Hi @gujjalswaroop
No. The touch screen is part of the display assembly. It is one complete module i.e. LCD screen + digitizer.
If the touch screen is faulty you will have to replace the entire display assembly (unless it is a systemboard problem that is)
Here's the ifixit [guide|147787] guide, that shows what to do.
Search online for ''5600020K1900'' to find display assembly suppliers that suit you best.
