Hi, I just recapped a Mac Portable M5120 logic board. It has no sound to the internal speaker, the external jack works however. I found C9 (+) was not connect to pin 11 of the Sound Left Chip. C10 (+) was connected OK to Sound Right. I also found that the speaker (+) does connect to 2 leads on the external jack (see attached). Speaker is tested OK in my backlit portable. Any thoughts? | Posted by: Brooklyn on 2023-12-18 16:06:59
I have already solved this- the via connecting (-) C9 and R91 on the back side of the board was broken. Bodged this connection and all good! | | 1 |
