SNES color bleeding?

[drkssence]

I just purchased a used SNES, but I'm having some issues after turning it on to test out the games. All of the games seem to have some sort of strange color bleeding or colored lines either in the menus or in-game. I don't have this issue with my Genesis, so I can't imagine it's my TV. Does anyone know the cause of this? If it's the games, cables, or the system itself? Should I just return it or is it an easy/cheap fix?

Thanks!!

-EDIT- I should also point out that I also tried using my N64's video cables as well, so its doubtful those are the issue.

if its returnable I would return it.
what are some other games it bleeds in?

its hard to say exactly but from what I have seen online and in person before it could be bad vram or a bad ppu/gpu (which ever you want to call it) possibly encoder too but if its a one chip snes then its kinda just effed any way
