Hi,
I have a new Pro 163 and it has an awful hum. The frequency of the hum changes with the intensity of the backlight (hitting DIM changes the frequency of the hum). It is impossible to use headphones as the hum is too annoying. It doesn't seem to be a grounding problem or interference from a computer.
I have a 164 (portable) with absolutely no hum at all.
Should I bring this 163 back to RS?
