Default Re: Hameg HM208 Oscilloscope Timebase fault

Hi Symon,

In your first post you indicated that the fault seemed to be heat related.
Without getting into the operation of the various circuits, and even if it is now a permanent fault, you might try using freeze spray to identify the faulty component.

You could also verify if the horizontal amplifier works in the X-Y-mode. That would eliminate partly the possible source of error and might get you closer to the faulty section.

Regards, Peter
