Why Is My Nes Turn Grey And Won T Read Games Wont Read Ducktales Nintendo Entertainment System

Chosen Solution

Hello. I have a NES that works, but when I use the AV input on my Sony Wega, it wont read the game and the screen is grey. I’ve cleaned everything and it still won’t work. I have Godzilla 2 and Super Mario Bros but they too dont work. All my games don’t.
