Warranty and Repair Procedures

Warranty and repair work will be carried out according to the terms of the contract, the manufacturer's and contractor’s procedures, the client’s requirements, and the technical standards of the equipment. All standards and technical specifications will comply with the manufacturer’s recommendations, relevant industry regulations, and applicable standards/norms.

Rapid Response to Requests
Upon receiving a request from the client or the end user, the warranty department will quickly implement troubleshooting measures according to the following process:

Step 1: Contact the Point of Contact
Immediately contact the point of contact at the user’s side to gather detailed information about the system issue.

Step 2: Remote Troubleshooting
Coordinate with the operator and the personnel using the equipment to inspect and diagnose the issue remotely using tools like phones, smartphones, video calls, TeamViewer, Ultraview, and other flexible tools.
If the issue is identified, both parties will work together to resolve it. If the issue cannot be fixed immediately, a temporary solution will be implemented until a technician can arrive on-site to handle it.

Step 3: On-Site Troubleshooting
Warranty staff will visit the location to inspect, document, and perform necessary actions, including taking photos and videos to record the situation.

The troubleshooting steps will follow the maintenance and service procedures outlined below:

Cold Check:

1. Disconnect the power and signal from the LED screen system.

2. Inspect and ensure the stability of the steel frame and the structures used for installation.

3. Check and handle the power and signal connection pins, ensuring no loose connections or pin failures.

4. Inspect the flatness of the modules and cabinets.

5. Examine other components of the system, including the control board, cables, power supply, network cables, and accessories.

6. Check and measure the ground resistance of the system and grounding wires.

7. Clean the entire LED screen system following the manufacturer’s procedures.

Hot Check:

1. Power the system and signal, ensuring the content displayed is as agreed upon and approved by the client.

2. Inspect the condition of the power cabinet, power supply, and power input points.

3. Check status indicator lights and alarm devices on the LED screen.

4. Measure and check electrical parameters of the system, including current, voltage, frequency, and power consumption.

5. Inspect the screen’s brightness, glare, viewing angle, and other technical parameters.

6. Check the operating temperature and cooling system of the entire system.

7. Inspect and evaluate the modules, cabinets, and other related devices.

8. Verify the management and control software of the LED screen, as well as the configuration backup files.

If any abnormalities are detected, they will be recorded in the maintenance log and reported to the client and user. If an issue is identified, the staff will take immediate action. Faulty devices will be repaired or replaced to ensure the system operates stably.

In case the equipment needs to be taken back for repair or sent to the manufacturer, a detailed handover report will be prepared.

If the fault is determined to be the manufacturer’s responsibility, the contractor will carry out repairs, replacements, or provide a new product as stipulated in the contract.

In the case the fault is caused by the end user, the contractor will provide a temporary replacement to ensure the system continues to function, and negotiations with the client will occur to determine a solution.

All maintenance, servicing, warranty, and troubleshooting data will be carefully stored in technical records to provide the best possible service for each customer.
