PC Engine GT recap Sound issue

[choijimmy]

Hi All,

 I just did a recap for another GT. The sounds works for few hours ( both headphone + speaker ).
Strange enough, after few hours, the speaker No longer has sound anymore ( the headphone still good ). For now, I tap the wire from the speaker jack to the speaker directly and works fine. However, the issue is the speaker will still On even you inserted the headphone. 

This is 2nd time I ever see this issue... Any idea? I suspect the headphone jack issue ( eg, it always think there is headphone has been inserted, so disable the speaker... However, I am not so sure )

Yes, phone jack issue. Replace another one and works fine

Yeah, the phone jack has a pin that's connects to speaker circuit when the earphone is not plugged in.  Sometime this pin breaks.
