Hello Ozzyboy and welcome. Lots of great information available on this forum.
Of the doors that have had the screws pulled out I have not heard of door replacement.
Those that had screws pull loose have used either an aluminium plate or piece of plywood. A piece larger than the bracket that pulled loose was glued and screwed to the door, then the bracket screwed to that plate.
Perhaps someone that did that repair will chime in here with pics.
Peace
Dave
