What else I should do I have tried the hard reset even recovery but no successful. When turn off and turn on again apple logo show up for about one- two seconds than black.
Did you disconnect the battery before removing and installing the LCD (see step 42 of this guide)? Not disconnecting the battery can cause backlight circuit damage. This would require a micro-soldering repair. It is also possible that the LCD is defective. Depending on how damaged your original LCD was, you could always try to put it back to see if it “works” like it did before the repair.
