The LG G Pad Tablet 7.0 was released in 2014, it is an Android based produced by LG. This device is the first produced tablet with a 7 inch screen and a 1.2 GHz Quad-core processor. Model number LG-V400.
you might have damaged the display, I just replaced mine and it was super easy. the hardest part i would say is to find a way to heat up the screen a touch to get the glue to let go. keep in mind you have to disconnect the battery before your done to get it to accept the new screen.
update: you can see that the screen turns on but it is still totally black
