Having problems with your PC Desktops ?

Flat screen is going out

\015 Envision 7400e just started blanking out. Upon windows opening, right clicking on graphic options and switching from lap top to monitor, the monitor lights up for approx. 2 to 3 sec. then blacks out.\015\012Through process of deduction, I replaced vidieo cord and no solution. Then I hooked new cale to another lap top, thnking video card in my laptop could be going out. Again, no solution.\015\012Obviously, it is the montior. So any ideas what might be happening with monitor?\015\012Thanks for any ideas.\015

Answers :

Replace the VGA or HDMI (whichever you're using) Cable, and the Power Cable (one of the two can cause this problem, or even worse, fry it!)
\015\012Then,...... try connecting the monitor (with new video and power cables to another pc that you know for a fact is working correctly... the problem could be your power supply, motherboard, etc..
\015\012If that doesn't work.....Return The Monitor if you can..........cuz if the above doesnt fix your problem, ........then you'll know the monitor is bad......but don't assume that til you try my solution k!
