You are on the right track, but remember the logic board has to relay the touch info to the processor and the screen is plugged into the logic board. If the board took a big impact and any traces were broken during the impact, then you may be out of luck. I don’t micro solder so I don’t know if there are any fuses etc that can go out or need to be replaced, but your issue is more than likely a board-level issue. Id find someone reputable to send it to.
