Why is my samsung flat screen monitor black when turn on


Most likely culprit is a defect in the the power module (inside the monitor). Most failures are because of bad electrolytic capacitors.

Do a search using Google and type into the box (the Great Capacitor Plague). Read all about it.

Boot in f 12 windows starts then black screen


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

You either have a hardware problem with your video card. ( may have pop out of socket when you plug in the monitor) or the cable is not allow communication to the monitor. As long as the amber light comes on you know you have power so focud on data cables and hardware.

Boot from safe mode and try a different pixel/color arrangement. Obviously a lower pixel and color setting.
