Soooo, I know it may seem a tad weird to post a problem with a 20-year-old console, but I recently got it back from my brother, and it was working fine up until today.
I have my SNES hooked up via A/V (yellow, white, and red input/output cables) to a non-HD, non-flat television and up until this point it has worked flawlessly. Today, I tired to play some Donkey Kong Country 3 only to be greeted with the opening theme, but no opening video. Just a blank, black screen all the way through. I tried multiple games, and sure enough, it wasn't a problem with the cartridge. I then tried it on another TV, and saw that while the video does not display any better, that the screen does change from its default hue into the blank, black color as in the other TV.
Thinking it was a problem with the cables, I tried another set of (all Nintendo-made) A/V cables and the results were the same. I then tried multiple consoles with the same cables, and every other console worked like brand new with all the cables I owned. I finally brought out the old RF cables which I haven't used for about ten years and found that one of the RF cables I have does nothing but thicken the static (on the alternate TV, which is not connected to cable) whilst another RF cable brings up the same problem with the A/V cables. Audio, but nothing but a black screen.
So after cursing and physical brutality failed to yield results, I resorted to pleading and threatening to cry to no avail, and while I was considering eating a whole tub of chocolate ice cream right in front of its face to make it feel sorry for me, I suddenly remember I preferred mint chocolate chip, and having just run out of it, I was finally completely out of ideas and decided to do some research of my own. Unfortunately, every message board thread and every HTML page and every PDF of the Super Nintendo instruction manual that I already have all left the problem addressed, but completely unresolved... that is, when the problem wasn't the opposite of my own problem.
So yeah, I have no idea what to do, so if anyone can provide any assistance or advice or suggestions for delicious comfort food on how to remedy this situation, I'd be VERY appreciative. Thanks in advance!
