Did you turn off the iPad when unplugging the LCD and replugging it?

I'm not 100% sure if unplugging the battery is required as well.

No I didn't completely turn it off but I did a hard reset and that still did not solve the problem

So right now it is showing no display but a dim backlight around the screen or something along the lines of that? Could be backlight fuse(s) blown or if unlucky LCD ribbon cable gone bad.
