New Hantek DSO2X1X models?

DavidAlfa:
Leg fix. Drilled the 3d print, melted a M3 insert in and used a large washer to spread the tension evenly.
(Yeah the printer needs some retraction tweaking, this is petg not pla).

Seems pretty solid!

Hi, I have the DSO2D15 and some button aren't working properly, for instance the single button can trigger all of these other buttons :

I updated the firmware but it didn't help, I'm gonna contact the seller I bought it from... In case they don't want to fix or replace my scope, do you guys have any idea how to fix it ? I never opened it before but this type of issue looks like a bad ribbon somewhere ?
Thanks for your help

DavidAlfa:
The buttons are all sampled using three wires (Scan reset, Scan data, Scan clock), it might be a bad ribbon  onnection or a solder defect, luckly for you the button board is very simple, there're only 3 ics and few resistors.

I don't think it's the ribbon, otherwise you would get nothing or random input, not exactly the same buttons everytime.

Thanks to @Pcprogrammer (He fully reverse enginneered everything) we have schematics:

Looks like only one column is working? (See attached picture).
Thus, I'd start by checking U2 and its connections, specially pins A,B,C (9,10,11).
Then check U1 (Ripple counter) and ensure all its outputs are toggling on/off at several KHz.
I recall seeing a 600kHz signal in key master clock.

hi, there!...

i want to add a fan to my hantek oscilloscope dso2d10, so please, if any one know the size of fan that fit, please let me know...
i want to buy one whitout teardown it...;-)

many thanks and electronics greeting from spain

DavidAlfa:
Not required and possibly another source of electrical noise for an already wonky design, I wouldn't do it, but you only need to remove the 4 screws holding the back to check the dimensions, no need to put it to pieces.

Or use the search button!
