    Did you select component as your input on the TV?

    What the above poster said would be the first thing to check.. The second would be is it really COMPONENT RGB input, or the older type used for computer monitors which I think are different. FWIW, the GREEN cable is the control cable, so if it isnt connected well, none of the others will work. Maybe try downloading a manual for your model and check to make sure its really a component input.

    Secondly, your DVR/receiver will HAVE to be set to 480i for it to work.

    The Red Green Blue on the TV does not = the Yellow Red White on a standard box.

    If I remember correctly, on a Sony Trinitron (nice older tv depending on the size/age) in order to even select the component input, you must go into the tv's menu settings and turn the component input's availability on. My old 300lb JVC has the same setting.

    You can set the box to 480i using the res button on the front.

    What model DirecTV receiver do you have hooked up to the TV?

    Sony made many models of SDTVs with component video inputs, intended for "progressive scan" DVD players. The highest supported format will be 480p. 480i will also work, but not 720p or 1080i, so if the sat receiver is set to one of those higher formats, it won't work.

    They also made many TV's (as well as many other brands did) with component inputs, that did NOT work on progressive scan equipment. (ie: 480i) I still have a 35" XBR that is such an animal...

    Either way, I tend to think this is the OP's problem:

    You'd be surprised how many people seem to think there is NO difference between the two... :eek2:

    That's RGB, which isn't component, and needs more than just three cables. Usually, it needs five cables, and mostly referred to as RBG+HV. The other two cables carry the horizontal and vertical sync.

    And as you said, Green carries the HV sync on component (aka, YPbPr).

    Actually "RGB" is technically a type of analog component signal, and the RGB+HV cords typically with BNC connectors usually occur on one end of a "VGA Break Out" adapter cable with a familiar PC analog HD-15 VGA connector on the other end.

    Correct, and this much more common "component" signal is sort of confusing since the green colored plug and jack actually carries the colorless "Y" luminance or brightness signal with the periodic horizontal and vertical sync added to it. Whereas the other red and blue plugs/connectors carry the "Pr" and Pb "signals which correspond to the R-Y and B-Y chrominance difference primaries respectively.

    I added an HD DVR to my SD TV (an older JVC) just a few days ago. When I tried to setup the DVR with the component cables, I wasn't getting an image at all. I ended up having to use an S-Video cable to get the DVR setup started and then switched to the component input. I got an image, but it was a weird split screen. It wasn't until I had finished the complete setup and had changed the video settings to the proper ratio (4x3 for my old box) with only 480i being supported that I could get the proper image through the component cable. Hopefully it's something easy like this for you as well.

    I used to use the component outputs on DirecTV HD-DVRs hooked up SDTVs, but now use only the s-video because frankly I could not see any PQ difference between 480i component and s-video and for some reason found the s-video signal to be somewhat brighter.

    I was also tired of temporarily losing the picture during receiver resets or firmware updates since for some reason the HD-DVRs always default to 480P on the component (and HDMI) outputs during these operations.

    Mostly true, but not 100% accurate. I recently retired (and sold) a Sony 60" CRT rear-projection TV that had component inputs. It was purchased sometime in 1999 or 2000, long before the standards had finished settling.

    Anyway, the component inputs would accept 480i, 480p, and 1080i (no 720p for some reason, likely due to the standards still being settled, like I mentioned). In addition, my current DLP units will accept any HD signal up through 1080i (no 1080p) on component inputs.

    Component video cables are capable of sending a higher resolution signal than 480i/480p, but the equipment needs to support it. Most likely, an older CRT Sony Trinitron doesn't, but a blanket statement about what standards component video cables can or will carry will likely be inaccurate. The only way to know for sure is to read the documentation or specs about the devices at both ends of that connection.

    The first HDTV I got was a Panasonic 47 inch rear projection and all it had was component. I watched the few 1080i shows there were back then around 2000 on Directv in 1080i on it. It would also do 480p and i but no 720p
