Nokia 1616 set.It popular hand can be of many types of hardware problems, but the problem of the liquid crystal light is a common problem.This phone lcd light and part of the keyboard to use a transistor and a transistor damage diode.Maximum time for this problem, but the transistor is not available.So repair this problem is hard.But make a solution of this problem without transistor.Now show how to solve this problem without transistor, using only the pilot. 
Hoe to make this work : First, check the voltage Vdc coil light, then check lcd light.If see coil voltage is wrong , but the light is not lcd then check transistor and diod if tey are damage to red and then yellow red mark jumper.After spooler mark near the keyboard LED light. Make this photo the same rider carefully.
