Question about Sylvania CL972B (Black) 19 in. Flat Panel LCD Monitor
My monitor turns off whenever I leave it idle for more than 2 or 3 minutes. But it will not turn back on when I use the keyboard or move the mouse. It will only sometimes turn back on when I either hardboot the computer or unplug the computer entirely.
What's wrong? How can I fix it?
It is probable that the ROM system, called BIOS (Basic Input/Output System), is set to not wake your computer by moving the mouse or pressing a key on the keyboard.
I do not know which BIOS your computer is running so I can only give a general answer.
When your machine is starting up, look for a message that says "Press F2 to enter BIOS" or something like that. Your machine may have a different F key assigned to enter BIOS.
There should be a setting in there that allows you to change the values for waking the monitor. It should say something like "Use keyboard and Mouse to wake up computer", it won't say those exact words, but something like that. If the value is set to disabled, then enable it. Then save your changes and exit (Usually by pressing F10)
Be careful when in BIOS. Changing settings you do not understand can make your computer behave erratically or stop functioning altogether.

The problem is in the "soft switch" technology: On some of Sylvania's newer monitors they have incorporated what is called "soft switch" technology. This allows your ATX power supplied computer to turn your monitor on and off using it?s software controls. Therefore, your monitor?s light will always stay on blinking even when your computer is off. The monitor in normal operation consumes about 80W of power; in the "OFF" state it will be reduced below 8W. The "OFF" mode of the monitor can be controlled by the PC input signal or by pushing the soft-power button to disable the PC signal control for manually turning off the monitor screen. Thus, when the monitor is in soft-power "OFF" mode it still consumes a very small amount of power. For the purpose of making it noticeable to the user that the monitor is in soft-power "OFF" mode, we designed the power indicator to provide for a slow blinking signal (every 2 seconds). If you need to totally turn off the power, then the power cord would have to be unplugged. The same is true of the PC itself, but the PC does not provide for notification while in "OFF" mode.

SOURCE: When I power off my LCD Monitor
If this has happened to two monitors on the same computer, then i dont think the problem is with monitors, i think the problem is with the graphics on the computer, i suggest uninstalling the driver for the graphics card in device manager and then restart the pc to see if that makes any difference. The divice manager in in the properties of my computer icon, just right click and choose properties, then device manager.
