Hi guys,
I recently purchased a Tek 465B on eBay and have a weird display issue.
There is a strange dead spot on my display always in the same position. It is a round circle where the trace is blanked out. At first I thought something had happened to the phosphor coating at that location and it was burned out.

Has anyone seen something odd like this before?
