Lenovo Yoga 720-121KB Type 81B5 Touch Screen No Longer Working

My touch screen has been working fine however the touch screen is no longer working in either the laptop mode or the tablet mode, which of course makes the tablet completely unusable.  I do have the auto install set for upgrades.  I have searched the Forum and the Google web for possible solutions but nothing seems to work.  I have run the "Lenovo Check System for updates" but get a message that the lastest drivers are installed. 

 

Here are my System specs -

   System SKU:  LENOVO_MT_81B5_BU_idea_FM_YOGA 720-121KB

   BOIS Version/Date:  LENOVO 5GCN29WW, 11/1/2018

   SMBIOS Version:  3.0

   Embedded Controller Version:  1.24

   BIOS Mode: UEFI

   OS Name: Microsoft Wiindows 10 Home

   Version: 10.0.17134 Build 17134

 

Need advise to get this working again.

Hi PapadReed! Welcome to our forums community. Was there any recent changes or any updates installed before the issue arise? Try running a hardware scan using the Lenovo Vantage app to check for hardware failures. We can see on our website that there is a firmware update. Just to make sure that you will be installing all the updates, run the update through the Lenovo Vantage and install all available updates. Check if the issue still persist

I used the Lenovo Vantage app and installed the one update that was found.  Rebooted laptop but this did not fix the touch screen problem.
