Syncmaster 192n blinking amber green - Samsung Syncmaster 192N 19" LCD Monitor

My guess is your video card driver has been altered and is causing the problem. Try rolling back the driver before reinstalling the monitor. Here is a link to the manual for your monitor: http://www.flatmonitors.com/Samsung170N.pdf

From the above manual: "The PowerSaver system operates with a VESA DPMS compliant video card installed in your computer. Use a software utility installed on your computer to set up this feature".

You need to open it up and inspect he caps in the power supply, look for bad caps with bulging tops or seals. See example of failed SAMSUNG monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
Post back what you find so we can guide you further.

Make sure your refresh rate is not set too high. for the 192N it should probably be not much higher than 60Hertz

You need a fluorescent back light and inverter kit. Available on eBay.

make sure that all the cables are connected FULLY.
blinking light means that there is no signal.

Your backlight fluorescent bulb is burned out.

Easy to replace, check eBay.

It could also be because there is a problem with the display controller in the computer. Try to hook up another monitor to this computer and see if it comes up. If it does not work with another monitor, the computer will need servicing. If the display does come up, the Samsung monitor will need service. Good Luck

Unfortunately, you two have two unrelated problems. CB, the monitor isn't asking you for the password, that's the computer itself going into hibernation, which shuts down the video output, hard drive, etc. You need to go into the power-save settings and either disable hibernate, or change the settings to your liking.

The other question about the screen staying on for 5 seconds... thats an inverter board problem.
