Monitor goes to white at cpu shutdown

I need help on finding out why my monitor goes to white. I shut down my windows XP system and the monitor started to go to a white screen, and stays that way until I unplug the monitor or restart the computer. Turning the monitor off with the monitors on/off does not work, it stays white. It is so bright at night I have to turn off the surge strip to cut the power to the monitor, so I can sleep. Please help. Thank you in advance, Kevin

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. Your monitor looks like it may be in need of repair, contact info: PTI Technologies Inc. 7372 Doig Dr. Garden Grove, Ca 92841 Phone: 714-799-3899 Fax: 714-379-6290 Hours: Mon - Fri 8:00am to 6:00pm PST

    Kimi i think you're probably not getting it. she meant that when she turns off the monitor the screen instead of turn black it turns white. i know it because i'm having the same problem. in other words, we're not talking about comsumption of energy. we're talking about the color of the screen.

    Agree, having the same problem that just started a week ago on my Dell monitor. It is the second monitor on my desktop system, and have never had the problem before. The computer and primary monitor shut down normally, but now the Dell screen turns a bright white. Of most concern, is that I cannot turn it off with the power switch, and have to unplug it each time I shutdown the computer. Other than that, it works normally.

I am having the same issue, but it is with a lenovo netbook. The original screen was cracked so I replaced it. It works fine if the computer is turned on, but as soon as I shut it down the screen turns white and will stay there unless I unplug it and take out the battery or it runs out of juice. Any and all help will be appreciated. Thanks

Out of range no display

Try pressing F8 when starting the PC, but BEFORE Windows starts loading. In the menu, select Safe Mode. Windows now startd with a very low resolution. You can right0click your desktop, select properties, then the Settings tab, and drag the reslution slider all the way to the left in Windows XP, or for Vista and 7, rightclick the desktop, sleect the lowest option, go to screen settings, and drag the slider all the way to the left.

After that, click OK, then restart your PC. Now you can try to increase the resolution step by step, and if it goes wrong start in safe mode and set it back a step. That way you will achieve the highest possible resolutioon (and better image quality)

I hope this helps,

Hi Brandy19960,

Thanks for the posting in FIXYA.

Please do the following steps:

Step – 1

Right-click on My Computer, open Properties, click the Advanced tab. Under “Startup & Recovery,” click Settings. Under “System Failure,” Uncheck the box in front of “Automatically restart.”

Step - 2

To change the setting, click Start --> Run--> type GPEDIT.MSC, click OK.

Drill down to Computer Configuration | Windows Settings | Security Settings | Local Policies | Security Options.

In the right pane, find “Shutdown: Clear Virtual Memory Pagefile.”

NOTE: Since someone actually has to have set this policy, the problem will be pretty rare, but is worth mentioning. However, Forum participant “roadrunner” reported that the personal security app Privacy Eraser automatically enables “Clear virtual memory pagefile,” and, therefore, may be the cause of a slow shutdown.

Step - 3

When Windows XP won’t powerdown automatically, the APM/NT Legacy Power Node may not be enabled. To enable this, right-click on the My Computer icon, click Properties | Hardware | Device Manager | View. Check the box labeled “Show Hidden Devices.” If it’s available on your computer, there will be a red X on the APM/NT Legacy Node. Try enabling it and see if this resolves the powerdown problem (Tip from Terri Stratton). Or, to check the other side of the APM/ACPI coin, open the Power Options applet in Control Panel. If there is an APM tab, make sure the “Enable Advanced Power Management Support” box is checked.

Step - 4

Try a Shutdown shortcut -

For a shortcut to RESTART Windows XP:
SHUTDOWN -r -t 01

For a shortcut to SHUT DOWN Windows XP:
SHUTDOWN -s -t 01

Step 5

WORK-AROUND: Disable power management for your USB hub: Open Device Manager (click Start, click Run, type DEVMGMT.MSC, click OK). Double-click to expand Universal Serial Bus Controllers. Double-click USB Root Hub. Click Power Management. Uncheck the box “Allow the computer to turn off this device to save power.” OK your way out

Step – 6
Click on the Start button.
Select Run from the menu.
In the run dialog box type “msconfig”.
Click OK.

Once in the msconfig utility select the startup tab. In the startup tab you will see several programs listed with a checkbox beside it. If there is a check mark beside the application listed, the application will startup when your computer starts up.

Monitor displays breifly then goes to blank screen

The green power light indicates that the monitor is receiving from the computer correctly. I suspect it is going into high voltage shutdown. There is a safety circuit that monitors the high voltage and shuts the monitor down if it sees anything amiss. So the monitor comes on and then shuts off. High voltage problems are generally not worth trying to repair. Another example of a worthless safety feature. High voltage failures are not dangerous, and adding the safety circuit just kills the unit when it may have some life left or worse, sometimes it is the shutdown circuit itself which fails!
Hope this helps.
