Naya Ya Second-Hand Mobile Letay Waqt Dead Pixels Kaisay Check Karein 🔍

Dead pixel screen ka woh chhota sa dot hota hai jo hamesha kala ya kisi aik rang mein atka rehta hai. Dukandar aksar kehta hai "screen bilkul ok hai", lekin ghar aa kar pata chalta hai ke aik kala nuqta mojood hai. Is se bachne ka tarika bohot aasan hai. **Test ka tarika:** Phone par koi **dead pixel test website ya app** kholein (jaise "dead pixel test" search kar ke). Yeh screen ko poori tarah laal, neele, hare, safed aur kale rang mein bhar deti hai. Har rang par screen ko ghor se dekhein — agar koi dot rang nahi badal raha ya kala nazar aa raha hai, to woh dead ya stuck pixel hai. **Stuck pixel** (jo aik rang mein atka ho) kabhi kabhi theek ho jata hai — us jagah halki malish ya pixel-fixer video se. Lekin **dead pixel** (jo hamesha kala ho) hardware fault hai aur theek nahi hota. ⚠️ Warning: 1-2 dead pixels par warranty claim mushkil hota hai — zyada tar companies isay "acceptable" kehti hain. Is liye khareedne se PEHLE check karna zaroori hai. Second-hand phone lete waqt to yeh test lazmi karein. --- 📍 Mian Traderz, Sahiwal — Mobile Repairing Center 📱 WhatsApp: 0347 8750000 🔧 #MobileRepairing #MianTraderz
