My 19" flat-screen desktop monitor (Samsung SyncMaster 931BF) has trouble coming on in the mornings when I boot the computer up. I can see the blue "standby" light (at the on/off button in the lower right corner) is on, and the computer itself is on, but the screen remains black.

When I turn the monitor off (for a few seconds) then turn it back on, the screen will come on for a second or two, then go black again. Also, when it comes on (for a second), it's dimmer than usual.

So, I repeat the above sequence 4 or 5 times and finally it stays on and gets to its normal brightness. This morning it took almost 20 times before it stayed on and I'm concerned it's getting worse...

Hello

Looks to me like a graphic card issue. Have you tried another monitor ?
Thanx Ambucias for your reply. No, I don't have another monitor to try. I wonder if there's a method of testing the graphics card to see if it's the culprit?
