Stairs or Teeth Effect with Video on NES
I have purchased NES from an online store and when I am playing games, it has some weird stairs effect, like every next line shifts with 1 pixel and then after 8, it goes back. On the letters/text it looks really bad. It is the same using Composite and NESRGB:
There are also weird yellowish shadows on the objects:
Any ideas about what it could be and what to try to figure it out?
