If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

SOURCE: cant see anything on my sony vaio pcg-72dl screen its just blank

Your backlighting may be out.

Try shining a flashlight onto the screen with the lights off in the room.

If you can vaguely see your desktop on the screen, then your backlighting is out.

Let me know if this works,
Simon.

Hi, If you are able to View the VAIO Logo, then you can Perform Recovery using the Recovery Partition. If the issue still persist then it is required to get the unit serviced. Performing recovery will erase all the Data in the Computer.


If you are not able to view the VAIO Logo, then try disconnecting the Computer from the Power Supply, Remove the Batteries RAM Module from the Computer, then Press and Hold the Power Button for 30 seconds. Now replace the Batteries and AC Power then check. If the issue still persist then it is required to get the unit serviced.

A couple of thing will cause this, The backlighting is going out due to a tiny switch, that controls the light when you open and close the lid. It's located near the hinges, it can get stuck due to dust or a misaligned hinge. Take a look at this: http://www.youtube.com/watch?v=2Yi6GNFcP3w

Sony vaio pcg-2j3l desktop will not power on


Just to clarify, the box (power brick) in the middle of the power cord is the power supply. With that said, there is a light on the box (may be green, blue, or some other color). Does it come on when you plug it in (assuming that the wall outlet or serge protector has power)? If it doesn't then the power cable needs to be replaced. If it does then there is something wrong with either the cable going between the box and the computer, the power connector, or the connector on the computer.

the monitor may be losing the back lite. take a flash light or bright light and shine it at the screen after it goes black. can you see a faint picture? if so the back lite has failed. usually the cost of replacement exceeds the cost of a new monitor but there are a couple of web sites that detail the replacement of the "ccfl" cold cathode flouresecent light.

3 month old Sony Vaio notebook keeps turning off by itself, won't even last more then a couple seconds to a couple minutes, tried system restore and defragmenting, and disk cleaning...still nothing!! could...


Try on the BIOS/System Setup and check if its turning off there as well. To entere there, start your computer up, and when you see the Vaio logo press [Delete] several times. You will see a blue screen or black with information of your computer, leave it there for as long as it takes to shut down, if it doesn't then please let us know.

How can I adjust me laptop's brightness?


You really cannot adjust screen brightness through windows unless you have calibration software that uses a light detecting frame... I had a Sony Vaio PCG-something and Vista really screwed it up as well. Here's the Sony eSupport website where you can enter your model and reinstall some originals drivers for the computer that may restore functionality to your function keys:
http://esupport.sony.com/perl/swu-download.pl?upd_id=2207&SMB=YES

Some things you can do to save battery power: turn of your wireless if you're not using it (there's usually a wifi switch on most laptops, turn it off), set your screen saver to come on as quickly as possible, run as few programs as possible and try to avoid graphic-intense programs.
