Team Tekno World ke free mobile repairing course mein aapka swagat hai! Main hoon Rakesh Chauhan, aur yeh humara Lesson 28 hai.
Aaj hum mobile repairing business ki “Backbone” (Reedh ki Haddi) yaani Mobile screen replacement ki baat karenge.
Ye sabse zyada paisa dene wala kaam hai, lekin agar fitting sahi na ho, toh customer wapas aata hai shikayat lekar: “Light bahar dikh rahi hai” ya “Touch apne aap chal raha hai.”
Aaj hum seekhenge Mobile screen replacement karne ka wo professional tareeka jo service center wale use karte hain.
Step 1: Pre-Installation Testing (Warranty Bachao)
Naye folder ko chipkane se pehle check karna sabse zaroori hai, kyunki ek baar lamination hata di ya glue lagaya, toh warranty khatam.
- Connect Outside: Folder ko bina frame mein bithaye, bahar se connect karein.
- Touch Test: Ek App icon ko pakad kar poori screen par ghumayein. Agar wo chhooot (drop) nahi raha, toh touch OK hai.
- Keyboard Test: Message box mein jakar saare keys type karein.
- Bright/Dark Test: Brightness full aur zero karke dekhein (kabhi-kabhi low light mein screen jhilmilati hai).
Step 2: Purana Folder Removal & Safety
- Heating: Separator Machine (90°C – 100°C) par phone ko 2-3 minute rakhein.
- Cutting: Plastic Card (X-Ray paper) se kaanch kaate. Metal opener use karte waqt dhyan rakhein ki Battery puncture na ho.
- Pro Tip: Agar kaanch bahut zyada toota hai, toh uspar pehle Cello Tape chipka dein taki tukde udein nahi.
Step 3: Frame Cleaning (The Most Important Step)
Fitting kharab hone ka sabse bada kaaran: Ganda Frame.
- Corner Cleaning: Frame ke charon konon (corners) ko chimti (tweezer) se khurach kar saaf karein. Wahan kaanch ke barik tukde chipke rehte hain jo naye folder ko tod dete hain.
- Chemical: Thoda sa Falcon 530 ya IPA kapde par lagakar frame ke kinare saaf karein taki purani gond hat jaye.
- Bend Check: Frame ko aankh ke level par rakh kar dekhein ki wo tedha (bend) toh nahi hai. Agar hai, toh seedha karein.
Step 4: Transferring Small Parts (Jo Sab Bhool Jaate Hain)
Naya folder lagane se pehle purane folder se ye 2 cheezein nikalna na bhoolein:
- Speaker Mesh (Jali): Upar earpiece ki jali. Agar ye nahi lagayi, toh phone ke andar dhool jayegi aur camera kharab ho jayega.
- Sensor Rubber: Proximity sensor ka kala rubber (Lesson 27 wala). Agar ye nahi lagaya, toh call par screen band hone ki dikkat aayegi.
Step 5: Professional Pasting (T-7000 Trick)
Ab baari hai Mobile Phone Combo/Folder Replace ke final step ki.
- Glue: Hamesha T-7000 (Black) use karein. Yeh light leakage ko rokti hai. (White folder ke liye Transparent B-7000 use karein).
- Application: Frame ke kinaro par patli layer lagayein.
- Warning: Sensor, Camera, aur Speaker ki jagah par glue galti se bhi na lagayein.
- Wait: Glue lagane ke baad 1 se 2 minute rukein. Jab glue halki sookhne lagti hai tab pakad mazboot hoti hai.
Step 6: Pressing (Rubber Band Logic)
- Folder ko connector se lagayein aur frame mein bithayein.
- Rubber Bands: 4 se 6 rubber band lagayein.
- Caution: Rubber band ko Camera aur IC area par zyada tight na karein. Zyada pressure se naye display mein pink line aa sakti hai.
- Time: 3-4 ghante sookhne dein. Fir extra glue ko haath se ragad kar saaf kar dein.
Summary Checklist – Mobile screen replacement
- Warranty Check: Chipkane se pehle test karein.
- Corner Cleaning: Kaanch ke tukde nikalein.
- Transfer: Speaker Jali aur Sensor Rubber transfer karein.
- Wait Rule: Glue lagakar 1 min rukein fir chipkayein.
💡 Aaj Ka Aapka Task – Lesson 28 (Comments & Forum)
- Practical: Koi purana dead phone lein aur uska folder nikal kar wapas lagane ki practice karein. Dhyan dein ki nikalte waqt LCD na toote.
- Comment (नीचे): Kya aapne kabhi Speaker Mesh (Jali) lagana bhoola hai? Uske baad kya hua?
- Forum: Agar naya folder lagane ke baad “Touch apne aap chal raha hai” (Ghost Touch), toh iska solution Forum (forum.teamtw.in) par discussion mein dekhein.
