Question No color when using Component video on LCD RPTV

I just recently picked up a new Mitsubishi WD-52531 LCD rear projection television set and went to plug my old Xbox into it using component cables. After hooking it up and turning it on, I was surprised to see that the picture was in grayscale. This problem appears in both component ports and at any resolution (480i/p, 720p, 1080i). Here's the interesting part: I am unable to replicate the problem hooking this console up to a different television using the same cable. I have already tested the component inputs on the Mitsubishi using another device and confirmed that they are working properly. I have hooked up this console to other Mitsubishi digital rear projection televisions in the past with no problems.

Why would a television with confirmed working component ports hooked up to a confirmed working console with a confirmed working video cable yield this kind of result?

Double-check your connections. It's possible that a plug wasn't fully seated.

I triple checked them. Besides, if I'm seeing a picture at all, doesn't that indicate the successful connection of the Y (green)? And shouldn't I be seeing at least an image with a green tint even if the other two leads weren't connected?

Of the three component cables, the Y is not really the green in the picture, but all the luminosity information - red and blue (PrPb) carry the differences in color for that signal.

check to see that you haven't mixed colors (easy to do) on the plugs and jacks. For example, make sure you're not confusing blue and green and that you are using the red component and not the red audio plug/jack.

Edit: Wait, you are using all three component wires? You're not trying to plug a Composite (yellow video) output into a Component (green "Y") jack, correct?

I appreciate the diagram, but believe me, I know the difference between component and composite and how to not plug the sound lead into the "Pr" port. Like I said, I have successfully plugged this in to numerous other televisions without issue. For the record, the set is actually recognizing 720p HD video as well from the Xbox (not Xbox 360), as is the other television that I have plugged it in to with no issues. It's only on this one Mitsubishi.

Have you used all three conductors, inserted in the green jacks, to check for image? If you lose one, your color will be either wrong, or non-existent. Safe to assume the TV only has one Component input? Molded ends, or made for this installation?

Thumbs up Happy ending

Ah ha! I figured it out. Turns out, those monster cables grip the port extremely tightly, so while I thought I had them plugged in all the way, I indeed did not have them plugged in all the way. It worked easier on the other television because the ports weren't quite as tight as the Mitsubishi's. Guess it was user error all along.

That's what I asked you to check in my first post.

I'm glad you got it straightened out. Have fun with it!
