Hantek DSO5102P CH2 Failure (bis)

ghs

Hi,
My DSO5102P's second channel doesn't work anymore: it reads -104V from its generator, and -4.24V when I probed the ground. Self-calibration yields error code 0x10c00 and I can't return it... Could you tell me which parts I should replace, please?

Sir, sorry, we do not see the motherboard, we can not judge the specific problems.

Hello,
Here are the picture I' finally took: https://drive.google.com/drive/f ... g9Y8G8FG6K-vlRbr2ps. It looks like I've fried a relay...

It's the average, as you can see on gen_ch2.jpg and zero_ch2.jpg.
