What causes my Samsung 920NW LCD monitor to go dark after a few seconds? I am running windows vista home premium. Thanks


If the power indicator remains on, the problem lies in the inverter board that powers the back lights. The cause is usually bad capacitors that sometimes bulge showing they are open. the board needs to be replaced or an attempt made to repair the old one.

Hi I Got a Samsung SyncMaster 920NW the display


If you are saying that it powers off in a few seconds you most probably have a bad (internal) power supply.

Flashing power button on Samsung SyncMaster 920NW


Yes, More than likely the problem with the unit is blown capacitors on the power supply board, the flashing power light is a good indicator of this type of failure. Here is a link to a repair guide with pictures and videos showing how to open the unit and what to look for and replace to get it back going again.

Most common cause of the failed monitors are bad caps in the power supply, if it is about two years old, I would open it up and look for bad caps first, then look for any burnt parts, post back so we can guide you further, see failed SAMSUNG monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Samsung SyncMaster 920nw suddenly went black now squeaks/flickers


The 920nw did have a 3 year warranty on the unit but they will be out of warranty now. The flickering power light is an indication of a failure in the power supply board. When the board fails it can't start up correctly and the power shuts down over and over so you get the blinking light and no display. This is a very common failure point on all LCD monitors after a few years of use. There are parts called capacitors on the power supply board and they filter the output power. When they fail the power is not properly regulated and the power supply shuts down and tried to restart so you get the flashing. Here is a link to a repair guide that will show you how to dis-assemble the unit and then what to look for and replace to get it back up and running again.
