Monitor is blank!!!!

Ok this is an odd..yet weird problem. I'll make this short. Bought laptop. Awhile later..laptop monitor goes blank. SO..i think its broken..i hook in external one. external works fine. I also went into bios and made sure everything was factory set. Oh yes...the laptop monitor is on..but its still black..like a unhooked monitor that is on..but not connected to a computer. So that brightened up something. I went into bios and changed the setting to LCD+RGB. And it semi works now. Laptop monitor shows in bios...and when xp loads. but when im actually in XP it goes blank again ARGH! NOW LISTEN TO THIS! i just installed linux as another OS. And when i'm in linux...everything works PERFECTLY. Laptop monitor shows and everything! But in XP....windows XP that is...it acts like an idiot and stays blank on me..i updated graphics drivers and everything..even formatted and stuff! i dont know what to do...any help? please?!

    Monitor works for 30 seconds, gets shaky and unstable, displays vertical and horizontal lines in color, then goes dark gray and quits. I plug in a Dell lcd ft04 externally, it works perfectly. Have factory loaded windows xp home edition sp2, most updates.

I had the same problem with my Toshiba laptop. I found that by opening or closing the screen slightly (with the computer on), the display suddenly returned and stayed on. I assume there is a problem with the contacts or connection.

Firstly, the LCD+external setting will switch one or the other or both on.

Secondly, if you go into your display properties (or even the advanced page where your video card additional features are) you can usually select which monitor is "primary".

I suspect that your external display is primary, and the LCD screen is not "enabled" or used as part of the desktop.

The settings are all there, it's just a matter of finding them (depending on what video card is in whatever laptop you have)

This might have happened in the first place if you accidentally hit "Fn" and one of the "F" keys up the top. Fn + F6 on my laptop will switch LCD/external monitors on and off. (for example) There is usually a little blue picture on one of the "F" keys to denote that function.

    Oh! Well if that is happening, your screen is pretty much dead. The capacitors that control the panel are probably swolen.



    If you're lucky, you might be able to buy a cheap replacement screen from an auction site and swap it in... otherwise it's just not worth it.

My monitor screen is ok for awhile but suddenly turns a dull yellow color. I just bought it a few months ago.


Hi,
you must adjust the display settings in the software program that was being used to change the display setting.
  • If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
  • Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
  • If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
  • follw the another steps-
  • Replace the monitor power cable.
    1. Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
    2. Replace the video cable. Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
    3. If the monitor does not work after replacing the cables, replace or service the monitor

    I bought a Lenovo S10e last week, for my mum, the monitor was to small for her, so today I bought a Benq g2220hd monitor, problem is that I dont get a signal on the Benq monitor, I did get the windows logo...


    first i would check the compatibility of the monitor to the laptop and see what they say, and if it should work odds are the monitor will have to be set manually through the laptop itself or on the menu of the monitor itself, may take a while playing cat and mouse but im sure you will get it, more then likley from what im understanding its a resolution issue between the monitor and the laptop, especially if you got the windows logo on the boot
