Ok, my NES is flikering.... It's been doing it eversince I got it but I was able to make it work in the past. Now, it's impossible. When I turn it It audomatically just starts for like 2 seconds than it stops. It dos that repeatingly and when It's on, the screen is nothing but green. I can't buy another one of the internet because my mom doesn't trust the internet. What should I do?

coming in soon and stuff...
This is NES-dude except now, I'm PG-13! OMG!
