I really can’t believe what happened. I lent my DSO203 to a friend, who brilliantly did the following connections
127V -> DSO CH A GND -> USB CABLE -> Notebook Grounded
The current came from the ground probe, to the USB ground, to the notebook ground and fried everything in the way.
Please, I really need your help to fix this.
I can notice that the led red light up when I connect the battery.
It is noticible the short in the region of the R47 (Please check the picture)
And something on L8.
I have no idea just by looking at the schematics…
Any ideias? Please…
