Nes Solid Yellow Screen

[Intimidator80]

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.

I have the exact same problem. Did you get it fixed?

The yellow and white screens are an indication that either the cartridge or cartridge slot needs to be cleaned.

You could try an old method I used before bending the pins back on the 72 pin connector, take a game genie and put a game in it. If your game start without issues your 72 pin connector needs to be replaced or you need to bend the pins back
