How can I operate the Samsung SyncMaster 1200 NF monitor as TV

Download the user manual to your monitor. Refer it. It will have all details about reset. http://www.retrevo.com/support/Samsung-910MP-Monitors-manual/id/278ci759/t/2/

The problem is in one of the inverter transformers, or one of the backlight behind the display is defective.

Hi,
Samsung SyncMaster 2233BW does not support TV / Cable input (RF Connector).
If you wish to connect Cable to the LCD, you have to buy a TV Box and connect Cable with your LCD through TV Box. (Cable TV to TV BOX and from TV BOX to LCD)

Hope it helps! Good Luck! Thanks for using Fixya!

Select which operating system you have and download.

its a snap-type plug-in stand, just hold the stand firmly and pull the monitor equally upward, then it will snap quickly....... but a proffessional reminder! Before mounting your SyncMaster on a wall, be sure to plug the two (2) stand holes located at the buttom of the monitor. My Samsung SyncMaster 2333HD LCD TV was twice intruded by adult-size lizard, both incident resulted to main power board damaged!!!!

It can be very tight sometime.

Set your screen resolution to 1600 x 1200, the native resolution of the screen.

Hi,
Probably there are another available solutions but I think you should respect the monitor native maximun recomended resolution taking into consideration to change (if it is posible) between 16 or 32 bit of deep.
I have the same monitor as you have.
