50% of the screen is white

Just finished building my build on a new 10"model, and the screen looks like its not working. Half of the screen appears to be white. Tried the tips I’ve seen on the forums but no help (the hdmi flag etc).
Where the ribbon goes into the board isn’t flush, and I’ve tried pushing the top to make it go it, but it doesn’t fully. It looks like the clip is not sitting flush.

the screen powers up like so
