Topic: Lines on SNES TV Screen

i decided to play my snes and every time i tried to play a game they would have black and grey vertical lines and dots all over the screen I've tried many different games and it happened to all of them ive tried both av cables and rf both had same results we have also tried both an HD tv and a CRT same results with both. what can i do to fix this?

If you're playing on an HD TV you might want to try playing on an older TV.

Is it the first model SNES or the second model? What kind of cables are you using?

first model and the cables i used are mentioned in the question

Sounds like your SNES may be "dirty". If you can clean the console pin contacts, do it. It might be the cables, but since you mentioned that it's happening with both A/V and RF, it's more likely the console itself.

If cleaning the console's pin contacts doesn't work, then there's probably a blown resistor or something, and if that's case then you're going to need a new SNES.
