Why does my tablet respond to S-Pen but not my fingers?
I just finished repairing one problem I had, where the screen gets all discolored. Once I closed it up and started it, it would not respond to my touch, nothing. I tried the S-Pen and it worked fine. Does anyone know what could have caused this? I reopened it and check the ribbon connections, the only one that looks questionable was the central ribbon cable. Now, I don't know much about electronics, but I noticed that on all the other connectors for the ribbon cables, there was a locking switch. I don't think the connection this ribbon cable has one, and I fear that out of ignorance I may have damaged the connector attempting to flip the non-existent locking mechanism. I believe this to be the cable that connects to the front screen (Not the LCD), and is what is used to communicate the touch input. So I think this is where my problem lies. Can someone enlighten me with their perspective on this issue? I think it must be a damaged connector (requiring me to get a replacement motherboard), the ribbon cable isn't fully connected (tried my best), or something else I am not seeing. Hopefully it is fixable, I would hate to have to scrap a tablet just after 5 months of use. Could it possibly be a broken or damaged digitizer? I have dropped it a few times.
Is this a good question?
