Galat diagnosis = galat repair = nuksan.
Aaj ka blog aapko batayega ke ek mobile ko technical tarike se test kaise kiya jata hai, takay repair pehle attempt mein successful ho.

🔍 1. User Complaint Ko Gaur Se Samajhna – “Suno Jo Phone Keh Raha Hai”

Repair ka pehla step hai symptoms ko samajhna:

• Phone charge nahi ho raha? To charger, port, ya battery problem ho sakta hai.
• Phone vibrate karta hai lekin display nahi dikhta? To ya to LCD kharab hai ya backlight IC.
• Network signal nahi aata? To antenna ya network IC pe masla ho sakta hai.
• Touch kaam nahi kar raha? Ho sakta hai digitizer ya connector mein problem ho.

👂 Pehle “phone ka bayan” suno — fir tools uthao.

🧪 2. Primary Testing – Basic Se Start Lo, Advance Tak Jao

Sabse pehle simple cheezein test karo:

• Charging port check karo – kya loose to nahi?
• Different charger/cable lagao – faulty cable ka chance hota hai.
• Battery swelling check karo – puffed battery ko turant replace karo.
• Visual inspection – koi IC jali hui, burnt ya color change?

Yeh sab visual aur basic checks aapke kaam ko 30% asaan kar dete hain.

🧰 3. Tools Use Karna Seekho – Professional Bano

Tools = Technician ki aankhein
Aap ko ye zaroori tools use karne aane chahiyein:

• Multimeter: PCB track, voltage aur continuity test
• DC Power Supply: Dead phones ke current draw check karne ke liye
• Magnifier Lamp / Microscope: Chhoti cracks ya damage dhoondhne ke liye
• Thermal camera ya IPA spray: Heating components identify karne ke liye

🔧 Ye tools sirf show-off nahi, har problem ka asar inhi se pakda jata hai.

💻 4. Software Glitches Ko Ignore Mat Karo

Har issue hardware ka nahi hota. Software bhi major reason hota hai:

• Lagging – Factory reset ya cache clean
• Stuck on logo – Flashing
• Auto restart – Software bugs or battery profile issue
• No charging logo – Calibration error

Pehle software fix karke dekho, agar na ho to hardware pe jao.

🧠 5. Logical Troubleshooting – Andazay Nahi, Reasoning Chahiye

Har maslay ka ek logic hota hai.
Example:

• Agar charging IC short ho toh board pe excessive heat aayegi.
• Agar display on hai magar no light, toh backlight section check karo.
• Agar voltage supply aa rahi hai magar output nahi, toh capacitor ya coil test karo.

Jis area mein masla ho, usko isolate karo.

🧯 6. Mistakes Jo New Technicians Karte Hain

❌ Bina tools ke kaam karna
❌ Har baar flashing se shuru karna
❌ IC guess kar ke hi replace kar dena
❌ User complaint ko ignore karna
❌ “Sab kuch try kar liya” keh ke give up kar dena

🎯 Technician woh hota hai jo har baar logic se kaam kare, andaza se nahi.

📌 7. Pro Tips – Experts Se Seekhe Gaye Golden Rules

✅ Hamesha ESD protection lo (anti-static mat & wrist band)
✅ Dummy board pe pehle practice karo
✅ Component replacement ke baad full board test zaroor karo
✅ Har section ka voltage chart ya schematic diagram samjho
✅ Har problem ko document karo – yeh future mein kaam aayega
