Hantek 6022BE - Shorted Diode D1

Hello
I somehow damaged my Hantek 6022BE. When i connect it to my computer, the computer switches off.
This must be a short circuit somewhere, correct?
I measured the D1 and it is shorted. Also, pins 1 and 3 of AMS1117 are shorted. the USB pins and the BNC connector are OK, they are not shorted.
if I remove the D1 diode, the short is gone.
so i suspect that this diode is shorted and I have to replce it. can you please tell me the diode type and code?

is there anything else I can check?

thank you

Hello

I have checked. There is NO short between the 4 pins.

thank you!
if I cannot find the smd model, is it ok to use a normal 6.2V Zener?
