My monitor keeps shutting off at random times

[Ra56925]

As i said monitor shuts off and gos to sleep. I've unpluged the power source doesn't work i've run virus scans doesn't work. I've read online that maybe the power suppley cable to monitor might be overheated or broke somehow. I've cheacked said cable can't find anything that looks damaged

I don't know if i meantion or not but i already did change it to never on the power  didn't work but the computer has stayed on this a problem with the monitor only

>  the computer has stayed on this a problem with the monitor only

Those "power" settings have two elements:

* turn off ONLY the monitor after NN minutes of inactivity,

* turn off (or "sleep") the whole computer after NN minutes of inactivity.

Be sure to adjust both setttings to your personal preferences.

I tried  what you said and it didn't work, is it possible that i have some kind of virus cuase its like someone has control over my monitor. Or could it be the plug?

PS the pc in question i'm using rightnow while the monitor is still on, it could go out at any min.

>  is it possible that i have some kind of virus cause its like someone has control over my monitor.

Yes, it is possible. Disconnect from the Internet, i.e., unplug the Ethernet cable, or "disable" your wireless networking adapter, and see if that makes difference when there is no "rogue" remote-access to your computer.

> Or could it be the plug?

Yes, but at maximum, a 5% chance of it being that.

More likely is a failing power-supply inside the monitor, or a failing video-adapter inside your computer.

Try a different monitor.  If you still have the symptoms, then your monitor is fine, and the problem is "inside" your computer.

Try the monitor on a different computer, to see if the symptoms "move" along with the monitor.

Who do i contact bout replacing the power supply? cause i think its likely that. I have no other monitor that i can use to test your idea that it may be the computer or the moitor. As i've said i'm still under warnnty so if you could give me the number or is their a chat would a great help

Do you have a DVI video-cable, and a DVI-input socket on the back of your TV?

Or, if your TV has a HDMI-input socket, you can buy a video-cable with a DVI connector at one end and an HDMI connector at the other end.  Connect the cable to that #3 port ("DVI-D") and to your TV.

If so, you can use your TV as a temporary replacement for your monitor.

> Who do i contact about replacing the power supply?

Did you purchase the monitor at the same time as the desktop computer?

If not, then the warranty for the computer does not cover any issues for the monitor.

What's the manufacturer & model-number of your monitor?  Size of the screen?

Depending on where you live, there may be a TV/video repair shop near you, with a qualified technician.

He/she probably will charge you $75 to $120 USA to disassemble, trouble-shoot, repair, reassemble, and test.

Add the cost of a replacement power-supply, and it probably will be less expensive to buy a replacement.

Really?

Are you a "hermit", with no friends who can bring their monitor to your location, to do the suggested testing?

Of course, you could buy a new monitor from a store that offers a "one-week-money-back-guarantee", use it to do the testing, and then return it to the store, to get your money back.

Do you have a friend with a laptop computer?  If so, invite them to your home, and connect your monitor to the video-output port of their computer.

What the hell does it have to do with whether i have friends or not? and no i'm not a "hermit" I'm just a pissed off coustmer who bought and extended warranty that doesn't included the monitor!
