My favourite scope, a TDS 694C, has developed a nasty screeching sound when
the display comes on. It's quiet during boot-up, but when the screen comes on
the sound is very loud and unpleasant. Any wisdom?
The downside is that you may feel compelled to kick yourself for not ditching the CRT earlier. Also, no more trippy head spinning when your gaze accidentally sweeps past the color shutter!
