Colors not as bright when using component?

    Well, after some trials and tribulations, and mainly reading the manual line by line, I corrected one of the problems I was having with my new Onkyo 755 setup. http://www.hometheaterforum.com/htfo...hreadid=119914


    And that problem was with the progressive scan splitting the screen into two warped half screens. I had the component video plugged into the wrong input (only AV4 on the Philips 34PW9847 handles 480p).

    Problem now: The colors displayed through the component connection are not nearly as bright and vibrant as they are through the composite or S-video connections (if I switch between them).

    This isn’t just a little noticeable, but very big differences. The component connections are much darker almost as if there was a thin black film covering the screen. The crispness is still there but not the color.

    Has anybody else had this problem with a Philips TV or with another brand?

    I tried playing with the contrast, brightness, and color settings on the composite connection but no luck.

    Any thoughts would be appreciated.

    Bob,

    Thanks for the quick response.

    - DVD to TV with cable one: Problem Y/N
    - DVD to TV with cable two: Problem Y/N

    I tried connecting the DVD player directly to the TV using both of the component cables I have (Monster). Same problem.

    - XBox progressive to TV with XBox cable: Problem Y/N
    (or find another progressive DVD player)

    The Xbox is not progressive, but will try to borrow another progressive DVD player from someone.

    However, the same lack of color happens if I have the DVD player set to interlaced rather than progressive (there setting to switch).


    - Macrovision
    That's kind of weird. Understandable, but weird, I will contact Onkyo about that one.


    Note: In my previous thread, I had said that I had hooked everything up to AV4, but it was actually hooked up to AV3. That was the problem.

    Though this may not be your whole problem, I figure it's worth mentioning. Many DVD players output 7.5 IRE as the lowest black level on S-video and composite feeds but 0 IRE as the lowest on component. This will make the picture seem darker, but shouldn't affect color.

    I assume your s-video and component are using two different video settings on your display device. If so, you can calibrate both of them one at a time and it should yield the same results.

    Hmm, Calibrate each input? Sounds like good advice.

    The way I see it is that: when a vid sig is combined there is some decoding (separation circuit) that can input it's own signature. same but to a lesser degree s-vid. Separate the RGB (red, blue and green) signal as in component and it's a " truer" signal, but you have to tweak it for your viewing pleasure. Have you run any calibration or even adjusted for viewing?

    Calibration is definitely the first thing I would check. I noticed a difference right away when switching from s-vid to component, verified by a recalibration which required changes to my settings.

    Thanks for the responses and suggestions. My internet connection has been messed up for the past several days or I would have replied sooner.


    I started recalibrating the video settings on the AV4 input and it corrected the lack of color/black hue issues.

    After reading through the manual that came with the TV a number of times, it doesn't mention any where that you can (or have to) adjust the settings for each AV input seperately. Without you guys suggesting it, I'm not sure I would have ever thought to try it.

    I'm still having the Macrovision thing, but will call Onkyo shortly about it -- have to leave for a business trip on Tuesday for a week and a half. I sent them an email about it last week, but am not holding my breath for a reply.

    Thanks again for the ideas. Now all I need is the Avia calibration kit, to really improve it.

    Hey I have the same problem. I have a Sony DVD (not progressive) and a Panasonic 27 inch gaoo. The same thing happens when I hook up with component cables. When I calibrated with Avia with the color adjustment turned up all the way and looking through the blue filter it was not even on the scale. Using s-vid and calibrating it works fine. A little bit of red push but nothing I cant live with. I have tried a different dvd player with the same result. I have not had a chance to test the cables or the TV. I have also tried going into the service menu to see if I could adjust the component input separately from the others with no luck. I am hoping its the cables, because they are much cheaper to replace then the TV.
