Phone Garam Kyo Hota Hai?: Overheating Problem Solution (100% Fix) | Lesson 18

Team Tekno World ke free mobile repairing course mein aapka swagat hai! Main hoon Rakesh Chauhan, aur yeh humara Lesson 18 – Overheating Problem Solution: Phone Garam Kyo Hota Hai? (100% Fix) hai.

Pichle lesson (Lesson 17) mein humne “Battery Drain” seekha tha. Aaj hum uske judwa bhai “Overheating” (Garam hona) ke baare mein baat karenge.

Grahak ki shikayat: “Bhaiya, game khelte waqt phone aag jaisa tapta hai” ya “Jeb mein rakhe-rakhe garam ho raha hai.”

Ek technician ke taur par aapko samajhna hoga ki “Garam” (Warm) hona normal hai, lekin “Tapna” (Overheat) hona beemari hai. Aaj hum seekhenge ki Shorting aur CPU Paste ki wajah se hone wali heating ko kaise theek karein.

Step 1: Normal vs. Abnormal Heating (Pehchan)

Sabse pehle grahak se puchein ki phone kab garam hota hai?

1. Normal Heating: Agar charging ke waqt, heavy gaming (PUBG/BGMI) ke waqt, ya video recording ke waqt phone garam ho raha hai, toh yeh Normal hai. (Bas background apps band karein).
2. Abnormal Heating: Agar phone bina use kiye (Idle) garam ho raha hai, ya call karte hi kaan jalne lagta hai, toh yeh Hardware Fault hai.

Step 2: Hardware Check (Shorting Diagnosis)

Agar phone abnormal garam ho raha hai, toh 90% chance hai ki motherboard mein “Leakage” (Half Shorting) hai.

• Action: Phone ko DC Power Supply (Lesson 13) se connect karein (OFF condition mein).
• Check: Kya machine 0.000 ke bajaye 0.050 – 0.200 Ampere le rahi hai?
• Result: Agar haan, toh board par koi component (Capacitor/IC) short hai jo battery ki power ko “Garmi” (Heat) mein badal raha hai.

Step 3: Garam Hissa Kaise Dhoondhe? (Thermal Camera)

Shorting dhundhne ka sabse professional tareeka Thermal Camera hai.

• Thermal Camera Kya Karta Hai? Yeh board par maujood electric potential (voltage) aur heat ko dekh sakta hai. Jaisa ki aap upar image mein dekh sakte hain, jahan zyada voltage/current rukta hai (Shorting), wahan ka hissa Laal (Red/White) ho jata hai aur baaki hissa Neela (Blue) rehta hai.

Sasta Tareeka (Rosin Smoke):

Agar Thermal Camera nahi hai, toh Rosin Smoke (Lesson 40) use karein. Short component sabse pehle pighlega.

Step 4: CPU Heating (Thermal Paste) – [Pro Tip]

Agar phone short nahi hai (DC Reading 0.00 hai), lekin game khelte hi CPU bahut zyada garam ho jaata hai aur phone Hang/Restart hone lagta hai, toh samasya “Thermal Paste” ki hai.

Kyon? CPU (Central Processing Unit) kaam karte waqt garam hota hai. Us garmi ko hatane ke liye uske upar Heat Sink (Metal Shield/Tape) laga hota hai. In dono ke beech ek Paste hota hai jo garmi ko CPU se kheench kar Heat Sink tak bhe jta hai.

Jab yeh paste sookh (dry) jaata hai, toh CPU cool nahi ho paata aur phone garam hone lagta hai.

Solution (Fix):

1. SMD se CPU ke upar ki steel shield hataye.
2. Purana sookha hua paste saaf karein (IPA se).
3. Achhi quality ka naya Thermal Paste (Grey wala – jo computer CPU par lagta hai) lagaye.
4. Waapas pack karein. Phone bilkul thanda chalega aur performance badh jayegi.

Summary Checklist

1. Diagnosis: Kab garam hota hai? (Idle = Shorting, Gaming = CPU).
2. Shorting: DC Machine aur Thermal Camera/Rosin se garam component nikaale.
3. CPU: Agar gaming mein garam hai, toh Thermal Paste badlein taaki Heat Sink sahi kaam kare.

💡 Aaj Ka Aapka Task – Lesson 18 (Comments & Forum)

1. Practical: Apne phone par koi heavy game 10 minute khele aur dekhein ki garmi kahan se aa rahi hai? (Note: CPU hamesha camera ke paas hota hai).
2. Comment (नीचे): Kya aapne kabhi mobile mein “Thermal Paste” badla hai? Yes/No likhe.
3. Forum: Agar aapke paas koi aisa phone hai jo garam hokar band ho jaata hai, toh humare Forum (forum.teamtw.in) par model number bataye.

Agla Lesson: Ab aag (Heat) bujha di! Ab hum “Paani” (Water) se ladenge. Agla lesson hai: “Lesson 19: Water Damage Repair (Paani mein gire phone ko kaise bachayein?)”।
