I have a Sony lv-240J and I it turns on all the fans spin but then there is no beep, no boot, no display or anything. After a couple of minutes it just turns off. I connected a display to it and nothing. I tried to use it as a display, it gets read but nothing on the screen. It has been like this for 5 years and I just bought a new motherboard and still no results. I tried a new hard drive with windows on it, still nothing. One ram stick and without ram still nothing.
