Why wouldn't the TV connection work right?

    In Fargo I had the TV connected to the cable box via the RGB cables (three color coded cables, red, green, and blue, for video, plus two, red and white, for audio) and to the DVD player via a single yellow cable for the video and, again, two, red and white, for the audio. Everything worked find.

    When I moved I misplaced the three-cable set, and connected the TV to the DVD player via the RGB cables. (No cable TV here. Nothing worth watching.) But the color was all off. Everything was red. There were still greens and blues in the picture, but everything looked like it was under powerful red lights. I checked carefully and the cables were all connected properly, each to its respective color. RGB component output to RGB component input. The color coding makes it pretty much foolproof.

    I wondered if maybe the DVD player had gotten out of alignment during the move.

    Well, I finally found the three-cable set and connected the TV to the DVD player using that set, to its respective jacks, yellow video output to yellow video input, plus the audio cables, and now the colors are perfect.

    All's well, but I'm curious: Why wouldn't the RGB connection to the DVD player work, when it worked fine from the cable box? (And, yes, I was connecting to a proper RGB component output on the DVD player.) Are there two entirely different and incompatible types of component video, which use exactly the same cables and are labelled the same? Or what? Anybody know what's going on?

    Without crawling behind my TV/DVD/Stereo, I'm just speculating... It sounds like you had the cables right. Red and White are usually Right and Left audio. Yellow video is usually composite video, not component. S-Video is component, but the cable makes connection possible in only the right way.

    Pure speculation, but does your DVD have some setup for HD video? Does your TV really have RGB input? Some systems split the video signal into two channels, chrominance and luminance, for color and tone. Sometimes there are one ot two other connectors, for horizontal and vertical sync, but those are rarely found on consumer equipment.

    I'm glad it's all working again for you. It sounds like you're watching a composite signal over that yellow wire.

    I believe all cables need to be of a higher quality to work in Spokane. Whereas in Fargo, any cheap, supermarket quality cable will work. Thus the lack of cheesy TV programming (oxymoron?) in Spokane. The Spokanites TV show commitee only like to select what they feel are premium programs and these premium programs will only air correctly via high end cables. Don't you remember that roadside DVD player checkpoint as you crossed into WA where they recalibrated your DVD component outputs? :p

    The first thing to check is the integrity of the RGB cables. Maybe during the move the cables were coiled up badly and now have shorts. Test each cable separately from your DVD's composite output and see if each works properly.

    Next, maybe your DVD player's RGB outputs are bad. Have you ever used them before? Try another set of RGB cables and see if the problem still occurs.

    Just wondering, if you have a component DVD player and a TV capable of accepting component, why not take advantage of it? It will improve you DVD viewing experience.

    Lastly, check your menu settings for both your TV and DVD player. Check the input and outputs settings. While I doubt if there's a setting that would create such a problem you described it couldn't hurt to double check.

    It sounds like one of the cables were defective or you did not push the cable in quite enough. You can use the yellow cable in place of each RGB cable to test if one of theRGB cables were bad.

    Thanks for the replies. I am quite certain I had all the cables fully plugged in and connected properly. To look for a possible bad cable (though that seemed unlikely) I switched the red and blue cables. Still connecting R to R, but using the blue cable, and still connecting B to B, but using the red cable. No difference.

    I make the assumption that if the TV and the DVD player have exactly the same labels on the jacks, then they should be the same kind of signal. In this case, a red jack labeled Pr, a blue jack labeled Pb, and a green jack labeled Y. Identical on DVD player and TV.

    Oh, well. Maybe there are, indeed, different video schemes using the same set of jacks. And in the end, I don't really care all that much, as long as I can get a good picture, which I do with the other set of connectors.

    The same thing happened to me a few years ago. I always connected DVD players using composite cables (red, white, yellow). Then, on one set, after connecting a VCR and my kids' game console, I had only the component input for the DVD player and was forced to connect the thing with the RGB component cables. After doing so, colors were whacked UNTIL I discovered the DVD player had a MENU setting and selected "component" as the output for the player. So, as Prius Noir said, check the menu settings on your player.

    Just to point out - in the US, you don't have RGB component output from your consumer video kit. You have component YPbPr. They colour the connectors red, green and blue, but it isn't RGB.

    I second 'tag' opinion. Some DVD players don't have auto-detection capability. You have to switch the menu to output from component video. It happened to me on my Phillips. My Sony, on the other hand, has no such issue. Very puzzling when it happens... :)

    BTW,
    DVI > component > S-Video > composite

    KMO: You are correct. The labels are Y, Pb, and Pr. But they are the same on both the TV and the DVD player, so ought to be compatible with each other.

    Tag: You may very well be right, but I have not been able to find a menu for the DVD player. The Menu button gives me the menu for the DVD being played. And the Setup key just causes a very small circle with a line through it to appear briefly in the corner of the screen.

    'Cheesy TV' would be redundant. 'Reality TV', now that's an oxymoron! :D

    Yep, and I should know better; I've been messing around with this stuff for too long. :lol:

    You might not be able to get into "setup" on your player with a DVD loaded. You might be able to do so without a DVD in the tray, though.

    Also, check setup on your television set. There might be a setting for component in.

    That did it!

    Of course, the picture is no better with component than with composite. But at least I know now why it didn't work. Thanks, Tag.

    (It didn't help any that the DVD player's manual said nothing about this. In the troubleshooting section, under "No color or wrong color" it advised checking the TV's settings!)

    Of course! Vast conspiracy to sell us overpriced sets of cables! :lol:

    Also, of course, we should probably upgrade our equipment so we can see the difference. ;)

    It is curious that a fancy computer cable can cost as much as as DVD player.

    one thing i would have done differently. the connection from the cable to TV is not as critical as the one from TV to DVD so i would have used the component video for TV to DVD and the three composites (yellow red white) for cable to TV provided you are only watching standard cable. for HD cable, the better cabliing is required all around. your picture WILL drop to the level of the weakest link. because DVD's play in a much higher quality format, spend the money on that interface... in most cases, cable to TV can easily be done with the $9.95 cables

    and if you think component video is expensive, i have a DVD recorder that plays professionally recorded DVD's in 1080i upscan (if you have a 1080i capable TV)... it requires a HDMI cable... that cable was $150 for an 8 footer!!

    Yeah, it's ridiculous. I've seen a Sony player, that upconverts to 1080i, selling for less than $150 without the cable while, a few feet away, a Samsung player with roughly the same specs was selling for the same price, cable included. Sheesh!

    There are two forms of component (Y PB Pr) video, progressive and interlaced. I surmise that your TV supports interlaced, but not progressive. Your cable box supports interlaced (and possibly progressive) and your DVD player supports progressive (or at least was set to progressive). That means DVD player on progressive to TV which supports only interlaced = no joy.

    I had a similar issue with my TV (interlaced component input) being driven by my ReplayTV (progressive component output). I would get this odd rolling image.

    I don't have cable TV any more. There's nothing worth watching. The TV is mounted in front of the treadmill and the ONLY time it's on is when I am exercising on the treadmill (either jogging level, or a 3 to 3.5 mph walk up a 10 or 12 percent grade). To avoid sweating on my good glasses, or breaking them should they fall off, I wear polycarbonate goggles, generally sweat-stained. The goggles are fine for what they're for, but they're not my latest prescription. I can see the difference between standard and HD, but not the difference between component and composite cabling.

    I think there is a "Progressive" button on the DVD player's remote. I have not messed with it.

    I'm just happy that the picture is no longer infused with an overwhealming red. I have Tag to thank for that. (Thanks again, Tag.) Now if I could just find some DVD's worth watching for after I finish all these Cirque du Soleil DVDs. Maybe I'll have to go back to watching Roman Dzindzichashvili. It's getting harder and harder to find anything in NetFlix that I want to watch.

    I think I'll start a movie recommendation thread.

    OMG! Believe it or not, years and years ago a friend of mine brought me to a simultaneous tournament sponsored by his chess club and the expert they got was...........Dzindzi!
