Samsung Ch@t 322 Power Problem Solution
Good afternoon, this time I decided to write a small review of the causes “non-inclusion” of mobile phone Samsung Ch@t 322 . Several days in a row, get me these phones after water malfunction “not included” and part of this defect similar reasons.
The most important factor in this state phone is water. If, after falling into the water your phone continues to run for some time, in any case, do not leave the battery in it, and so do not try to over-charge it, do it, you should not!
We return the same to repair phones that have come to me in different states, describe their conduct repairs:
Samsung Ch@t 322 does not turn triggered vibration
At first glance, this is one of the most common problems of this brand. The essence of the fault which is damaged contacts between the processor and memory chip NAND. That the majority of “cured” of moving the welds or “sandwich” CPU + memory.
But it was not my case. thanks voltage table, which I did for convenience and faster fault isolation and checked all voltages.
Be overestimated voltage VIO , instead of 1.8 volts there were 3 volts, is responsible for its formation power controller GAZOO 3.4G . After sequential testing majority of chips are on this bus, found the culprit power surges. The problem was extensive oxidation under flash chip N1410 , took it off and excess voltage VIO disappeared.
Samsung Ch@t 322c will not turn on no VR1
Checking all the voltages on the table, there was no voltage VR1 2.5 volts. It turned out that when the phone is no run of the radio and therefore the absence of lasing output N7500 . The problem is in the controller supply GAZOO 3.4G after his replacement, tension appeared and phone safely started.
