Will not recover from Power Monitor turn off

Use to have the Windows XP Power Monitor set to turn off the monitor after 5 minutes of inactivity. When the mouse or keyboard use was sensed it would turn back on. This no longer works. It still turns off but won't turn on unless I reboot the computer. I can still get almost the same effect by using screensaver set to a blank screen. Screensaver still works. I've tried the monitor on a couple different computers also using different cables, so I know it's the monitor causing the problem.

SOURCE: Hitachi Monitor turns on for a sec then turns off.

Since you have already indentify that the problem is with the monitor, next thing to do is to open it up, but if you are going to DIY repair, then you should read below and look at the pictures so you will know what to look for inside.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Screensaver will not turn on after inactivity

This is an adjustment made in the control panel under I believe Display. From there you will have an option for Screen Saver. It should all be in there.

Hp w2207 monitor randomly goes to sleep randomly, using windows xp

First make sure all the cables are securely plugged in. By randomly, do you mean a set amount of time of inactivity? Try this. If that doesn't work, it may be time to replace your graphics card (or buy one) or time to buy a new monitor.
Good luck.

My monitor goes to sleep and I would like it to stop. I can't figure out how to accimplish this. Karen

That's probably a Windows setting. For Windows XP:
1. Right-click the desktop.
2. select properties
3. go to the screen saver tab in the window that opened
4. check wether the screen saver is set to "None" If not, do so.
5. Click the "Power" button
6. In the window that opened, set Turn off monitor to never.
7. You're done!

For Vista and Windows Seven:
1. Right-click the desktop,
2. In the windos that opened, click personalize,
3. Click screen saver (bottom right)
4. In the window that opened, set the screen saver to "None"
5. Click "Change power settings"
6. In the window that opened, click "Choose when to turn off the display"
7 Set "Turn of the display" to Never.
You're done!

My monitor keeps turning off after 5 seconds of it being on.

Assuming you are using Windows XP or Vista... Check the power management settings. (Start...Control Panel...Power). You can set whatever you want the time interval to be when the monitor goes into energy save mode or off.

Dell SE198WFP 19" LCD won't come out of standby

I went into the BIOS (with F2 during restart) and changed a value -- IIRC it was called something like "power management scheme" -- from the default S3 to the other choice, S1. Now the old Dell XP Dimension 2350 will go into and out of Standby correctly and the new SE198WFP 19" LCD will too.

My monitor goes to sleep all the time it is very frustrating

Go into Control Panel, then to Power Options.
In XP, you see a selection for Turn Off Monitor. Adjust that setting as desired.
In Vista, you'll see Choose when to turn off display on the left side. Choose that option and select the desired time setting to turn the display off.

The moniter light will blink on and off randomly and the screen also turns on and off with the light. What can I do to fix this?

This is most likely due to power management settings for the monitor.

To address these settings follow the procedure below for your version of Windows.

To establish which version of Windows you have:
Press and hold the Windows Logo Key on your Keyboard + Press Pause Break Key and release.

To adjust power management settings in XP:
Click Start > Control Panel > Power Options > Adjust the drop-down menu for your Monitor.

To adjust power management settings for Vista:
Click Start > Control Panel > Classic View > Power Options > Click "Change Plan Settings under your current plan (the plan with a filled bullet) > Click "Advanced Settings" > Click Display > Click "Turn off display after"
Select 0 for none or choose the duration of inactivity to wait before Windows blanks your screen.

Monitor shuts off after inactivity

Hi maggieis,

I wouldn't worry about your monitor powering off after 30 min. It's just responding to the power management settings that are configured from within Windows.

These settings can be changed so that your monitor always stays on (if you want) but the current setting is set to help save energy by turning off the monitor when no one is using the computer.

So, no worries...that's just normal Windows behavior.

Hope that helps,
