On my laptop, every time I flip the monitor down and back up, the screen turns black. What should I do?

Okay, there are different possibilities as causes for this problem. It could be your monitor as mentioned above, It could also be that your motherboard is on its way out. I have this happen on my laptop twice in the past four months. If the cooling system on the motherr board goes out, it will shut off  or stop working if it starts to overrheat, the only problem is that by the time it shuts off, some damage has already been done to the mothe board. It could also be an unidentiified virus that AVG doesn't have a definition for yet and even if it does use heuristic technology to scan for unknown viruses, there are some that are elusive enough to be undetected even with a definition. and even if the virus scannerr does eventually pick it up, the virus will have already done more than enough damage, this happened on our computer. or it could be a virus that prevents anti-virus software from updatin, this has also happened on our computer.

If it is still under warranty - call the company.  If not, is it a CRT or LCD monitor?  Every now and then, just like anything else - you can get a dud and all you can do is replace it.  Good Luck!

i know this will be a pain, but try it on another computer. this way we can tell if it's the monitor or the video card. I have a feeling it's the monitor. While you have the cable disconnected, check the pins. It's real easy to bend one.

If you have it set to the highest level of brightness on the monitor and it still isn't bright enough you likely have a failing monitor. I have had the same problem before but there wasn't anything I could do. You can also see if there is a reset option but I don't think it will help.

try changing your refresh rate to stop that, sounds like you have the monitor plugged into a power strip so its not saving the settings

try unplugging power ,and from video board,\nre-attach and reinstalling drivers,\n\ncheck:\n display properties/ settings/monitor / monitor settings / MHZ \nset at 60 or 70 etc. ...\n\ncheck monitor buttons brightness/contrast , default settings,

it shouldn't do that, try to unplug the monitor from the pc and then plug it back

If the refresh rate solution mentioned earlier doesn't work, check your screen's user manual and see if it has its own, built-in power saving feature. \n\nLCD screens are very suceptible to burn-in, so some models will turn themselves off if they don't sense enough change in the picture in a given time frame. You'd turn this feature off through the Menu button on your monitor, if it has it.\n\nThat said, your Windows power settings may also be set to turn your monitor off after a period of inactivity; this would happen even if the PC is performing some task, such as playing music, downloading, etc.; anything that doesn't involve input from the mouse-keyboard.\n\nYou can test this by striking any key on your keyboard when your screen is blank and the computer is running. If the screen comes back on, it's Windows turning the monitor off.\n\nTo stop that, go to Start --> Control Panel and choose Power Options. Under Turn Off Monitor, choose Never.\n\nAgain, be careful; LCD monitors do burn in, so you don't want to leave the same image up all the time or you will get "ghost" images.

Go to your desktop, right click and hit properties, Go to the screen saver tab and choose monitor power. Change options to keep the HDD on and no standby or hibernation. See if that "cures" the problem.

Ok.. if it is a work computer, then you really need not worry. Contact your IT department and tell them your monitor is giving you trouble. They'll fix it for you.\n\nIt could also be that there is no problem with the monitor. \nProbably some magnetic disturbances around the monitor led it to be distorted.\n\nWhat you can do is, leave the monitor off. unplug it. for about 15 - 20 minutes. until cools down completely. \nThen turn it on. \nThen "Degauss" it\n\nIf you dont know how to degauss, then read further. \nGo through the "Menu settings" of the monitor. \n\neach monitor has different way to access the menu settings, so i dont know how to do it on yours because you did not mention any specs of your monitor.\n\nbrowse through the settings to find for something called "Degauss" and select it.\n\nThe monitor may flickr for a second and come back on .. .. \nIf that does not help.. then your monitor is DEAD. \n\nhope that helps.

i had that problem with one of my LCD screens i would check the cable between the computer and the screen(the cable that has a blue head on both ends) see if anything is stuck inside the area that plugs into the back of the computer and make sure that its pushed in all the way.(this was suggested to me by a friend)\n\nedit---\n\nYeah, you are experiencing a blue shift which happens to some LCD monitors after extended use. The previous poster is correct the red is going out in it causing it to look more blue. Your monitor is getting ready to fail and unless you have another one sitting around to use check out any number of Viewsonics (at around $200) from Newegg, http://www.newegg.com/product/productlis...\n\nBefore you ask, no, there is no way to fix this problem.\n\nI quote Conradj213 (I asked this question again and this was one of the answere I got, I believe it to be true)

I would try to hook it up to an external monitor and see if it works normally. If it does, I'd guess the backlight is out, which is located at the bottom of the LCD panel. Not many repair shops know how to repair such a thing. Usually when the inverter goes out, you can still see a dim image.\n\nhttp://www.screentekinc.com sales laptop screens and has removal instructions on their site as well. The manufacturer will over charge you for the screem, if you do need one and you're no longer under warranty.\n\nGood luck.

Your laptop is a Toshiba and it is not 1337\n\nOh, and monitor is broken.

Does your monitor do or show anything at all? Or is it completely dead. Check the cords and make sure they didnt fall off. When you turn the computer on do you get a boot up screen and then it goes dead? If so the monitor is ok. The monitor driver my be corrupt or deleted itself, or you might have a bad video card. Try this turn the computer and the monitor on and unplug the monitor cord from the back of the computer if the monitor is ok you should get a message on the screen telling you that it is disconnected from the computer, if you get this message then the cord or the video card or driver is bad. If you have a friend with a computer ask them if you can borrow their monitor. Disconnect your monitor and reconnect it using their cord if it still wont work your cord is fine if it works you then need a new cord. If it still wont work connect their monitor and see if it works if it does then you need a new monitor if it does the same thing that yours is doing, then it is something else and not the monitor or the cord. If their monitor doesnt work either then it could be the the video card or the driver. To see if it is the driver or the video card since you cant check it in the device manager because your monitor isnt working do this. Notice where the cord plugs into the back of the computer,open the computer up hopefully you have a plug in video card (plugs in slots on the board and can be removed) the other kind is a onboard video card which is built onto the board. If you have a removeable card be carefull and pull it out of the computer. Start the computer up and let it run for a couple of minutes then turn the computer off this will clear a corrupt driver from the system bios. Turn the computer back on if the card is ok it and the driver is bad it will ask ask you if you want to reinstall the driver click yes it will the ask you from where click MS web site also click on the C drive make sure that you have it so it searches all the C drive. It will then do a search and if it finds the driver it will ask you if you want to install it, click yes, after you are done, restart the computer if the monitor still doesnt work more then likely the video card is shot.You can find a decent one for around 60-70 dollars at Best Buy. If you have an onboard card then you have no choice but to try a new card. There should be a slot on the board for it just make sure when you plug the cord back in to plug it into the new card and not the onboard connection. As for copying the files dumbbutt4321 hit it on the head go to radio shack and by cross over cables they plug into the usb connectors!!\nP.S. once again I have read answers from people that DO NOT KNOW WHAT THEY ARE TALKING ABOUT. You can NOT switch a hardrive from 1 computer to another without formatting it.. The reason being is that EVERY CPU has a unique identifier on it that installs it self into the BIOS and on to the hardrive. It matches the CPU and hardrive together. Because of this a hardrive will not work if you take it out of one computer and put it into another one without formatting the drive. You have to erase that unique identifier off the drive so that when you switch them the CPU will do its thing and put the id on the new drive so it will match up again! I wish that all you BACK YARD so called computer geeks would leave this stuff up to those of us that actually spent months and alot of money going to school to learn computers and and take tests to get certified. All you manage to do is f+ck up the peoples computer more then it is already!!!!!!!                                                                            GOOD LUCK!!!!\n                             ZEUS

First go to control panel > Power Options > Power Schemes > Settings for Home/Office Desk Schemes  and check whether you have activated any auto turn off for HDD or Monitior (say after 10 minutes). \n\nCheck whether you have activated any screen server which gives you a blank screen after certain amount of time.\n\nIf it is not this please make sure your data cable, mouse cable and keyboard cables are properly connected to your system. \n\nMake sure that no automatic shutdown tasks is created earlier.\n\nAlso run a virus scan so as to make sure that there is timer based viruses which activate them selves in a sp. time.

It's a problem with your monitor. \n\nYour pc is actually starting fine, it's the refresh rate that's made the monitor unable to work out what it's supposed to be displaying\n\nSee if you can drop it back down to 60Hz in your display properties in safe mode before reboorting, then presto you should have it back again. \n\nIf that doesn't work I'm not too sure how to do it in Windows, but because I have an old monitor, I've done it the text based way about 0324234234 times in linux.

Uninstall your video card drivers, then reboot, that should set your display back. If not, you probably have the resolution of your monitor set too high for what your graphics card can handle, set it lower. If that doesn't help, you might want to consider a new video card. :)
