power administration if unsure.
- The power cord may have a three-pin plug for grounding. Ensure it is used with a properly grounded outlet. If not, contact an electrician to replace the outlet.
- Do not attempt to repair the display yourself. Refer servicing to qualified personnel.
- Unplug the power cord and contact qualified service personnel if: the power cord or plug is damaged; the display has been dropped or the casing is damaged; or the display shows obvious abnormalities requiring service.
- Place the display in a well-ventilated area, away from strong light, high temperatures, or humidity.
