Hello guys, good day.
I'm struggling with a SSD Kingspec Raymx RM1135, with no life signal. It does't turn on any status register when powered.
Made some measurements. Both three 6 pin mosfets are receiving 5.1V and delivering 4.7V (U17 and U4) and 1.1V (U18) on outputs.
Don't know what would be the next steps. If someone could please help me. Thank you for any answer.

You have measured the inputs. Now measure the outputs.

fzabkar, Thanks for your reply.
Those are the outputs

L1, L4 and L6 are the outputs. If you really are measuring 5V at the outputs, then the converter ICs are faulty.

Hello guys. I'm comming only to give a feedback.
I've found that one capacitor was shorted and switched it from another equal ssd, and it worked flawless.
Thank you so much fzabkar, as allways a very kind help.
