So pretty much when one is having an issue, say will not detect, output data, or detects wrong. I am under the impression that there really is no hope of correcting the issue and recovering the data, would anyone else agree disagree?

If you open the package and look at the components, pcb etc, do you see any possibility of repair/replacement/swap? Probably not.

I have and not at all, like I said, what I figured, but people on here are brilliant, I wasn't asking for how it is done, just wanted to know if there had been any success
