Cost of repairing or replacing micromax funbook P300 touch panel

I just had fixed my tablet white screen issue but now another problem, I dropped tablet from bed and now tablet has an scar.. yes its like a scar, a thin line is going through middle of the screen, table it is all working fine and everything is working as new but only a thin line like you see on broken glass is there and I think I can't get it repaired in warranty, so how much it will take to get replaced touch panel ? I think LCD screen is intact and only touchpanel as this line. Or they have some kind of protector which is broken because everything is working fine only apart of this visible breakage line..

I think you should visit service center nearby and ask them for quote.
