My brother in-law has asked me to post this here in hopes that someone can help.

He has a EVGA GForce 8800 GTS

I am going to paste his emails below.

Here's the complete description of the problem and all attempted solutions. See what you can find out, please. I'm gonna do more research, and I'll let you know if I solve it. Thanks, bro!

First off, any past experiences I mention involve the exact video card currently in use (EVGA Geforce 8800 GT) and therefore the card is capable. I constantly have the tv in the room with the computer hooked up to the computer via composite cable. I never have any trouble switching from my monitor to the tv as primary display, extending the displays, or duplicating the displays. I recently took the computer into my living room and hooked it up to the 37" HDTV via component cable.

The cable is high quality; well insulated, 24K gold plated ends. I had to use my monitor as the primary display in order to set up the component connection as composite was native to my computer. Once the tv was setup and working, I changed it to the primary display and removed the monitor. I only connect my computer to the tv when I am using it, and have had no problems. The other day, I took it back to my desk and used my monitor. Ever since, even with the monitor connected, my computer will not detect the tv at all and therefore won't display on the tv. Connections are good, no settings on the computer were changed other than it automatically reverting back to the monitor as primary display. Since the problem, I have updated to the newest Nvidia drivers with no change. I turn on the tv and set the correct input before booting my computer; nothing. The sound works so it is
undoubtedly on the right input. What could be the problem? I have searched google and found many similar problems unsolved. Some of the new cards do not support the s-video to component adapter, but I have been using it with no problem. My card has 2 DVI and 1 9-pin s-video outputs. Someone on a forum said that nVidia suggested everything I have already tried (update drivers, turn on tv to correct input before boot) and the individual's problem was not solved and nVidia offered no more suggestions. I am stuck on this. Any help is appreciated.

I've been searching continuously. This seems to be a common Windows 7 problem, but I can't find a solution. People said that if it starts showing you have an HDTV when you don't, there is a pin problem inside the video card's s-video port, but mine shows nothing. I tried what people said and tried pushing the adapter in different directions and holding it with no results which leads me to believe the video card output is not the problem. Still trying to find more.

I checked a few things. The tv is not detected and has no display on component or composite input BUT...it works on s-video which means no HD and res is way too low for this tv. People are saying the s-video ports on these cards have a tendency to go bad. What makes no sense is that I am using the 9-pin s-video port with the adapter that has component and 4-pin s-video. So either the 5 pins on the video card related to the component video are out or that part of my adapter went out or the software is not allowing that to work.

Does DVI to HDMI work?
Is the video card also being used as a sound card?

The 8800GTs does not have HDMI on it and he does not use HDMI on the TV. He prefers component input. And no he is not using it as a sound card. He has an actual RCA-Phono Jack cable for that.

Sorry, meant DVI adapter to HDMI...if he has an adapter and HDMI cable, try that to see if it works... Stuff can go wrong when a digital signal is converted to analog and then back to digital again. It's just one less unnecessary step that could be causing the problem.

Another thought, in CCC there is a "Force TV Detect", have your cousin check Nview for a similar setting.

If the card still doesn't see the TV then something could be wrong with the TV input...try different jacks. And also test a DVD/Bluray player or other gear with the component input the 8800 was connected to.

I moved this to tech talk to see if I could get some more ideas on what to try to fix this for him.

Sounds like a driver issue. First, I would try to return to a previous driver in Device Manager. Often, Microsoft automatic updates can be installed a new class driver does not work with all chip sets. Secondly, it does not work, install the latest drivers for the website of the hardware manufacturer for you.
