Pak White Salwar Kameez Problem With N64 Expansion Pak?

Problem with n64 expansion pak? - pak white salwar kameez

I have a new expansion pack on my N64 and Yobo did not work so I passed the old and the work now no longer. I have an expansion pack original Nintendo. I'm in and that it does not work. I do not understand what could be the problem. Forces in the system, but nothing appears on the screen only a white flash, then black. The problem is not with the cables, since replaced by new ones.
And I also tryed blowing games and other countries.
