I had the same problem, took it all apart and pushed on the socketed chip, it made a click noise and it works now. I also pushed on everything including the variable resistors. First time it's worked since it quit working!!

You should have received two cables with the monitor. One is for VGA and plugs into you video card or computer board . The second one is for DVI digidal video and if you have that cable it plugs into the square connector. Then if you look into your monitor manual or quick setup sheet it will tell you how to connect and set the monitor to either VGA or Digital. I'm sure that is what has to be set. Don't hook up both cables to the monitor and computer. Only use the one. Digital gives you a better picture if your computer has that function. Hope this is helpful. Bud

Typically this happens when the resolution of the display is out of range of the monitor. Normally this is when the resolution is too high. Have you changed the resolution settings? Also, not to be crass, but if there a video card in the system, be sure that you are connected to the correct VGA connector. With an extra card in the system, the onboard VGA connector is not used.

Keep us posted,

1. please check by pressing num lock or caps lock key to verify that your machine is booting up, if yes then check the cable and if after changing the display cable it doesnt show up anything, it means you have a faulty unit

2. if numlock/caps lock key doesnt work, then your machine is not booting up, please check for loose ram etc.

had the same issue, called up customer care of samsung and they suggested me to change the cable to D-15 10 series. I was getting the comp o/p on TV but with the "Check Signal Cable" messg with the old VGA cable where some pin is not grounded used for computer to monitor connectivity.
