SOURCE: Going to Sleep

Due to the power surge, it is highly possible that the monitor was given a boot by your computer on it's way out.

This will short out a very small transistor inside the monitor on the video board and in turn, then monitor cannot see that there is a signal so goes to sleep.

If you get brave enough to venture inside the screen, then check near the cable input. The transistors are only around 3mm and have 3 legs (two one side and one in the middle on the other).

If you find anything like that burnt (get a magnifying glass) then replacing the board is the easiest option. Just don't be tempted to wipe the board before you look at everything very closely, you may wipe away the tiny bit of evidence you are looking for.

Hope it helps =)

SOURCE: monitor goes to sleep and never wakes up

I have called HP Technical Support 6 times about this issue and have logged at least 14 hours into the issue. The things they have done are turn all sleep settings in the "Power Options" in the control panel to "never". The problem persisted. Today, they sent my problem to the complaints department, so maybe they will have the authority to do something for my 5 week old setup.

For me, the monitor was in the "other devices" part on the device manager (go to start menu and type device, and the device manager will show up). I went to HP's website to the support and drivers spot and found a patch for the My Display program. This will allow you to uninstall your monitor, just right click the monitor under "other devices" and click uninstall. After you uninstall, restart and your computer will recognize the and put it under "monitors" in the device manager with the updated drivers. After I did this, the monitor hasn't gone to sleep.

SOURCE: monitor willnot come out of sleep mode

turn off everything and restart computer in safe mode,do this by holding down f8 as you reboot,then go in your setting and remove time limit on sleep mode.

Hi publicworker,

I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.

How to do that:

• right mouse click on the desktop
• select graphic options
• output to
• extended desktop

SOURCE: Screen shows message "no input signal" and monitor goes to sleep.

monitor show "no input singnal" error masage when not gating any type of video singnal ,
so if u realy check your monitor wires for correctty plugged in .
then:-

Two possibilities:

either the video/mainboard of the monitor is defective; or
the video card/ CPU is the faulty.

A way to verify is to try the PC with another monitor or to try the monitor in another PC.

thanks
