That's the "PPU open bus" pattern. You assuredly broke something else - the 74'373 or the 74'04 - at the same time.

I did 20 times unlock region but this time is first when have glitches. Always cuted this 4th leg without problem. Before cut I checked this nes and after this cuted. I think problem was from rest power on pcb?
