Monitor flickers on start up after shut down


Hello,

The symptoms you have are very common on this model. The capacitors in the power supply are beginning to fail and as this happens they can not filter the power correctly and you get the flickering until the unit stabilizes. As time go by the issue will get worse until the unit fully dies. The repair is very easy, you will just need to replace 6 capacitors on the power supply board. Here is a link to additional information on repairing this model.

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.
