I am having a strange problem with a 28KSR. The characters that are physically in the top row of the typebox only print the bottom half of the character. That is, the H, M, N, O, T, 5, 9 and # are not all there. A picture is worth 1K words: https://photos.app.goo.gl/3ttqAgXf5nkvFqeb8

I substitute a typebox from another 28 and the problem follows the machine, not the typebox itself.

Anyone have any ideas or suggestions?

Thanks in advance!
