Question about Westinghouse Electric L1916HW 19" Monitor
My monitor and CPU went into sleep mode and the monitor will not stay on now. I unplugged it turned it on and goes off after a second or two. No matter what I do it will not stay on for more than a second or two. The "W" at the bottom of the monitor flashes like it does when the CPU or monitor is in sleep mode. Is there a fix for this?
When the computer enter the sleep mode, it is possible that the computer remove the check mark from this output activation.
When you have multiple ouptut like a internal LCD and output on a monitor, when going into sleep then waked up, laptop reactivate the internal LCD without reactivated the secondary monitor.
you could need to go in desktop property and reactivate the secondary monitor with the check mark listed : Activate.
If you only have one monitor but still a dual output card or two separate video card same thing can happend. try to connect the monitor on the second VGA or HDMI output and see if the video goes there.
then reactivate your secondary output and make it principal.
Does also happend when your computer is connected to a UPS power and your monitor is directly on the sector. (laptop issu also)
if a brief power outage arrive then the monitor shut down (no power) and the computer continu, as there is no monitor on the output any more Windows will automatically deactivate this monitor. when power goes back, this output is no longuer providing video. I suggest putting the monitor on a UPS as well.

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 monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/

Your computer monitor or laptop screen will enter sleep mode after your computer remains idle for a set period of time. You can disable sleep mode if you prefer the screen to remain illuminated. You merely need to change a setting in the Windows Power Management properties box.
Difficulty: Moderately Easy Instructions
Click "Start" and "Control Panel".
Click "System and Security" and "Power Options". This will bring up a new dialog box.
Click the menus to the right of "Turn off the Display" and set them both to "Never". This will disable sleep mode.
