Plugging SNES into a new-ish LCD TV

Question

My parents just sent me my old SNES and all the original cables, games, etc., so I'm trying to hook it up to a TV for my wife. I already had tried (and failed) to hook up her SNES to our TVs and just assumed the console was busted, but now I'm not so sure.

Here is the list of parts that I have tried (every combination of them I can think of):

• Two SNES consoles, both first-generation, both thought to be in working condition.
• Two different models of LCD television, one about 3 yrs old, one about 6 mos old.
• Two original RF adapters - one from a NES, one from an SNES - that connect to the RF output on the SNES and the coax input on a TV.
• One aftermarket RF adapter for the SNES/Gamecube that connects to the Multi A/V port on the SNES and the coax input on a TV.
• One original (possibly a Gamecube) A/V cable that connects from the Multi A/V port on the SNES to the composite (yellow/red/white) or S-Video inputs on a TV.
• Four separate games that I believe to be working correctly.

I have hooked up both SNES consoles using all 4 adapters, to both televisions, and I get the exact same behavior every time. The signal that comes across on the TV are thick bands of solid colors scrolling very slowly down the screen (mostly a big green bar that takes up 1/2 the screen with scattered bands of other colors) and an annoying hum from the speakers.

This doesn't seem to match the behavior I have seen reported when things start to go bad. I don't get a black screen, or static, or a somewhat garbled but identifiable signal -- I get this "test pattern" signal on every game I try, no matter what I do. This makes me suspect I have something hooked up wrong or configured wrong on the TV, but I can't figure out what.

Help?

EDIT:

Some additional information here.

• The Composite video cable actually has an S-Video output as well; One of the TVs I am trying to took up to has an S-Video input, and it produces the same result. (And it's possible that this cable came from a Gamecube, as my GC isn't currently hooked up to anything, but I've been told that the SNES and GC use the same MultiA/V output hardware.)
• The first TV I'm trying to use is a Vizio VA26LHDTV10T; the manual for it is online, and there's not much it can do in the way of manually adjusting the input signal.

• When I switch the TV input source to AV, the screen tells me that the incoming signal is 480p SD. Does that sound right? Is the SNES really putting out a 480p signal and not a 240i?

• This is the connector I'm using:

• This is what I'm connecting it to on my TV:

• This is what happens when I turn on the SNES:

Answer

If you have one of the original SNES units you should be able to use the same multi-A/V port Composite + S-video cables that the N64 and Gamecube used, although they may be a little on the difficult side to find now.

I do know that the SNES will work with modern LCD montiors as mine is hooked up right now with a set of Gamecube Composite A/V cables and it works fine.
