Hey there! Based on your question, it sounds like the touchscreen on your Hisense E70 TV may need replacing. Some options from the PriceCheck search results that could help are: The Digitech JL-1720 Hisense TV Remote Control for R167 and Replacement TV Remote Control For Hisense EN3C39 Hisense ULED TV for R400. A new remote control is a good first step to try if the touchscreen isn't responding but the TV itself is still working otherwise. If a new remote doesn't do the trick, your best bet would be a replacement touchscreen like the Sintron OEM LCD Screen Replacement for Hisense TVs, available from R649. Installing a new screen will likely fix unresponsive touches. Hope this helps point you in the right direction for resolving your Hisense touchscreen issues! Let me know if you have any other questions.
