I followed the instructions found here to program a new video ROM: https://tinkerdifferent.com/threads/this-is-what-a-bad-macintosh-se-30-video-rom-looks-like.1446/
To create a new video ROM, I used a GQ-4x4 to program the AT28C64. Then I compared the original video ROM file with the one on the new AT28C64 with HxD. Both were identical. However, the new video ROM gives me this screen on the SE/30? Any hints what could be wrong?
