Good day Wangshuang!
Need your help! I bought a hantek 6074 from Wiysond TECH. Shop (Aliexpress.com).  Everything was fine –the machine worked. I recently misused the device and screwed up (High voltage - 220-250V) was applied to the entrance. The device needs repair! Local services refuse to repair due to the lack of electrical circuits of the device ... Official dealers (selling Hantek products in Russia) also refuse to repair, as the goods were not purchased from them. Unfortunately, I was not able to find the scheme of the device on the Internet, so I ask for your help - could you send me the basic electrical scheme of the device (or tell me where to download it) to perform repairs.
On this portal reread a lot of messages concerning the faults Hantek 6074BE - I think you are very competent in this matter!
I look forward to your help!
(Sorry for my English - I use a translator program)
With respect!

I made a mistake, my Hantek is called DSO4204C.
DSO4202C was wrong.

Hello,

I have a problem with my DSO4202C. After I made a firmware update, my DSO4202C shows whether it was DSO4254B.
Update was downloaded here http://hantek.com.cn/products/detail/12167
My function generator is deactivated.

Serial number has been changed to CN1951001004117.
Original serial number is CN1813002001744.

Could you please help me?

Photos attached...

thank you
