@@trcteck ek board hai mere pass 280 G2 ka usse maine bhi testing Kara aur fir maine ek chip level wale technician ko dikhaya tha problem usme hai ki uska processor heating nai kar raha power on hota hai beep bhi nai deta, processor ke side Mai lagge non polarized capacitors beep karte hai dono sides se multi meter mai jab processor laggake check karta hun but jab processor nikal deta hun tab sirf ek side beep karte hai it's means VRM IC kharab hogi kyuki wo bhi badal ke dekhi thi oss technician ne
