Just bought a Samsung 24" LCD Widescreen on line from a deal i saw on hotdeals. Plugged it all in, and after trying for a couple of hours i cant get it to do anything. When i power it on, i get a blue light in the bottom corner of the monitor, that lasts for maybe 1/3 of a second, then goes off again. Ive connected pc to it by vga and got nothing. connected 360 to it and got nothing. Changed the power cable and still get the power light on for a fraction of a second then it goes off. Have i got a DOA monitor or am i missing a trick?
