I wonder if it was a bad section inside a chip that they compensated for ? maybe a bad PCB trace?
hard to say. But it is interesting nevertheless. Looks like a whole new IC put into place?
Now-a-days, they would just toss the entire board into the scrap bin and put in another. But thats if they run into the issue to begin with. Some factories only test 1 out of every group of 20 or more, especially with LCD TVs.
