I have had my SNES for a long time now. Working properly for as long as I've had it. And now I have no sound but everything else is working fine. I've tried more than one Video Cable. And a RF Switch just to be sure. And nothing. I hope someone can help me with my problem. Thanks.

Re: Picture but no Sound
Its a common problem with those old machines. You can open it up and re solder the input connection and check the circuits to see if any others need the same treatment. If you are not confident doing this, I am sure that it can be done cheap by someone qualified if you look around a little.

It is possible that you will need new cords. (It sounds like you power cord has a short in the cable somewhere, so it may need replaced too.) A new video cable may fix the problem, but if it doesn't, the SNES may be on its las legs. In that case, you will need to purchase a new SNES or just turn up the brightness on the TV.
I am guessing that it sounds like it is a glitch then with your SNES console try cleaning the game packs out with rubbing alcohol and quips same thing goes for the game pack reader too. The worst case scenario is that the console is on its way out or the graphics chip is not working properly.
Maybe the one that is not turning on to play game is broken then. 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.
The problem is likely in the IC soldered to your SNES circuitboard. The cheapest way to solve your problem is to replace the whole SNES circuitboard. These boards run about 20 dollars, Google part SNSPT007 or SNSPT009, depending upon if you have the older or newer version SNES. There is no soldering involved, so it should be an easy fix if you can open your SNES.
I'm having the same problem currently actually...wtf SNES! I actually bought a second SNES because I thought my old one was permanently broken but as soon as I got the NEW one in the house the OLD one booted back up... the only thing I can guess is that it burns out from time to time because of the age.
Well it might be an issue with the av cables or the rf switch or the tv its self. One time I plugged my SNES console into the rya jacks for video 2 and the screen was in black grey and white but I tried it on video 1 with my av cable and channel 3 for my rf switch and it was fine. It could be the problem that i had.
