6th Gen Ipad Screen not working

I have a 6th gen iPad. It was working fine, has always been in a case, never dropped or anything spilled on it. I factory reset it since I was preparing to trade it in, then Covid struck so I had to delay. I went to use it while I waited for restrictions to be lifted and the screen won’t work. I’ve done all the resets online and tried plugging it into my computer to push a back up through and that didn’t work. It will give me audible commands so I know it’s on and working, just no screen.
