🔍 Quick diagnosis of fault types
• Dynamic stripes: Color changes when the screen is lightly shaken/tilted, often due to poor cable contact (dropping/water ingress/aging models)
Fixed stripes: colored vertical lines/black spots with fixed positions, which may be caused by liquid crystal layer rupture or screen burn-in
• Touch abnormality: Striped area accompanied by broken touch/no response, be alert to cable breakage or touch layer damage

🛠️ Five minute self inspection process
one ️ Physical inspection
Lightly press the four corner border: If the stripes become lighter, it indicates loose wiring. You can use an alcohol swab to clean the gaps
Pure black wallpaper test: OLED burn-in displays fixed residual images, with clear linear physical damage
External display verification: Connect the monitor through the acquisition card/docking station to distinguish between screen or motherboard faults
two ️⃣ Scenario based judgment
Sudden malfunction after use in low-temperature environment: temperature difference causes cable contraction
Stripe flicker during charging: prioritize troubleshooting power chips or data cables
Post game screen flickering: GPU overheating and high possibility of virtual soldering
💡 Hierarchical solution
▶ Cable contact issue
Emergency response: Clean the eraser charging port, restart and observe
Thoroughly repaired: Professional disassembly and re insertion of ribbon cables (50-150 yuan), recommended full supervision throughout the process
▶ Screen damage disposal
LCD leakage: Edge color spot diffusion requires replacement of the assembly screen, priority should be given to official after-sales service
OLED burn-in: Developer mode resets screen calibration to avoid long-term static high brightness images
▶ Mainboard level malfunction
GPU virtual soldering: sent for repair within the warranty period, non warranty devices can try to use it with reduced frequency
Abnormal power chip: Replace MFi certified data cable and investigate charging module
