Hantek DSO1062B screen flickering

[strtfr]

Hi,

A few days ago I received a Hantek DSO1062B handheld device. Immediately after power up I noticed display flickering on the horizontal display lines. It is worse during bootup and momentarily halts when the display shortly locks. I have used auto calibration, changed display colours, changed display refresh rate, disconnect charger, let it warm up, check for software updates, but nothing solves the problem.

In the worst case I have to send it back. But to be honest this is something I would like to avoid. Although the seller has yet to respond, I would like to inform if someone already has some experience with this issue. It seems that the screen is picking up some interference, probably from the scope itself. Besides this screen problem, that is really a bad thing.  Any pointers?

It's actually a decision between opening up or sending it back, so ..

Thanks
