Hi Guys,

I got this PCB here and did some testing.
I am not getting 320VDC on the big cap.
That relay KT1 is not clicking through, so I am not getting anything on the bridge rectifier.

I got 320VDC on the smaller cap after the small bridge rectifier.

Can anyone give me further tips how and what to test?

I am assuming the mosfet to the right (L30P70 0B2338SP) might be the issue.

Sorry for the pic, I have a subpar phone.

Thank you guys in advance.

The other side of that board.

Please let me know if the pictures are not good enough.
Then I will borrow a different phone and take new ones.
Thanks

Do you know how I can make sure it works correctly?
