My micromax q372 fell down and got cracked at the top right, I recently replaced both the touch pad and the lcd, but still the screen doesn’t work when I turn it on, it vibrates, registers the touch, but nothing shows up on the display, what could be the problem???

Firstly, the Micromax Q372 has been a problematic phone right from the start, there have been many complaints about its cameras back and front, its charging socket. To me, as I’ve done many replacements of touch and lcd’s you must have done something wrong and/or shorted something out, while replacing the touch/lcd, undo your work and try to reinstall the touch/lcd again and see if you missed any connections
