Hi
I'm toying around with this TSOP48-chip salvaged from my daughter's dead Android-tablet, just for the sake of practising. I've been following all documentation I can find, all videos I can find, and I think I've got a grasp of what to look for when describing the internal structure.
However, this particular chip seems like a dead-end for me, and I'm thinking it might be broken.
See image 1:

There's a lot of patterns and the variations look good. I'm scrolling rightwards to find the vertical lines, presumably the SA. I find it at offset 1024:

However, the lines are plain straight, no variation at all. According to the docs, atleast LNB should be variant since it's not the same for all pages. So, something is fishy here.
Also, from offset 1161 and all the way to the end (4319) there's no data at all; plain gray:

I've retried dumping the chip in full two times, but the gray area appears everytime.
So, questions:
1. Am I searching for the SA at the wrong place?
2. Is the chip partially dead?
