The Toshiba Excite 7c is a tablet released by Toshiba in 2013. It is a 7 inch black tablet with a white or gold back, front facing camera, SD card and micro USB slots.
I have found it is possible to find another device with something else broken , like the case or the motherboard , and use the screen from that. There is a guide here.
The Toshiba Excite 7c does not have a replacement screen. This is because the screen of the way that this device was manufactured . you will need to buy a new device in order to replace the screen.
