My power light just blinks on my monitor with nothing on the screen. What could be wrong?

Question

could the CRT tube be out??

Answer 1

try pushing the monitor plug in at the back of your computer, if that don't work,

open up the computer case and gently press down on the video card (that is if you have a video card in the computer), and it is not integrated into the mother board,

is your computer booting up?
