Hi there today i repaired a samsung mobile .
The problem was it cannot be powered "ON" no matter what i do. So i tried to charge it and I'ved noticed that it the charged icon displayed.
I conclude that these was hardware related. So i opened the device and test the tack button which serves as power on. And use dmm tester to see if it functions well...BOOM gotcha" haha the tact doesnt responde at all. So i used my hot air to remove the defective tack.
I replaced it with new tack the same size and pins.I test it again and Boom let there be light haha... the circuit now reponses well. I inserted the battery and powered it on. The boot sequence now appeared and it functions well.
I returned now the cover and the srews and inserted the sim and sd card ....Ooops we forget something the battery haha.
I powered on now the phone and burned test it.
whoah it was good now.
Thank you for reading.
