【Essential Tips for Mobile Screen Repair】A Must-Read for Repair Shop Owners!

I. Pre-repair Inspection

• Thorough Diagnosis: Don't rush to start. First, carefully inspect the screen issue. Is it cracked, flickering, or unresponsive? Pay attention to every detail to ensure an accurate diagnosis and avoid unnecessary repairs.
• Check Other Components: Sometimes, screen issues are just the tip of the iceberg. Internal flex cables or the motherboard might also be faulty. Don't forget to check these potential "culprits" to prevent new problems after the repair.

II. Choosing the Right Components

• Quality First: Good components are the key to successful repairs! Try to choose branded parts. Although they might be a bit more expensive, their quality is guaranteed. Don't cut corners on cost and risk having customers come back for re-repairs.
• Compatibility Check: Once you have the parts, carefully verify the model to ensure they perfectly match the customer's phone. Avoid the headache of mismatched components that can ruin your reputation.

III. Attention to Detail During Repair

• Electrostatic Protection: During repairs, static electricity can "kill" the chips inside the phone in an instant. Remember to wear an anti-static wristband and ensure your workbench is clean and free from static hazards.
• Handle with Care: Screens are fragile. When disassembling and reassembling, be gentle. Don't let "rough handling" cause secondary damage to the screen, increasing repair costs.
• Flex Cable Connection: This is where problems often occur! Make sure the flex cable is securely inserted and that the gold fingers are wiped clean. Don't let a small oversight cause the customer's phone to become unresponsive.
• Screen Calibration: After replacing the screen, don't forget to calibrate the touch screen. Ensure the screen's sensitivity and accuracy so that customers have a smooth experience.

IV. Post-repair Testing

• Function Testing: After the repair, don't hand it over immediately. First, test the screen display, touch, buttons, and other functions to ensure everything is working properly before giving it back to the customer.
• High-Temperature Testing: If possible, conduct a "high-temperature test" to see if the screen has any issues under high temperatures. This is the "gold standard" for testing screen quality.

V. Communication with Customers

• Clear Explanation: Before the repair, explain the problem and repair plan in detail to the customer. Don't leave them confused. After the repair, also clarify the repair process and precautions to put the customer at ease.
• Provide Warranty: Offering a warranty to customers not only builds trust but also reduces potential disputes. Don't underestimate this small "warranty"—it's a powerful tool for improving your reputation.

VI. After-sales and Re-repair

• Quick Response: If a customer has an issue, respond immediately. Don't keep them waiting. Patience and efficiency are key to retaining customers.
• Re-repair Handling: If a customer returns for re-repair, never be perfunctory. Carefully inspect the problem and repair it for free to show your sincerity.
