Guys I'm having a similar issue, Amazon digitizer. Worked great till I put SD card back in and it restarted then had the issue described above. Took it back apart and plugged old one in (ghost inputs) and got nothing from it. Restarted with old one still plugged in and it worked again, plugged new one in and again it worked flawlessly until I reassembled and turned it back on. Did this a few times and now I have reassembled everything with touch screen input test up, still working great but haven't put the SD card back in or reset the device since getting the new digitizer to work again. Could this be the same v1, V2 issue described above? Seems to me like a software thing idk. This is my first switch and I'm giving it to my son for his birthday in a few days. Just weird how it will literally go from working fine to nothing with just a power cycle. Not sure which version I have but controllers are blue and orange. I haven't tried an actual game chip? Yet as I don't own any but the digital loads fine, can scroll through everything as it should. I don't want to keep taking it apart just to get the new digitizer to temporarily work or not be able to have storage expansion just to have touch screen. There's got to be an answer. I've seen the comments about 3rd party things that can calibrate the screen and seems like maybe thats what I need but I have no idea because again, I've never had or dealt with a switch before let alone trying to jailbreak one and install 3rd party stuff just to make this work. Any ideas?
