Touchscreen not working: LibreELEC / Kodi 17.3 / Estouchy Skin

  • Hi
    >> see my signature file for system configuration <<

    I repurposed my 30+ year old home intercom to have a RPi + Touchscreen [see photo]

    All I want to do is listen to streaming radio, pandora radio and play MP3 from my home NAS unit.

    History:

    I had a working OpenELEC install from May 2016 then a month ago the touchscreen stopped responding at the perimeter.

    My techy son suggested to upgrade the software - which I've done.

    Now with LibreELEC 8.0.2 / Kodi 17.3 / Estouchy Skin I can't get the Touchscreen to work on many icons.
    I've made a .MOV video if that helps you.

    When the mouse and keyboard ARE connected the RPi + Touchscreen functions great.

    I DO have the Enable Mouse & Touchscreen support ON. [On Settings > System > Input > ]
    FYI: The touchscreen only minimally works on the Estuary and Confluence skin too.
    With NOOBS installer I only installed LibreELEC, not Raspian ... if that means anything.

    5v 2A Power is connected to RPi and jumpered to the touchscreen [made the lightning bolt go away]

    I really need your help. Thanks ... Jim

    EDIT 20170728:

    Is it possible that LibreELEC 8.0.2 does not have the correct DRIVER for the v1.1 [2015] Official Touchscreen??
