Why would the Gateway FPD 1730 17 in. Flat Panel LCD Monitor turn on,,then go right back off,,if you leave it unhooked for a few days then it will work for a short time than quit again

kennetharmol, When the monitor lcd screen goes to black condition, you must shine a bright flashlight 1 inch from screen to evaluate if "switch-mode-power-supply"/"CCFL inverter" board is in partial or full shutdown mode!!! Partial = you can see WIN-desktop! Full = not see!! When you stated in your own words "WILL WORK" means 85 to 98 percent chance your working monitor can be repaired on a DIY basis for under $10 in parts. Read my testimonials then through the longer responses in profile and then follow links to other good, but more technicial DIY info on the web. Keep me posted of your progress or lack of !!
