The first one is, I have a gateway 19 inch i def monitor made in dec 2007 and used since feb 11 2008 till today. Was on it and the whole screen suddenly went white. tried unplugging it blowing dust out of the plugs etc, still wont work. The second one is, I have a 25 inch lcd envision monitor that works other than the fact that it keeps going off and on off and on and will not stay on. Any help is appreciated. Thank you.
