How do you can repair your china(chip) dead phone with a power supply(DC Supply).
I share here my some idea . (1) 1st check dead board via volt miter have short or not? if not shot you can go ahead for next step. (2) take power supply war and connect phone v+ with power supply v+ and v- with phone v-. (3) press phone power button and see phone volt reading........its show what ?  (4) if power supply reading nothing i mein reading0.00 change cristal clock ....then check volt . all is ok set must go on ,cause main ic not found power 4 this missing. (5) if power supply do reading 4-6 its 1st try to format or flash ....if set not open ..then re-hit power ic with hot air and solder pest.all is ok set must go on. (6) if power supply reading 35-45 reading ....its must be flash ic(Ram) problem ....now re solder flash ic with hot air . i hope its useful for all. if my post like inspire here. |
