On some occasions the monitor needs to have the power cord unplugged and restarted, durring these times the power buton will not work. Any suggestions appreciated. BTW the problem is unrealted to the pc it is attached to so it is not a resolution of freq issue.

    More information please. Where is the command section? Are you suggesting a loose memory chip or bad one?

It sounds like a faulty power supply to me or a leaking capacitor. If it only happens with sleep I would suggest turning off the power saver in you operating systems power settings and just using the power button until the unit ceases to function.

Fixing it would involve taking it apart and looking for burns or bulging capacitors. You will need to replace them with new ones. You will also have to see what caused it.

Good luck

My Dell monitor goes to sleep right after windows xp starts to load and it won't come on after that. my computer is still running but the monitor is a sleep. I have hit f8 and f12 with nothing happening....


Go into safe mode
Under settings, control panel, power options set "turn off monitor to never
reboot

I think this is not a sleep problem but the incorrect monitor settings were set. This will cause the screen to go black when the OS comes up. Boot in safe mode and change the display settings
to 640x480
OR
in safe mode, delete your monitor. When you reboot it will load a default monitor and you should be OK

The blue light around the power button is doing a slow blink, the pc is up and there is no picture on the monitor.


The computer is "sleeping", in power-saving mode.
Touch any key, or wiggle the mouse, to awaken it.

Or, touch the on/off button, to awaken it.

1 Answer

When I awaken my computer by moving the mouse the LCD light on the monitor keeps blinking off and on for over a minute before the screen comes on.


Delays are common for systems coming out of sleep mode and it isn't only the system box that must wake up but the monitor also samples its input to determine if a signal is present before it comes out of a power saving mode.
If the monitor is a CRT unit, the jug needs some time for the heater to warm up and emit electrons again, if an LCD, the fluorescent backlight and its circuit can have delays too.

Admitted, a minute seems a bit long but may just be the combined characteristics of your system and monitor.
It still beats booting up from scratch.
