Rep Power: 8  | Re: k310 lapu keypad mati Walah belum beres toh ....  Dioda Led & Resistornya sudah di periksa, masih baik gak? Jalur Connector keypad ke Dioda Led&Resistornya uda diperiksa masih baik gak....PIN5(+) & PIN10(-)? Qlo hal2x tsb diatas kondisinya masih baik, Kemungkinan ada yg sakit pada komponen2x seperti terlihat pada gambar. (V907=Transistor NPN, R900=resistor basisnya, dst ..... CHECK & REPLACE IF DAMAGE !!!) Utk periksa dgn cepat, Jumper kaki2x CM900 lalu hubungkan ke Ground, seharusnya led keypad langsung nyala (qlo hasil jumper gak dilepas, maka lednya bakalan Nyala terus  ), Qlo hasil jumper lednya gak nyala maka jalur positif PWB-nya ada yg putus.Periksa dulu yach ....
