Having problems with your Samsung 943N LCD Monitor ?

My Samsung 943N LCD monitor will work for 1 second and then goes black. When I choose the extended desktop option, for example, it will flash my desktop on the monitor for a second and then go black. I have 2 cords that I have tried this with and it happens with both...and I have 2 computers I have tried it with and it hasn't worked with either...so it definitely appears to be a monitor issue. Because it works for a second I am really confused with what it could be (it's not the graphic card obv

Becky_bitz, Do this first! It is only a "rude&crude" evaluation of the state of the monitor's "switch-mode-power-supply" Reconnect 943N to a fully booted KNOWN GOOD pc that has WIN-desktop showing. Then and only then, turn on the 943N and note what happens. After the screen goes BLACK, shine a bright flashlight at the lower left corner to try and see if the WIN-START button can be seen or other desktop icons are being displayed even though the LCD panel appears to be black! If you see a very faint image the SMPS is only in partial SHUTDOWN and is still powering the VGA/LCD interface board to display the images. If you see NOTHING, then SMPS is in full SHUTDOWN mode. In either case, your monitor's SMPS is trying to save itself from a catastrophic, nonrecoverable failure.(smoke,fire) Becky, fear not the those last two words. In fact your words "work for 1 second" means that the 943N is a good candidate for repair even if to keep as a working spare! To help in your decision making process you should pay a 30 minute visit to YOUTUBE and search out and view some of the longer video clips of "LCD monitor disassembly" , "LCD monitor repair" and also visit some websites you find here on fixya. www.ccl-la.com/badcaps.htm , www.lcdparts.net , www.badcaps.net are just a few that will point out what is causing your "cold-cahtode-fluorescent-lamps" to fail after 1 second. If you still need help then do a comment to your original post and I will try to help you. lmistyrel @ aim.cm or 12fix louie on fixya. If this was of some help please rate on fixya.
