I also have a similar setup with 2 Pro Medial 2.1 speaker systems. Loved them when they worked.
Now I lost subwoofer on 1 system and channel amp on another.
I have electronics repair background and could do component level repair. However these days it is cheaper and faster to just replace the board. Besides, I no longer have access to an O-scope. Was hoping to find replacement, updated, circuit boards for replacement. Possible? Anyone ever do this?
Found some web pages that go over repairing the board where the power resistors have deteriorated the solder joints. I will start there with upgraded power resistors. Will try to update this thread with my accomplishments.
