More about blank screen start
  1. could you connect another monitor to you system for the graphic output test this one could be defective
  2. I don't have another monitor. I'm pretty sure the one I have works. It just seems like it's not detceted at boot. I think...
  3. do you have another cable or video card your try so we could made shure your monitor is ok ,monitor receive video signal but if it wont start when you put power on it could be defective
  4. it does start, it has a switch that is always in the on position. this switch turns blue when it has power and active. the switch turns yellow when it has power but screen blanker has reached the blanking time . when i turn on the power strip the cpu and monitor are connected to, giving both power, the switch turns blue then yellow. like it's idle.
    i would try your suggestion but don't have the parts.

    if it turn blue then it work the yellow light means it does not receive video signal from the graphic card on the computer try to check the video card or borrow one fro m a friend even if it is a old one
  6. good idea, but why does the monitor eventualy recive a signal from the graphics card? i'm looking at it now and all day.
