There are a couple of things to check. First, turning it on and off may be a chance that it works but may be a bad cable or loose connection to the back of the pc. Make sure the cable is tight with the two screws into the back of the pc, then you can also move the monitor cable around a bit , usually by the end connection points into the pc and back of monitor, if it blanks out , the cable may have a short or slightly broken wire. As well, many people don't check the power cord. If it's the type that plugs into the monitor and is removable, just like the cord on the back of the pc, make sure it's tight into the monitor as it will only connect once in a while and turning it on and off will sometimes get a connection back albeit a loose one. Another thing to check is that you aren't accidentally hitting the power button, this has happened to some, lol. As well, do you have your power settings in windows to shut off the monitor after 15 -20 minutes, standby, or hybernate...to check, right click the desktop, properties, then click on screensaver tab, under it there is a monitor power setting, click "power" look at the first options to see if monitor settings are to shut off after time, if pc goes into standby after a time, then check hybernation and see if enabled as well. If none of these, also make sure you monitor cable isn't laying accross a power cable or where EMI "electro magnetic interference" is causing the monitor to black out. Also if CRT monitor, make sure no high magnetic sources are near it. If not, it's not unlikely the monitor could be going bad, every OEM i've owned , the monitor has gone out in a bit over a year. I now have a nice collection in my garage of the OEM monitor graveyard. If all else fails, check your warranty , usually 3 months to 1 year in home, or if you purchased extended you would be in great shape. That said, it would cost more to get it fixed or close than to buy another. Around my area , noone even works on monitors anymore, simply replace them. Hope this helps a bit.
I am using the monitor that my PC came with, it is a Metro 17". I know it isn't a great one but it is barely a year old. It has just started this thing where it is working just fine, and it goes black. It then takes about 4-6 times turning it on and off to get the screen back. I am running a HP Pavilion 512 MBX2 pentiom 4 processor 200GB hard drive. Windows XP.
Now my question is is this fixable and is it worth it? And how do I do it?
