    I've had my 27" Sony Wega for almost 2 years ago and have finally diagnosed a weird problem with black level in dark scenes when i'm watching dvd's, especially with the 16x9 squeeze).

    I bought some relatively cheap component cables when i bought the tv, since this was the first tv i've ever had that had component inputs (i'd always heard that component was better than s-video, even if on a 27" screen i wouldn't get much more out of it).

    well, last night when it was pitch black inside, i got up close to my tv and changed the inputs on my TV while the different inputs were OFF. My s-video input (switched from my receiver from dreamcast/svhs/dish) was pure black, my composite inputs (playstation and vcr) were pure black, and when i got to my component input (with the DVD player off), the screen was sort of black/blue and there seemed to be alot of low-range interference.

    what gives?

    I have never really been that close the tv in the dark before but i don't understand why there seems to be signal interference with the dvd player OFF in the component input. Did i just buy a cheap cable? is the Wega's component input not a very good one? Should i be using s-video?

    thanks for any info. if i had any more s-video inputs in either the tv (only have one) or my receiver (all out of switched inputs), i'd use my s-video cord but this direct-to-the-tv component hookup shouldn't be looking like this.

    i'd like to add - i have purchased s-video cords from $7 - $70, and the $5 radio shack ones seemed to my eyes to be the best ones, so i will not be persuaded easily that it's just my cords (one of those $7 s-video cords is attached to the TV and is not outputting junk to the tv).

    could it be that it's my DVD player outputting some "junk" when it's off? even with the dvd player PLAYING, now that i look close at the screen more "junk" is being shown in the blacks, that up close seem more blue than my other inputs (even composite). BTW, i have a pioneer 434 (i know, not a great player).

    you'll have to forgive these questions, but i think it will help me when i upgrade to a 16x9 hdtv in march. I need to know if investing in a $200 component cord is much more worth it than a $10 cord, whether the WEGAS have weird component issues, whether it's my Pioneer (which will be a moot point soon when i hopefully buy a Panny RP91 for my new tv this summer)

    thanks

    thanks!

    Yes, cables especially mediocre ones can pick up interference. See if there is any improvement if the cord in question does not pass close to other components or cords or power cords.
    If your "component" video cord has red, yellow, and white plugs, you will get a picture but the quality is unpredictable. Red-yellow-white cables are for composite video and audio, not for component video. If you must use one temporarily, use the yellow plug for Y, the red plug for Pr, and the white plug for Pb.
    If you are lucky, the manufacturer used the same spool of wire for all three lines inside the cord and it was video grade in which case the red-yellow-white cord will work OK.
    Three individual yellow plug video cables will suffice for component video.

    ?? My component cables are standard red/green/blue cables. I'm not using composite cables for my dvd player.

    i'm not saying they're GOOD cables, but they certainly aren't composite.

    are you saying composite cables can actually work in component inputs?
