Hi my name is Jose,
I have an oscilloscope Hantek DSO1200. I was measuring with my oscilloscope and suddenly stop measuring and the signal line began appears on the top of the screen. I checked the system setting, reset the device and it continous with the same problem. The channel 2 works perfectly but not CH1.
It seems that it's an electronics failure... How can I solve? What kind of checks can I do?
I attached a pic with the osccilloscope measuring. Thanks so much a greeting.

Hi again,
I'm looking for the chip and I can't find it. Do you know where can I buy it?
Thanks so much.

Hi!
I replaced the chip U30 SST5912LF and it works! but the channel offset changed, 600mV on top. Do you know if can I adjust it?
Thanks so much, a greeting.

Sir, did you do self calibration after you replace the chip?
If not, please disconnect and probe a ...

I tried that and now it works perfectly! It was solved.
thanks so much for your help!
