dsPIC33EP256MC506 reset after power on

Hello Everyone,
I have difficulty with power-on on my dsPIC.

The problem is that after power-on dsPIC do not reset.
View attachment 107977
MCLR is connected to dsPIC pin. Reset is connected to programmer pin.
I see that when the programmer is connected there it is more often that dsPIC do not start after
power-on.

Before that I had difficulty with PLL, but I have solved it replacing 8MHz crystal to 5MHz one.

Any suggestions?

Best regards,
Chris
