Hi there i am trying so hard to learn.
I have nokia lumia 625 no power in my lab.

Iam checking for broken tracks with multimeter on diode way .with the ground and test point while on charged to check the lines.

In one line i dont get value at all.Its a test point that is printed on pcb.

Other thing...I soldered wires to battery conection but the power suply cut voltage.- and + So it seems impossible to power with the power suply.

i have give voltage with USB charger.Iam getting about 2.00 volts on battery terminals and about 1.80 on power button.

While on voltage and when check with diode way measurement.some CAPACITORS near Power ic gives BEEP on multimeter on both sides.Three of them wich seems to be on the same line.

I have the scematics for any help.One great member share it here!!

Facts:No usb sound when conect to PC.Power ic and Cpu are installed with glue.

History.The phone was droped down and never powered on again.!!!!

Lets brainstorm
