    Jalur On/Off Cross CB91 emang sangat mudah putus dan putusnya bukan diantara pad on/off ke titik point di bagian belakang PCB ataupun ke Resistor.
    yang sering kejadian adalah putus antara resistor ke IC MTK 6253. dan setelah meneliti jalur On/Off tersebut antara Resistor 1K sampai ke Kaki MTK gk ada titik point yg bisa dimanfaatkan. jadi jalan satu2nya adalah dengan mengangkat IC MTK dan melakukan Jumper dikaki IC tersebut.
    untuk detail jalurnya mohon maaf sy belum bisa upload sekarang coz masih nunggu sesuatu:D.
    Mohon sabar untuk menunggu trik jumper jalur on/off MTK 6253 akan sy upload dalam 1 atau 2 hari ini.
