After several hours of inactivity, the screen on my SyncMaster 192n goes black, and the only way to turn it back on is by hard re-booting my computer. Sometimes even ctrl-alt-del doesn't work, and I have to turn off the power strip several times to both the monitor and PC. It didn't used to act this way; a simple mouse-swipe used to re-activate it. When the screen does come back on, it usually works fine, unless I walk away for several hours or leave it overnight. As an experiment, I hooked up a different PC that uses a different OS to the monitor, and the same thing happens after several hours. To be sure it's something with the SyncMaster and not my computers, I dragged up my old CRT monitor, and both computers and old CRT monitor operate perfectly fine. I don't have hibernate enabled.

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.

You need to install the Display driver shipped or downloaded from net.

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. Look in our monitor repair section for step by step repair guide for this model it should be the same power supply as the 930. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

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

Take a look at your power saving settings. It sounds like the monitor is set to sleep after 20 or 30 minutes. You may want to change your setting to "never". The settings are under Control Panel - Power management

Two things come to mind...

If the monitor is fitted with moister sensors it will as a safety measure not turn on, this can be due to damp in the room etc.

Second and more probable is the fuse has blown on the circuit board to the monitor. you will unplug power lead open back up and look for a smaller than plug size fuse which is chrome ended and clear glassed. About 3/4 inch long and 1/8th dia.

Ensure these are replaced with a similar graded fuse. Maplins is a safe bet to obtain them. best to take old one in with you.
