- When i turn it on most of the times show full screen noise and hangs, sometimes just hungs.
Not sure if its the same reason, but I had a period of same symptoms.
Additionally (after switching channels off and on again to get rid of noise) it often failed to see any signal in 1kHz testpoint. Even auto button failed in such situation. Crashed 90% of times when auto button was pressed. Ch2 off cleared ch1 trace also. Which returned many seconds later with noise again. Rarely also with clear trace...
Updates didnt change a thing. Clearing fram neither.
Until I noticed that it also forgot my measurements and switched on both channels on every reboot, although I clearly switched off ch2 every time...
That last one finally made me read some manual and what do you know - its a setting: Utility > System > Power on
I had set it at some point to "default". Perceiving it for some reason (without reading manual, just wandering around at menus) as that computer bios feature that restores power to the "last" state in case of power loss. So in that context, "last" sounded wrong.
Anyhow, now at "last", havent seen abnormal weird noise-like stuff on screen upon startup nor hangs for some time. Before it was always at most couple of restarts away.
PS. spoke too soon. Distorted noise-like stuff is back, hangs too. Seems to just occur less often, but it isnt gone.
