    THE PROBLEM IS WE DONT HAVE SUPPLY TO THE 4 IGBT's ALSO THE DIODE AND THE 4 BIG CAPACITOR

    Assuming you have power input and the two fuses are OK and that there is no power reaching the big bridge rectifier (on the other side of the board) look carefully at the tracks and the solder joints between the input and the bridge. Also there should a common mode choke which you should check. That might be the large black rectangle about half way up the board from the fuses.

    The route from the fuses to the bridge rectifier should be short and obvious to trace.
    Do a little reverse-engineering and it should may be clear it up?

    Yeah, you will need to follow the tracks and see how the power is supposed to get to the rectifier, then you can check where the problem is.

    The join connection is good.

    So you need to get the meter out and see where the connection from power input to rectifier fails.

    Unfortunately not for that board.
    But as two of us has said, do a little reverse engineering, do you have a meter?
    There cannot be too much between power in and the bridge.
