My display on my laptop has become tempermental working when it wants to. I have it hooked up to an external monitor because other wise I get nothing but a blank blank screen, however every so often the screen will work. What is causing this?
Usually it is the lcd inverter going bad...if you do a search for your model # and lcd inverter and see if you can find any...also you will be able to very faintly see what is on the screen althought it looks black...if that doesn't work then i may be the backlight in the lcd and a new screen may be needed.
Hope this helps

I have a Sony Vaio pcg-61813M. Thanks.
Hook a spare monitor to the video output of the laptop, if picture okay! the LCD panel display is defective and most be replaced. But if symptom is the same on both screens it indicates a bad Video Graphic Card normally built into the motherboard.
Look for a 9 pin or 15 pin plug on the side of your laptop. You can connect an external monitor to these type of jacks . If the display on the external monitor is clear then your laptop display panel is the culprit.
If the invertor was faulty you would get a picture on the external monitor, assuming that the external monitor and the laptop was configured to work. Check the Fn key and F5 at the same time. That should switch between internal/ external or both displays.
The cable that plugs your monitor into your laptop may have come loose. Follow the link below and follow the directions and see if it gets you anywhere. First try to hook up a second monitor. when you plug in the monitor you will have to press Fn + F4 or something along those lines to get the display on both screens. If the lines show up on the second display then it is the computer that is messed up and you will have to replace it or take it to a pro to have this fixed.
Sounds like you have some internal issues going on with this Laptop! If you are getting the same response when you connect an external monitor, then you more than likely have a few things going on here: A bad VGA port for starters, Issues with the Data card, and your graphic card is cetainly not helping. In addition you may want to check appropriate drivers as they are sometimes updated! But my best guess is that you are having issues internally! That could be costly! Sorry!
