Check out this talk by Chris Gerlinsky at 33c3 (2016)[1] about how he went about cracking the encryption of cable/satellite television set-top boxes. It is a very detailed talk, and he goes into detail about delaminating a ROM chip and visually extracting the contents of its memory bit-by-bit using a microscope and then software to speed things up a little. It's a long talk so he goes into more detail about the rest of the process, but I really enjoyed it.
