I use Timer1 Ch1 Ch2 Ch3 Ch4 in PWM mode 1, configured by Cube MX. But Ch2 and Ch3 do not work. Ch1 and Ch4 works perfect. With the same config stm32f407 works completely perfect. Does any one know something about the problem.

Which pins? On what hardware?

Read out and check/post the TIM and relevant GPIO registers content.
