HDMI output - Green Screen

Question

Hi,
i've connected my arch linux box to my TV with HDMI
sometime the screen became green and not black as it should be, it happen in tty but also in gnome.
the only way I have to bring back the coloro is to reboot, but if I leave it alone for a while, the tv goes in "screen saver mode", when I resume it, what is supposed to be black is green, and waht is supposed to be white is pink.
do you know how I can fix this?
thanks
