Hi @mishra14557
The touch screen in the phone is not a separate component. It is integrated with the LCD screen i.e. one complete assembly.
If the touchscreen is faulty then the display assembly needs to be replaced.
Here's a [https://www.youtube.com/watch?v=OLKX4-Dt4mw|video] that shows how to replace the display assembly.
Search online for [https://www.google.com/search?client=firefox-b-d&q=honor+10+display+assembly|honor 10 display assembly] to find suppliers that suit you best.
