Weird colors after testing tv out

Hello,
I have an e-gforce 5700 ultra on an xp machine and i recently was
testing the TV out with the s-video cable provided with card. Everything
seemed fine so i did a
little adjustments with settings (52.16 drivers) while watching a video
file with WMP 9 and seemed to go ok. I closed the program and took a
coffee break, and when i came back the color was off on my monitor but
not on my tv. I tried restoring all settings that i could find,
especially color correction back to defaults but that did not help. I
updated the drivers to the forceware 53.03 on nvidia site....no change.
My last effort was to disable clone view and unattach the Tv. I still
have funky color
and its not WMP 9 because the color is off on PowerDVD also.

Please help, its very annoying
TIA..jason

BTW.....why does my monitor blink and seem to be strained when accessing
the adapters settings?
