Member: 154612 Status: Offline Thanks Meter: 824 | W200 display light: 1.First make sure that problem is not on lcd side. When phone get`s some water lcd Led anode and cathode are shorted. U can check that by measuring resistans between lcd 2nd and 3rd pin. 2.Measure voltage on C870, there must be ~5,5V if phone is powered on and not in idle. 3.If 5,5V is not present Check that Vbat reach to C869, if not most probably R831 is damaged, must be 5R6 Ohm`s. 4.If still no luck, try changing Led Driver (TPS60231) D802 5.If still nothing Replace processor (DB2012) D300 Best Regard`s Janar |
