What problems ))

Hi!
I am still waiting for my DSO2C10. With a little luck I'll have it in two weeks.
Could you describe what exactly you changed (schematic or photo?) and what exact components you used as replacements?
Since your changes were obviously successful, that would be interesting. I'm a newbie at this sort of things.
Thank you.

In other words, is it worth hacking it?

the main purpose of this hacking is unlock AWG which was hidden on cheaper C10 version.

No .... these kind of scope should never give you analog image quality.
I think with DSO you should choose the one with Digital Phosphor technology (like SPO/Siglent or Ultra Vision/Rigol) for better result and faster waveform capture/display rate.
I hate the laggy on Hantek especially when opening Measuring (only 1-2 parameters like RMS or Freq) on the display.

Got a 2C15 a few months ago (Now a 2D15 after sending the SCPI commands to turn on WAVE GEN)

One thing I have noticed about the LCD screen on my Hantek DSO is
the change in contrast when changing vertical viewing angle.
See attached picture.
Upper screenshot was taken when viewing LCD pretty much straight on at right angle.
Lower screenshot is viewing from somewhat above the screen.
 (This is my normal viewing angle when scope is on my desk).
The non zoomed portion of the waveform is almost invisible.
I have noticed this problem only with DISPLAY PERSISTENCE and the Horizontal Zoom features,
 not sure if this highlighting/non-highlighting is done other places in the menus.
SW is 1.0.3.0.0(20230327)
FW is 3202

For now I'll probably prop the front feet up on something to fix the viewing angle.

Is there a contrast adjustment on the internal LCD panel?
(The DISPLAY menu shows just Intensity and Brightness)

DavidAlfa:
No contrast adjustment. Use the bottom legs to adjust the viewing angle.
This screen is actually pretty decent!

Have you tried overclocking? Not a miracle but helps.
Most will get around 684-720MHz just fine.
