💀 Dead Phone – Sirf Off Ya Kuch Aur?
Jab mobile bilkul on nahi ho raha, na charging ka signal, na logo, na vibration – toh user confuse ho jata hai ke kya phone sirf off hai ya completely dead?
Dead phone ka matlab hota hai:
Mobile kisi bhi button, charger ya action ka response nahi deta – na display, na sound, na charging.
Lekin khushkhabri yeh hai: Aksar dead phones repair ho sakte hain – bas aapko sahi diagnosis aur tools ki zarurat hoti hai!
🔧 Step-by-Step Dead Phone Diagnosis
1️⃣ Battery Check Karein
- Voltmeter se battery voltage check karein (3.7V hona chahiye)
- Dummy/test battery lagaa kar try karein
- Bulged battery ya leak dikh raha ho toh replace karein
📌 Pro Tip: Agar battery normal hai lekin phone dead hai, toh agla step motherboard inspection hai.
2️⃣ Charger & Cable Check
- Naya charger aur USB cable use kar ke check karein
- Computer se connect kar ke dekhein kya phone detect ho raha hai?
- Charging jack ko torch se inspect karein – damage/dust ho sakta hai
3️⃣ Dead Mobile Phone ka Multimeter SE Voltage Test (PCB)</h3>
- Battery connector points par voltage check karein
- Power IC, Charging IC aur Fuse area par continuity check karein

⚡ Dead Phone Flashing Se Zinda?
Kabhi kabhi phone dead dikhta hai lekin bootloader ya EDL (Emergency Download Mode) active hota hai.
🛠 Tools:
- SP Flash Tool (MediaTek phones)
- Mi Flash Tool (Xiaomi)
- UMT / Miracle Box
- QFIL Tool (Qualcomm phones)
📌 Pro Tip: Phone connect ho raha ho PC mein (sound aaye) toh software level par problem ho sakta hai – flashing se fix ho jaata hai!
🔒 Boot Key Aur Test Point Se Boot Karna
Agar phone EDL mein nahi ja raha:
- Test points short karein (PCB pe mark hota hai)
- Ya phir boot key press karke PC se connect karein
- EDL cable bhi ek option hai
🧠 Yeh kaam expert level ka hota hai – agar aap beginner hain toh pehle training lein.
🛑 Kab Replace Karna Behtar Hai?
Har phone repairable nahi hota. Agar:
- PCB burn ho gaya ho
- ICs melt ho chuki ho
- Multilayer track damage ho
Toh replacement hi sahi option hoti hai.
🔐 Safety Tips:
- PCB ko overheat na karein
- ESD strap use karein static se bachne ke liye
- Customer data secure rakhna na bhoolein
- Tools sirf professional quality wale use karein
