If you can get red from one of the other channels then your tv is fine. It's just a matter of getting the right signals and the right settings. There is a manual here for the TX-68p250z, which has the same "RGB 31.5 khz" connector: http://www.google.com/url?sa=t&source=web&cd=9&ved=0CFYQFjAI&url=http%3A%2F%2Fwww.elektroda.pl%2Frtvforum%2Fdownload.php%3Fid%3D357972&ei=u1H-TZWzEsXl0QGZvsDdAw&usg=AFQjCNFB7EV7cPMXIJTlEblQX780fuousw According to the manual you are doing everything right. You need to look all over and see if you can find anything about switching Component, also known as YpBpR, to RGB. Any kind of external switch or button, some kind of option in the menus. You can try other stuff like the other DVI input on your card, different DVI-VGA adapters, etc. It would be very helpful to try a VGA source that you know for sure can't output component video. Does the Nvidia control panel recognize the monitor? |

It's certainly possible, but unlikely as the diagram in the manual doesn't mention it. It could be that the TV is just not compatible with certain graphic cards, and the OP has been unlucky enough to have two computers that won't work. I've had a few different "pro" monitors that had issues with newer Nvidia cards, from having green screens to just showing nothing at all. My suggestion is to just try more sources. If you look at that screen shot of Mortal Kombat running you can see the match timer is all black. If he had a bent or missing pin then it would just be colored a mix of blue and green. But if you send component over RGB then it actually does get some red signal and it makes this weird dark, dark, reddish black. |

Tear the two DDC pins out of a VGA cable (that you don't care about otherwise), hook it up, and force everything to 640x480p. Windows should just identify it as a "non-plug and play monitor" and pretty much go into dumb, "I'll do whatever you say, boss, because I have no idea what you've hooked me up to" mode. Verify that you're gettting all three colors, with the same cable, on a PC monitor, then swap over to the TV. |

well now, I figured i'd try booting into linux(my main OS) this morning to see if there was a difference in how it handled the output..... low and behold we have red!! i used the DVI to VGA cable i had. Was about to write a quick reply saying how hopeless windows was but thought i'd better try it again.... so booted back into XP and the picture was all good as well.....mmmmm Had to head off to work so couldn't test any further, but it leaves a few unanswered questions?? |
