Midas MC42005A6W-FPTLW3-V2 does not initialize

I have been struggling for two weeks to get a SPL780D based LCD to work. I checked the wiring and the code with the timers many times, based on the datasheet and a lot of examples. Alone, and with other people.

I use this function to send instructions to the LCD

    void send(int rs, int rw, unsigned char db)

    {

        RS = rs;

        RW = rw;

        wait(1000);//26ms

        E = 1;

        wait_k(1000);

        DB0 = (db & (1 << 0)) ? 1:0;

        DB1 = (db & (1 << 1)) ? 1:0;

        DB2 = (db & (1 << 2)) ? 1:0;

        DB3 = (db & (1 << 3)) ? 1:0;

           DB4 = (db & (1 << 4)) ? 1:0;

        DB5 = (db & (1 << 5)) ? 1:0;

        DB6 = (db & (1 << 6)) ? 1:0;

        DB7 = (db & (1 << 7)) ? 1:0;

        wait_k(1000);

        E = 0;

    }

I tried many other delays, and I follow the sequence below :

Can someone please help me ? Launching the sequence makes the screen blink once, and then I only have two lines of black boxes.

I am starting to think it is broken.
