C75频繁自动关机？

qyguang

我年前在网上买了一个C75，水货，刚寄过来时看着还好，用着也没问题，但是用了十几天之后就频繁的自动关机，屏幕渐渐得暗下去，然后就关掉了，后来开了不到2分钟就自动关掉了。但是不放SIM卡得时候就没有问题，不会自动关机，也能打紧急电话，那么放着呆多长时间都不会自动关机。都说是软件问题，一个朋友帮我刷了一下，网上只有22版得fm，map和ffs没有22版的，刷过之后还是不行。去修手机那里都说是软件问题，但是还都刷不了西机。不知道有没有人遇到过这种情况，帮忙分析一下吧，谢谢了。

我曾经有个CX70也是这个毛病，在俄网找到一份文档，解决了，如下：

Subject: “Switch Off” with C65,C70,CX70 Infineon Chipsets

Dear all,
in a some cases the above mentioned mobile phones manufactured before date code T7 and
assembled with Infineon Chipsets
show automatic “Switch Off” problems.

Attention: The majority of C65, C70, CX70 are not affected, due to usage of “Hitachi Chipsets”.

Explanation: There are 2 failure causes.
- A software caused problem ( Exit Code 004)

- A hardware cause problem ( Exit Code 008)

( timing of the 26MHz oscillator)


Solution:

Check the exit code (use X-Focus)

- For the SW-Problem, a software update > SW 54 solves the problem
- For the 26 MHz oscillator timing, resistor R4019 has to be replaced versus a new one.

Part-Number: L50652-C391-J2
Value 390 Ohm

Reporting:

The SWAP boards on stock have to be repaired as a bulk repair (separate reporting)
Due to the fact that you are doing a bulk repair find ing we are ready to pay to you 70 % of the agreed level 1 repair fee.
Please do not report these bulk repairs within your “normal reporting” .The costs for this bulk repair of the local swap boards please state under “Extra Repair” within your IRIS documentation. On a separate excel spreadsheet please indicate number of repairs and IMEI-Number.

The repair of a field return (with Infineon chipset and respective exit code) is a “level 1 repair” due to the not required fault find ing and detection time.
