My 2467B has developed several problems with the display; I'm not sure if they're related or not but they started about the same time.
The first is if I put a sine wave on the screen and center it, it shows considerable distortion. If I move it well above or just below the center line it displays clean.
Secondly, as soon as a signal is applied the upper and lower readout will oscillate like a sine wave is passing through them. Still readable but definitely not proper.
It's my favorite scope; I'd be grateful for any suggestions on where to start looking.
