Hantek 1008C 230V on oscilloscope ground
« on: September 30, 2018, 08:13:57 am »
Hi,
I accidentally shorted 230V to negative lead of my oscilloscope while doing some measurements. My laptop(PCH) and hantek both are dead.... on hantek board i can see that C410 was completely blown away, near L413 is showing ohms instead mH(measured with element tester), I can't find any service manual for this board, maybe someone could measure their C410, L413 and post photo of R15 which seems to be damaged aswell and can't be identified. Might be other damage that i cannot see right away. I'm not very experienced with troubleshooting electronics so any advice is welcome. Sorry for bad english.


//Edit : 1

R15 is X10 - fixed
U3 is ASM11177 - fixed i got 3.3V back
Still not recognized usb device, still no diode
One HC595 looks damaged.
Starting to think it's not worth to trace everything.
