Sorry I realized that I couldn't manage to attach a pic in my first message. I have now, would you please have a look at it? They look pretty burned.

C74, C61, RV7 and R2 are definitely not working.

That discoloration is just solder flux that was not washed off well. it might also interfere with meter probes if they do not have very sharp points to poke through the residue.

Hello Everyone,

I'm new to this forum and this is my first post.
I have bought a Da Vinci AIO 1.0 last week. When turned on, the power supply just runs for a second then shuts itself off. I've removed the power connectors and tried to connect 12V, 5V and 3V one by one. 12 and 5 are working fine but the power supply shuts off as soon as I hook the 3V up. I've then inspected the board and found some resistors not working. How may I identify these resistors so I can replace those? Thank you in advance.

If they are not burnt the values should be right on them.
