Lawrence Kumar, If the tablet has been dropped 2x and display is not showing, the Screen/LCD may be damaged. Use the 1st link below to disassemble the device to check internal plugs/wires/components for loose/damage and if need be change the display assy. 2nd link is display assy., Lifetime Warranty available through iFixit store or do a search yourself for possibly lower pricing. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
