I really appreciate your time, unfortunately it's still the same, I tried to write it with two programmers and the macbook still doesn't turn on, the fan only works for 10 seconds and doesn't give an image,

This is a process that these logic board turns on. Just wait, & let the logic board do all it posts test till you get the display after about 1~2 min & all should be fine. If not then check you logic board, check for any shorts or anything abnormal on the board.
