INTRODUCTION
You don't remember me, but I remember you... (nah, it's not the Grease song!)
Okay, not really. Enough digressions! Some of you may remember me from the LCS-8038TX thread. As you might have noticed from my previous thread and this one too, I mostly mess with sub-$100 equipment. Most would say worthless stuff, or at least not worth the time or bothering. Well, the primary reason I'm trying to fix them is to (hopefully) gain some experience whilst not breaking something wildly expensive, but also because it's fun (for me) to see something working neatly again. So, if you don't feel like wasting time on such a thread, for your own sake, stop reading now!
THE ACTUAL ISSUE
Wow, you've decided to read on? Thanks!
On to the issue. As the title says, this subwoofer I'm dealing with is having a problem with being partly mute. Of five terminals where you can connect a speaker, only one output works (plus the core subwoofer speaker). Perhaps I'm doing something wrong, but I get sound output only when plugging an external speaker in the rightmost terminal (take a look at the first picture in the attachments), regardless of being in the AC-3 or 2-ch mode.
I took a photo of the main PCBs in case there's something I've overseen, as well as the service manual (downloaded from here), to clarify at least some of the doubts you might have while reading this post.
Once again, thanks for your time and any provided feedback!
