If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

The flashing power button is an indication that the power supply has failed. There are parts called capacitors that filter the output power and when they short out the power supply can't start up correctly os it tried over and over, this make the power light flash each time it tries to start up. The monitor is easy to repair if you can do a little soldering. Here is a link to a repair guide that will show you how to dis-assemble the unit and what to look for and replace to get it back going again. Te guide also has videos showing the steps.

Hello Dfrank,

The 920N units use the same power supply board that the 710T uses and it was a known issue with bad capacitors that fail. When they fail it can cause the issues that you are having - Either slow to show a picture, wavy display or no power and flashing power light. The boards can be repaired if you can do a little soldering, the parts are cheap. We have a step by step repair guide posted on our tech support web site at: http://www.ccl-la.com/blog/index.php/repairing-the-samsung-syncmaster-710t/ This is an easy repair for a very nice monitor, well worth repairing it.

I hope this helps, if so please rate my solution.

A fast blinking power light is an indication that the power supply is in a shorted condition. Parts called capacitors that filter the output power on the power supply board can fail and the power supply will short out causing the fast blinking power light. If you can solder then you can repair the monitor. Here is a link to a repair guide that has pictures and videos showing how to dis-assemble the unit and what to look for and replace to do the repair.

Hi I have a samsung syncMaster 920N The screen has suddenly gone blank - the power light is showing. I have a second identical monitor and have swapped cables but no difference Is it a repairable fault?...


This happened to me a few months back. I removed all cables and left it for 2 days. Switched back on on it worked fine. That is until yesterday when half the screen went black. I found that my driver was out of date. I have undated the driver but have decided to leave it off and unplugged for another day.
You could try this. You say you have another monitor, i would suggest using it for a few days and the try the old one again.

Samsung products does not require u to produce a bill during warranty, ur product info will be registered in the database of the customer care center. So you can go in and get ur claim with the warranty. And the about the green lines, it could be that something is wrong with your graphics adapter.
