Problem with Build : HV Led wont turn on / Only 7V Voltage

[dwelltime]

Hello

I have some issues with building this nice device.all parts were used from the bom list except RGT16BM65DT i used instead IKD06N60RATMA1.

Gerber files used were rev04_normal.zip also with milled slots for the protection shield.
>> i ordered the boards from JLCPCB

The solder orientation for the LEDs wasnt so clear to me,so i modified the micropython firmware to run a LED check on startup which works great.

So the actual problem :

The test header (J3) shows only 7V when the ARM button is pressed but the HV LED wont turn on so Pulse doesnt work either.Voltage on (P3) is approx 3V which seems to be correct.Discharge button works.

I looked at the firmware and changed the PWM duty which seems also to work i gained then 12V but its still alot missing hehe

Somewhere i did an error i think but i also rechecked already the solder orientation for the different smd parts.
So can anyone please point me in the right direction and give me some hint?

Should i maybe test the C Firmware? But there is also still some issue with the arming button ive read.
>> so i compiled the C Firmware and that isnt the Problem.The Arm Button still has issue.

Thanks
