Hi.

I have been experiencing a problem with my Hameg HM208 oscilloscope. It was working correctly then the trace suddenly went back to the left of the screen. It seems the timebase stopped. The Y amplifiers are functioning as there's vertical deflection of the dot when then probe centre is touched.
After a while of the scope being off, I once again tried it and found things were back to normal, but after about 7 minutes the timebase appeared to stop once again. This happened on a few occasions but now it's permanently faulty. It would seem the fault was initially temperature sensitive.

I was wondering if any other members have experienced timebase problems with their Hameg scopes and recommend a course of action. I do have the original hard copy manual hiding somewhere in the loft but have also just downloaded a copy from the Rohde & Schwarz website.

Regards
Symon.
