Sorry for the miscommunication.

Can you please provide the voltages from TP4 on the power board, TP1 and TP4 on the main board so that we can further debug the issue.

Best regards,

i connect  only dc 12v adapter

the  set jumpers  on power board is j6,j7,j9  are open  j14 close  then i connect ground TP1 and  v TP4  get 0 v

the  set jumpers  on main board  is j2,j3,j4 short 1,2 j6 short 2,3 j5 and j7 open  connect ground to TP16 and v to TP1  and TP4  get 0 v

on  power board j3  i messurure  the v is =12.25v


could we arrange  meeting  with share screen  it will easier to explain the issue or further investigation
