Black screen power goes out--black screen --in power save mode

The monitor has failed, it is almost always cheaper to replace it than fix it.

alastairhaig, Is unit 4 years old? Could be problem with units switch-mode-power-supply if same thing occurs when connected to fully functioning different pc that has all screen saver and power save features disabled. After screen goes "black" do you still see the WIN-desktop screen and icon's if you hold a bright flashlight at different angles about 1 inch from the screen? SEE = power supply in "partial shutdown" mode. NO SEE = smps in "full shutdown" mode. Do some reading in my fixya profile about "black screen of death" repairs. also read FIXYA profiles of "budmrtn" "buddymc" and other fine profiles of technicians here on fixya. You will truly be amazed when you visit YOUTUBE for video clips of owners/technicians who save their cold cathode fluorescent lamp, back-lit lcd monitors from the "trash-heap"!!! After you do your research please return here and rate this response and possibly do additional comment. 12fixlouie

Open Control Panel.
Open Power.
Change the number of minutes before the screen goes into "power-saving" mode.

its just ur monitor setting or the setting in ur pc for stand by mode or power saver mode.

if u still could not figure it out pl say me which system u using(platform)

Hi, the Power Saving Mode, turns the screen off to conserve energy. On the remote, press Menu, and scan to Power Saving Mode. You can change the amount of time, when the Screen turn-off, the TV shut-off etc. You can set the time to (5 min) to, (never, turn-off). This should help with your problem. Thanks paul7of9

Hi erin mckinle,
That is probably it's, uh, analog power saving mode. When the screen goes black and the power button flashes, make some mouse gestures or hit some keys that would not affect anything (try spacebar). That should bring up the screen. If you think it goes into power saving mode too fast, go to Control Panel --> Power Options, and change the values. Hope this helps.

ya i bet it is, this is a bad virus from file sharing programs.
use virus removal tools,
or restore to factory with restore disc/ wipe hard drive and reinstall OS

right click on your desktop.go to properties.in properties go to the screen saver tab.click on the screen saver tab.under the screen saver tab you will a tab called power.click on power.change you monitor settings there.let me know if it works

1.Check the VGA Cable
2.IF it is correct CHECK RAM and clean the RAM twice


if it helps

RATE ME

inside the power pack is a pulse IC chip they fail and cause all kinds of havoc also caps can cause issues unaccounted for, I would start at replacement of the IC about 2 dollars on E bay, and replace any bad capacitors you can see, they look domed or are leaking color from the top creases. after that get back with me and we can either proceed or you can rate me fixya, have a great weekend
