You need to check if voltage point is normal. File size is limited. Please contect me by email, my address is wangshuang@hantek.com

Thanks for your help, wangshuang!

In my case 1.8v DC DC converter IC was broken. Since it is 600 mA current only, it can be replaced by simple linear LDO DC DC like 1117-1.8 easily, there is pretty much free space around to place it. Just desolder original broken IC.

Now the oscilloscope works again, thanks again for help!
