Common Mobile Phone PCB Issues and How to Troubleshoot Them
Many PCB failures occur due to water exposure, excessive heat, improper charging adapters, power surges, or accidental impact. Common issues include power IC failure, display not turning on, no charging, auto-restart, Wi-Fi not functioning, baseband failure, touch unresponsiveness, dead boot loop, battery sensor issues, and speaker or audio IC malfunction.
Troubleshooting starts with continuity testing, checking shorted capacitors, cleaning PCB corrosion with ultrasonic treatment, replacing damaged IC chips, reflowing solder joints, BIOS flashing, and mainboard reballing.
