Nokia 1616 LCD Light jumper
Nokia 1616 is very popular handset is our BD country. It may be many kinds of hardware problem, but LCD Light is one of the common problem. This phone’s LCD and keypad light part has make using a transistor and a diode. Maximum time damage transistor for this problem, but transistor is not available. So this problem repair is hard/ but I make a solution of this problem without transistor. Now I showing how to repair this problem without transistor, Only using jumper.
See the image bellow :
How to done this work : first check VCC voltage of light coil, then check LCD Light. If you see coil voltage ok but LCD light not found, then check transistor and diode, if they are damage then make RED and yellow mark jumper. After that cut RED mark print near by keypad LCD light. Make same jumper of this image of this image very carefully. I am sure it work 100%.
