  1. do you have a second monitor to check your vid output, or a second computer to check this monitor with, even if it's a laptop( providing your monitor has VGA input)

    It looks like your monitor goes on power saving mode because there is no video signal coming in.
    First, check if the cable is properly connected to the video output port of the PC.
    If it is, please tell us whether the monitor display anything before or you have a new PC build.

    Do you mean you connect both your monitor in the same pc through different display port hoping to get dual display? If yes, then you have to set your display properties to "extended desktop".

    yes very true...i just thought it was maybe a minor repairable thing.. i dont think it is too old though lol
  10. the newer LCD's are pretty good, those about 2 years old and older, some mfg's cut corners on cheap intenal controller, and quality is questionable, I am in China, I can take it to a electronics repair place and get stuff fixed that could never have been done in the States
  11. Sounds like the backlight or inverter are going. If you shine a bright light on the screen after it goes out, do you see a faint image of the screen? If so it's the backlight. do a search for backlight problem for more info.

    I shone the light on the screen and its just blank...If i put the power switch on the monitor off, then on it does not show the picture quickly as if i had to unplug it and then plug it back in.. :cry:
  13. Take it to your local tv shop and have it fixed by a pro.
