Team Tekno World ke free mobile repairing course mein aapka swagat hai! Main hoon Rakesh Chauhan, aur yeh humara Lesson 29 hai.
Pichle lesson mein humne Combo (Screen) badalne ki kala seekhi thi. Aaj hum ek aise component ki baat karenge jo “dikhayi” nahi deta, lekin “mehsoos” hota hai: Vibration Motor. To aaj baat hone wali hai Mobile Vibration Not Working Solution ke baare mein.
Sochiye aap meeting mein baithe hain aur phone silent par hai. Agar vibration kharab hai, toh zaroori call miss ho jayegi. Gamers ke liye, agar Haptic Feedback (Goli chalne par jhatka lagna) kaam na kare, toh game ka aadha maza khatam ho jaata hai.
Grahak ki shikayat:
- “Bhaiya, call aati hai toh phone hilta (vibrate) nahi hai.”
- “Vibration bahut dheemi (Weak) ho gayi hai, awaaz zyada kar raha hai par jhatka kam hai.”
- “Type karte waqt ‘tik-tik’ (Haptics) band ho gaya hai.”
Aaj hum seekhenge Mobile Vibration Not Working Solution, motor ke types, aur motherboard diagnosis.
Step 1: Types of Motors (Pehchan Zaroori Hai)
Repair shuru karne se pehle, aapko pata hona chahiye ki phone mein kaunsi motor lagi hai. Yeh 2 tarah ki hoti hain:
1. ERM Motor (Coin / Button Type):
- Dikhne mein: Gol (Round), ghadi ki battery jaisi.
- Kaam: Yeh ghoomti hai (Rotate). Iske andar ek wajan (weight) hota hai jo ghoomne par phone ko hilata hai.
- Kahan milti hai: Purane Android phones aur Keypad phones mein. Ismein 2 taar (Red/Blue) ya spring contact hote hain.
2. LRA Motor (Linear Resonant Actuator):
- Dikhne mein: Chokor (Square/Rectangular), metal body jaisi.
- Kaam: Yeh ghoomti nahi hai, balki spring ki tarah upar-neeche “Oscillate” karti hai. Iska vibration bahut sharp, tez aur crisp hota hai.
- Kahan milti hai: iPhone (Taptic Engine), OnePlus, Samsung S-Series aur naye 5G phones mein.
Step 2: Software & Settings Check
Phone kholne se pehle, confirm karein ki galti user ki hai ya hardware ki.
- Sound Settings:
Settings > Sound & Vibrationcheck karein.- Kya “Vibrate on Silent” ON hai?
- Kya “Haptic Feedback” level zero toh nahi hai?
- Diagnostic Code (Ram Baan):
- Samsung: Dial
*#0*#> Click Vibration. - Xiaomi/Redmi: Dial
*#*#6484#*#*> Vibration Test. - Result: Agar test mein phone vibrate hua, toh motor 100% theek hai. Galti software/settings mein hai (Reset karein). Agar nahi hua, toh phone kholein.
- Samsung: Dial
Step 3: Physical Contact (Sabse Common Fault)
Mera experience kehta hai ki 70% cases mein motor kharab nahi hoti, bas uska Connection Loose hota hai.
- Carbon/Rust: Motor motherboard se Spring Contacts ke zariye judi hoti hai. Wahan aksar kaala carbon ya paani ka corrosion aa jaata hai.
- Solution: Ek Eraser (Rubber) ya Fiberglass Pen se motherboard ke golden tips aur motor ke springs ko chamka dein.
- Lift Pins: Agar spring dab gaye hain, toh chimti (tweezer) se unhein thoda upar utha dein taaki wo board ko kass kar pakdein.
Step 4: Motor Testing (Cold Testing – Ohm Value)
Agar safai ke baad bhi nahi chala, toh Multimeter uthayein aur motor check karein.
- Mode: Multimeter ko 200 Ohm (Ω) par set karein.
- Process: Motor ko board se alag karein aur dono points par probes lagayein.
| Motor Type | Normal Reading (Ohm) | Faulty Condition |
| Coin (Gol) | 10 Ω se 70 Ω | 0 Ω (Short) ya 1 / OL (Open/Wire break) |
| Linear (LRA) | 8 Ω se 30 Ω | 0 Ω (Short) ya 1 / OL (Coil Open) |
- Faisla: Agar reading ‘1’ (OL) hai, toh motor ke andar ki coil toot gayi hai. Replace karein.
Step 5: Voltage Check (Hot Testing – Circuit Fault)
Agar Motor ki Ohm value theek hai, fir bhi vibrate nahi ho raha? Iska matlab Motherboard se current nahi aa raha.
- Phone ON karein aur
*#0*#se Vibration Test chalu chhod dein. - Multimeter ko DC 20V par set karein.
- Motherboard ke VIB+ aur VIB- tips par voltage check karein.
Logic Samjhein:
- Vibration lagatar nahi hota, wo “Ghurr-Ghurr” karta hai. Isliye Voltage bhi Fluctuate (Pulse) karega.
- Reading: 1.0V se 3.0V ke beech reading upar-neeche honi chahiye.
- Result:
- Voltage OK: Agar voltage aa raha hai par motor nahi hili = Motor Kharab.
- Voltage 0V: Power IC ya Driver IC se supply nahi aa rahi.
Step 6: Vibration Driver IC (Advance Knowledge)
Saste phones mein Vibration ka voltage seedha Power IC se aata hai.
Lekin mehenge phones (jaise iPhone ya Gaming Phones) mein LRA Motor ko chalane ke liye ek alag se choti “Haptic Driver IC” hoti hai.
- Trace: Agar voltage nahi aa raha, toh Schematic mein dekhein ki VIB line kahan se aa rahi hai.
- Series Component: Raste mein ek Chota Coil ya 0 Ohm Resistor laga hota hai. Agar wo open ho gaya hai, toh Jumper maar dein.
Summary Checklist
- Code Check:
*#0*#se test karein. - Clean Contacts: Golden tips par carbon saaf karein (Most Important).
- Ohm Test: Motor ki value 8-70 Ohms ke beech honi chahiye.
- Voltage: Tips par fluctuating voltage (1V-3V) aana chahiye.
- Fitting: Motor loose nahi honi chahiye, tape se chipkayein.
💡 Aaj Ka Aapka Task – Lesson 29 (Comments & Forum)
- Practical: Apne multimeter se kisi bhi vibrating motor (purane phone ki) ki Ohm Value check karke comment mein likhein.
- Comment (नीचे): Kya aapne kabhi dekha hai ki motor loose hone par phone “Phata hua speaker” jaisi awaaz karta hai? Yes/No likhein.
- Forum: Agar VIB ke tracks motherboard se ukhad gaye hain, toh jumper solution ke liye Forum (forum.teamtw.in) par board ka photo daalein.
Agla Lesson: Vibration fix ho gaya! Ab hum us topic par aayenge jo sequence mein agla hai. Agla lesson hai: “Lesson 30: SIM Card Not Detecting Solution”।
