nothing appear on screen , tried to replace the screen and still same
Hello
i got a galaxy s4 which is not turning on
i plugged the power supply to check if the motherboard is working , and i got a sign of Amperes meter of 0.25 and varying, which mean the motherboard is ok but the screen was not showing anything
then i tried to see if the problem were the cables , but they were fine , none of the copper terminals of the cable was damaged
after that i tried to replace the screen , but still the same problem , its not showing anything
is my method of checking is right ?
and what could be the problem now , did i miss somtihng ?
please help me to fix it
thanks
Is this a good question?
