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
