So i went to boot up my original NES and boom i had the blinking red light. So i opened it up, cleaned the pin/insides and cut the 4th pin on the Nes lockout chip. Well this solved the blinking problem but now all i get is a solid yellow screen and sometimes a solid white screen. Did i mess something up or do i need a new 72 pin? It shows the yellow screen no matter if there's a game in there or not and i also cleaned my Nes games before trying them and have tired several different games with no luck. I also tried rebending the pins upwards back to their original positions.
