e715 no speaker no ring and vibrate

[redouan]

Last month, I saw a lot of E715 with the following problems: No ring, no vibrate and voice. I checked it carefully , the speaker and line are good. I think these above problems belong to the main board . I tried to repair it many times . But it still the same . Who have repaired it? Please share the solution with me .
Thanks in advance.

Are you sure that the flex cable is ok(the problem might be this link (http://img63.imageshack.us/img63/9924/e700ribbon14kx.jpg)) ? If it is, check cn200, u201,u202,u300 and u303.
