In this video, we dive deep into an iPhone 14 Pro Max charging issue that required a motherboard repair. The phone wasn’t charging due to a problem with the lightning controller IC and Yangtze Charger Controller IC. After performing diagnostics with a dock tester and multimeter, we identified a faulty resistor between the two ICs causing an open line. Watch as we carefully disassemble the motherboard, replace the defective components, and bring this iPhone back to life with a successful charge!
