Lightning replacement - one speaker is mute

Wow... How much ignorant I am in schematics despite I do many repairs for myself! :\ (shame on me)

Many thanks, that's exactly what I needed :)

Live and learn...every day! :>).

Sorry, one more question! In regards of orientation - do I get right that the first pin is on the side closer to the edge of device and the 32nd is closer to the battery? It's logical to decide so because it's shown in the same orientation as on the MB main drawing but I want to be sure

I believe 1 is closest to the battery and 32 is closest to the case edge. Normally, the pinout follows the orientation of the way the connector is placed on the schematic.

In this case, PIN 1 is the top-left pad, viewed from the same orientation as my image. The left hand column is odd number and the right hand column is even numbered.

Like this:

1

---2

3

---4

5

---6

etc.

Logic doesn't always apply to connector or IC orientation because sometimes a different orientation will make the traces easier to route. When in doubt, look and probe for GND pins and determine orientation that way. Or if you have access to a tool like ZXW, it will show you where Pin 1 is.
