Xiaomi Mi 11 Lite 5g - Não liga (Análise e Diagnóstico)

📱 Xiaomi Mi 11 Lite WON'T TURN ON — Quick and straightforward diagnosis (real-life bench case) In this video, I show a straightforward step-by-step process to solve the "won't turn on" problem without guesswork: ✅ Primary lines (present just by connecting the battery/power supply) ✅ VBAT (≈ 3.7–4.4V) and GND as a reference for all measurements ✅ VBUS (≈ 5V) passing through the OVP protection before the charging IC ✅ IF PMIC (charging IC): power path, protection, and measurement (when it fails, it causes erratic charging/strange consumption/overheating) ✅ VSYS / VPH_PWR (main system line): if it doesn't appear, the device won't turn on 🎯 The idea here is: measure correctly, find the problem quickly. 👉 Set a reminder, like the video, and join the live stream. Those who understand the process will be able to handle the repair. 🔧📱 📄 Supporting material: I will be using the A52 5G Charging Protocol PDF during the live stream. 📌 VIP group link: https://chat.whatsapp.com/D8F2ufAa4L8... 📲 Follow me too: 📸 Instagram: @ricardo_tecnopro 🎥 TikTok: @prof.ricardoestevam #cellphonetechnician #cellphoneassistance
