Yes its possible.

open your phone app and dial *#*#3424#*#*

this will open the HTC Function test program.

Hit ''ACCEPT''

Select ''Line Drawing Test''

Hit ''Run''

Then try to draw a line where you think your screen is defective. If you can't draw lines then your phone must be sent for repair.
If I've helped you, please hit the ''tanks'' button
