Alim stabilisée diagnostic | Économiser des heures de réparation

When an iPhone won't start, should you replace parts randomly, or is there a faster way to diagnose the problem? In this video, I'll show you how to use a lab power supply (regulated power supply) to interpret an iPhone's power consumption and get valuable information before even disassembling the motherboard. We'll cover: how to properly adjust a regulated power supply; how to recognize a short circuit; how to interpret different power consumption readings; why high power consumption doesn't always indicate the same problem; and how to avoid further damaging the motherboard during diagnosis. The demonstrations are performed on two iPhone XR models: one working and one with a short circuit on the motherboard. This method is used daily in our workshop for diagnosing Apple motherboards. 👉 At SoroS Repair, we specialize in: • Apple motherboard repair • Advanced electronic diagnostics • Microsoldering • Data recovery • MacBook, iPhone, and iPad repair 🌐 https://sorosreparation.fr 📺 More videos on the channel: MacBook won't start Apple motherboard repair Microsoldering Electronic diagnostics #Chapters 00:00 Introduction: Why use a regulated power supply? 00:21 Demonstration Objective 00:46 Introduction to the Lab Power Supply 01:34 Adjusting Voltage and Current Limiting 02:24 Simulating a Short Circuit 03:13 Different Diagnostic Cables for iPhones 04:42 My Favorite Adapter: Qianli iPower Max 05:39 Diagnostics with a USB Multimeter 06:44 Example of a Working iPhone 07:12 Example of an iPhone That Won't Start 08:53 Normal Behavior on a Regulated Power Supply 09:16 Detecting a Short Circuit on the Motherboard 10:47 Important Tips Before Applying Voltage 12:26 How to Interpret Different Power Consumption Levels 14:45 Conclusion 🛠 Tools Used in this Video ▶ Siglent Regulated Power Supply: https://tinyurl.com/spd3303x ▶ Entry-Level Regulated Power Supply : https://tinyurl.com/alimstab ▶ Qianli iPower Max Adapter (new version): https://s.click.aliexpress.com/e/_c3f... ▶ Sunshine Adapter: https://s.click.aliexpress.com/e/_c3E... ▶ USB-C Multimeter: https://s.click.aliexpress.com/e/_c2x... ▶ USB Multimeter with Graph: https://s.click.aliexpress.com/e/_c2y... ▶ Qianli Thermal Camera: https://s.click.aliexpress.com/e/_c4m... ▶ Entry-Level Thermal Camera: https://tinyurl.com/camterm ▶ Microscope: https://tinyurl.com/microscope4T My Tools: iPhone Screwdriver: Qianli Thor: https://amzn.to/4kiNFVy Wera Pentalobe: https://amzn.to/3HeTSxn Fluke Multimeter: https://amzn.to/4atSfMf Quick Hot Air Station: https://amzn.to/4q8pb2i MacBook Screwdrivers: Suction Cup for MacBook Back Cover (2016 onwards): https://amzn.to/3raEFry Wera Torx T3: https://amzn.to/3Gd9vnF Wera Torx T5: https://amzn.to/34k4aOe Wera Security Torx 8: https://amzn.to/3GbRmGD Wera Pentalobe: https://amzn.to/32IcA1d JBC Precision Soldering Station CD-2BQF on Amazon: https://amzn.to/4rmeSsq The JBC soldering station that I'm currently using: JBC DMPVE-2QA Rework Station: https://amzn.to/3BSuaNE My favorite iFixit kit: https://amzn.to/4tbsqJ2 Discover our community dedicated to Apple device issues! 💻🍎 Join our Facebook group "Apple Troubleshooting" to share your problems and get help.
