Ppiaskow, Hi there. 12fixlouie here. If unit covered by SAMSUNG warranty, USE IT!!!! If unit not covered under warranty you will need tech to troublshoot the unit's "switch-mode-power-supply"/"CCFL inverter supply" to determine WHY the SMPS is going into full or partial SHUTDOWN mode!!! Read more of my responses to other owners with same symptom as yours for more options that are open to you. Maybe if you are technicaly inclined, DIY fix will work for you. If not, then don't make a move without doing some research here on FIXYA or for video clips of repairing LCD monitors at YOUTUBE. Cost to fix unit could be anywhere from $8 in parts (DIY) to as much as $60 if you contract out the work. lmistyrel on aim or 12fixlouie on fixya. If this was of some help, then come back to fixya and rate this response.
The problem can be bad power suuply due to bad caps, bad inverter circuits, bad lamps. Look for bad caps first then report back what you see inside so we can guide you further, see example of failed SAMSUNG monitors due to bad caps here: http://s807.photobucket.com/home/budm/allalbums

My Samsung SyncMaster 2463UW no longer auto detects the video input. I normally use it with my MacBook Pro - I turn it on, it detects the digital output and Bob's your uncle.

However, I can actually see the correct output when it switches to ''digital'' mode - it just won't stay there.
