Hello, I just need some advice on which way to go from here. I turned my monitor on this morning and the power lite was blinking. Its a Dell E151Pb LCD. After hitting the power button several times, it would shut off. Thinking it was the Video Card, I disconnected the monitor and put it on another computer and it worked fine for a while, then started the same thing again. Then I swiped my son's monitor from his computer and put it on my computer, and it works just fine, so it must be the monitor itself. Could one of the cords gone bad, and if so which one? It has a detachable power cord, but the one going to the VC is wired internally. What does it take to pull it apart and replace the cable?
