First, regarding the home button: on the logic board (right beneath where the Home Button sits), you can see 2 pins. The home button is no more that a "switch" that connects those two pins when you press it. You can obtain the same result by shorting the two pins (careful, you can pry them of the board or break them), or by shorting the left pin to the metal frame.

1/ Display cable is not damaged at the tip;
2/ Display connector on the board does not have missing/broken pins;
3/ That the retaining flap is not broken or missing, and that when you insert the cable in the connector, you are flipping it correctly to lock the cable in place;
B- Then hard-reboot your iPad by pressing & holding Home Button + Power Button together for ~12 seconds. If the iPad doesn't restart then, click the Power Button once to make it start. This should fix it unless:
B-1/ you have a "backlight problem" meaning that you've blown a "fuse" or burnt a filter during assembly; in which case your iPad's logic board will need repair by a specialized repair-technician able to do micro-soldering;
-
B-2/ You pulled on the display cable during your first repair attempt, and damaged it somehow. In which case you will need a new display. A good way to tell is to hook another "known to work" display and see if it displays an image.
