Hello,
I had a problem with CH2 in my Hantek Oscilloscope.
First picture shows wave from PROBE COMP ~5V@1KHz connector.
.

The second picture shows CH1 and CH2 probe less.

Please Help.

Did You had any idea what element can damage?
I can not give back to the seller.

Sir, please move CH2 up and down, will the waveform move along with it?
