From the description one of the inverter transformers have failed, located on the power supply/inverter board.

Somewhere in the settings you can tell it to "scan" - it does, and finds all of the channels that are coming in (or trying to come in). Good luck.

Hi, Same problem as mine! Are u suing the original Samsung CX511n cable? If not, video will not appear! Buy the original cable!

There are no drivers on the Samsung site that I could find.

That said, you don't need drivers for your monitor. If your monitor isn't displaying anything with your new computer, try turning your computer completely off, make sure your monitor is turned on and plugged in to the computer, then turning the computer back on. Windows should automatically detect what resolutions the monitor supports and your monitor should start working.

Around here, it's impossible to buy a "new" 15-inch LCD monitor,
because "used" ones sell for about $30 US.
In comparison, a qualified TV/video technician will charge $60/hour to trouble-shoot.
So, rather than spending money to try to repair it, spend an equal amount of money, and buy a replacement monitor.

you probaly need you power pcb repaired or the invertor replaced. sometimes the backlights burn out.

samabbott, Toni, The very first thing to check is Samsung warranty.. If not valid you will need to check and see if Samsung has a cash+old unit swapout program for refurbished same model??? Will this 512N do same thing if connected to different pc? If so, then I would suspect the unit's power supply. Whenever strange or weird stuff starts to randomly take place with an LCD display, I would first check the "switch-mode-power-supply"! Have you tested the pc with different Known Good lcd unit? Try the above stuff and report back with a new comment. 12fixlouie
