Need help change X.Org [Nvidia+TV]

While this might not be a complete answer, there are a few things I noticed on first sight, which are the post probable reason for having a black-and-white image:
Which country do you live in? You need to set Option "TVStandard" accordingly: "PAL-B" for Germany, "PAL-I" for UK, "NTSC-M" for US. Similarly, Option "SecondMonitorVertRefresh" may be set to "60" only for contries with NTSC, for all PAL countries set this value to "50".
How do you connect your TV to your computer? Using a S-Video cable (small, round, multi-pin)? Then set Option "TVOutFormat" to "SVIDEO" (no dash). Or is it a single Cinch/RCA connector with a center pin (usually yellow, plus audio using a red and a white Cinch connector)? Then set it to "COMPOSITE". If you have three Cinch connectors for RGB (you probably don't), use "COMPONENT". Other possible options here are "HDMI", "DVI", or "VGA".

Uh, what did I type there? The first sentence should read "While this might not be a complete answer, but there are a few things I noticed on first sight, which are the most probably the reason for having a black-and-white image:"

You forgot option "composite' as cruncher suggested.
btw. there should be some tools:
sudo nvidia-settings
or
sudo nvidia-xconfig --composite

Option "TVOutFormat" "COMPOSITE"

No, he said he had S-Video, so "SVIDEO" should be fine.
Unless there are some cable adaptors inbetween. In that case it can't hurt to try the "COMPOSITE" setting as well.
You can also try "PAL-G" instead of "PAL-B", both are used in Sweden, but they have slightly different characteristics.

I uninstalled ubuntu and got windows again, atleast it works and one can get help

Did you even try what Sam suggested? Sheesh...
Well, good luck then with your wide open system, I wish you good luck in not catching a virus. Or trojan. Or spyware. Or system crashes. Or...

I've modified the question to make it easier for other users who look for help on this issue.
