DSO Shell wont boot up

Post by flowim »

Hi everyone,

I recently bought the DSO Shell DIY Kit model number: 15001K (The one withe pre-soldered SMD parts).
As it is recommended in the User Manual I first connected a 9V power supply to the main board, but it didn't boot up as it should,
so I thougt by myself maybe you have to intall the remaining parts, but it didn't boot up either. So checked the Voltages on the Mainboard.
When I probed between GND and V+ the Voltage was 30mV, as I know it should be about 8,5V (by the way: I checked my power supply. It's working fine.).

So I ordered a new DSO Shell. Although I didn't install the Switches and the Connectors yet, I have exactly the same problem: It wont boot up and the Voltage between GND and V+ is also about 30mV.

I really hope you can help me!
Thanks in advance.

have you tried a 9 volt battery ??

if both units show the same error , most likely the powersupply is wrong.

Tp7 should be your supply voltage ( minus 0.7 volt ) , and Tp 8 should read 3.3 volt
