Why do my NES and SNES display wavey lines on the screen?

[BocoDragon]

I know this is a technical question, but I've asked it before in the other message board and it's been buried... I think it's a question that has an answer:

Why do my NES and SNES display wavey lines on my 27" Wega, as opposed to my modern consoles which look fine? They're connected by completely different and high quality cables. (composite and s-video)

1. Was it always like this and picture quality didn't get better until later consoles? Do I need to get used to it?

2. Is this dirty power, fixable with a clean power bar?

3. Is this something else?

Please help someone! NES and SNES look crummy on my TV, and everything else looks great.... even a PC emulator running NES and SNES games (sadly, I might add)

It could be improper shielding on the systems.

The NES has its RF metal shield... that's what you mean right? I would assume the SNES does as well... or could something go wrong even without someone actually opening it up and removing it?

Have you hooked the NES up to the TV via the AV on the side of the NES?

Are you using an RF switch,could be a faulty RF switch..


How are the systems hooked up to the TV?...
Are you using known to be good hook-ups..(RCA jacks,AV wires)

Are you using a secondary device to run the systems through to the TV,like system selector..?

Can you try the systems on another 27 inch TV..?(I'd try this first)
How do the systems work on other TV's?

IMO it could be a old system to TV compatibility issue ...I feel that with some TVs,older systems don't work well on them..

I have a 25 inch Quasar TV that older systems like NES/SNES won't play right on..I get static lines when using an RF...
But if I hook up the same system an RF to another TV they work fine....

If none of what people sugguested so far try a new av or audio video hookup. Also you can try wiggling the wire that attach to the tv if that makes it worse and sometimes better something isn't good with the cable. Furthermore I would make sure the only device you have hooked up to the tv is your snes or nes cause the more things you hook up and daisy chain you can get some degratation and lose of signal. Give a shout if that works or what not.

Black bars on the sides? Is it a widescreen or 4:3 tv?

4:3 tv it should fill the screen.. widescree it should have black bars on the side unless you pick the option on your tv to stretch the image.

As to sheilding.. try moving the consoles as far back from the tv as possible.

Also, these old systems run at 480i.... if your tv is on 480P or something higher, you might have to adjust the television.

Good Luck.

Also to add I know I"ve had problems minor before with cables that give wavy lines and such good luck let us know what you come up with cause there is bound to be others that would like to know as well its more a common problem with the older gen systems

But they can be made to work better as well.

Overscan. Or in this case, underscan? LOL

Basically the TVs back when the systems were released didn't show the entire picture, they always cropped out the edges. Your TV is newer, so I'm guessing the screen was not adjusted like these old sets and you can see the edges of the screen.
