Green Lines on my SNES Screen

[Battroid]

Hi All. I hope I'm not repeating an old thread. I just got my old SNES up and running. Unfortunately there are green lines running continuously down my screen. I tried 2 different tvs. I also tried both RCA connections and the RF connector. Anybody know how to fix this problem? Thanks!

Replace the aftermarket AC adapter with an official Nintendo one.

Curses! -shakes fist- You know, I kinda suspected that might be the problem. Ok. I'll look for the real deal. Thank you so much for your help.
