Why do I have no image?
My SNES powers on but I cannot see any image on my tv. I have tried the rca cables as well as the coaxial cable and still nothing.
The Super Nintendo Entertainment System (SNES), or simply the Super Nintendo, is a 16bit gaming console released by Nintendo in 1990. The Super Nintendo was one of the best sellers of its time and still has a large fanbase today.
Ensure that you have a known-good game cartridge inserted before powering on the SNES console. Most older, cartridge-based game consoles don't boot without a game installed.
Does the power light to the left of the controller ports turn on when you turn on the power switch?
If not, check your power adapter and outlet for functionality and good connection.
Check that the reset switch is not stuck. Wiggle it back and forth through its range of motion a few times. If something sticky gets in there it can get jammed in the reset position, which will prevent any game from booting.
You mentioned that there is no image. Are you getting any sound from your games after waiting a few minutes with everything connected and turned on?
If you hear game sounds or music from the SNES, but see no picture and you've already (really and truly) ruled out the cabling and TV, then you might have a bad main board in the console.
If you don't get any video or sound, then it's not booting your game. You can find other recommendations about how to clean game and console connections, but usually inserting and ejecting a game 10-20 times will knock loose or grind off enough gunk to get a game to boot. Try this, and be sure to use the eject lever instead of ripping the game out to avoid console connector damage. If it's still not working, repeat with another game.
I've been working on this issue for the last few months and I'll tell my findings so far so whoever is googling this answer might have success finding the root of the problem.
Got a SNES console, originally it booted on with just a black screen. No sound, no picture. So I checked some forums out and a bunch of them said to deep-clean the console because it might just be a bad pin connection. Opened up the console, revealed the pin connector, cleaned it out with 99% isopropyl alcohol (Costco, 10$ gets you 4 good-sized bottles of the stuff,) as well as the contacts on the board where the Pin connector joins in. Turns out there was all sorts of dust and bits of debris in there, and once I cleaned it all up.. It turns on and boots the game!
Open up your system. Clean the pin connector.
Problem #2.... now the system starts up and loads any game I shove into it, but it only plays for a minute or two then randomly shuts the game off but the power is still flowing to the system (Red light is still on)
This is the current issue I'm having with one system.
Other suggestions I've come across are that the PPU or the VRAM chips might be burned out on the motherboard, or one of the video caps has decided to die. Video caps however are extremely easy to replace if you've ever done some minor soldering before, so check to see if any of the caps or bloated/burned out/look dead and then try replacing those.
If it's a PPU or VRAM chip... I'm not quite sure how to fix that yet. Working on it.
Good luck to all your folks out there.
I know this post is super old but I had the same issue and I found a fix. Turns out the power cord was bad even though the little red power light went on. I must have been getting enough power for the light but not enough to turn on the system. Hope this helps somebody.
Hello, my problem is that I got a snes and when I turned it on and I find that the screen turns black in both video and channel, take apart, clean the connector with isopropyl alcohol, check that the board is not short, check the fuse, try another source and various games.
But the failure persists, when turning the console on and off, note that it emits a download sound and the screen goes black as if receiving a signal.
any of you have any idea what else can it be?
