PWM 1, 3 and 4 pins not working on dsPIC33EP

Hello everyone, Im developing a project on dsPIC33EP512GM710 and everything ok but im surprised when I was configuring the PWM module, the pins associated does not work, only on PWM2 I got signal, JTAG Off is set and tried everything, disabling PMP module, ANSEL, TRIS, PWM unlock etc, the pins not work in I/O mode so the problem is the pins configuration but I tried al I know, the pins are RB10, RB11, RB14 , RB15 and possibly any others , on datasheet that pins are marked as Output so I dont undestand, can anyone help me? Thank you very much

    Check the PWMLOCK configuration bit state. If it's not set to 0, certain PWM registers may only be written after a key sequence thus effectively disabling the related PWM functionality.

    Thank you for reply, as I said, the PWM is unlocked via #pragma config PWMLOCK = OFF , I dont know what is wrong with that pins, putting a single toggle on the pins shows me an output so the problem now is directly related to the PWM module
