Question about Sony VAIO GRV550 Notebook

Dark LCD Monitor

The monitor on my laptop is very very dark. I can connect a remote monitor and use the unit that way just fine. If I turn the LCD screen towards a light source while using the laptop as a PC, I can see ghost images of programs that I may be using or the icons on my desktop. This tends to make me believe that the LCD monitor is not bad and that it is some other issue. Can anyone advise please. Signed, Working in the dark

    Bogdan,

    Are you reference to the inverter being replaced? I am looking to have the work done by my office's IT guy, but I'll need to know what it is that exactly needs to be replaced.

From what I understand there may be a problem with the power circuitry used to light up a small fluorescent light that is the actual light source for the display. The TFT display itself doesn't produce it's own light, and if you point an external light source to the display and see program windows & other things the display itself is fine. Your problem can be solved with relative ease, but only in a computer service because it demands some components to be changed.

    Yes, sorry for the bad english. This Inverter is a small device that raises the tension values to something like couple hundred volts needed to power the florescent tube.If it fail, the fluorescent light doesn't turn on or is very dim. The inverter can be found either near the display itseft (in the diplay lid) or on the mainboard. This varies from one model to another. It can be recognized by some specific inductances and the dc/ac transformer used in it. If I were to take a guess, I will search it in the display lid first.

In all likely hood, you have a loose connection or a worn LCD cable. This is a common failure in all laptops. If it is a loose connection, re-seating the connectors on both ends of the cable will cure this. If the cable has broken wires in it, it will have to be replaced. i would suggest a knowledgeable person or pro to tackle this for you.

Monitor has developed a permanent dark turquoise hue.


Did you ever try the original monitor on another machine. If the new monitor is displaying the same symptoms as the old one then your video card is the culprit.

The screen on my laptop computer has become dark. If I shine a light on the screen I can barely see the display and if I connect an external monitor to the computer I get a display on the remote monitor....


The LCD display connection is loose. Try reconnecting this and the display will be fine. The connection should be at the top of the base right above the keyboard under the plastics.

Monitor light is almost out, but laptop still functions fine.


Sounds like either the Backlight or the LCD inverter is bad, if you hear a high pitched whine it is the inverter, if it is just dark it is more than likely the LCD, check out ebay for a replacement...

Hope this helps.

Monitor keeps going dark


It sounds like a LCD backlight problem. Bring it to an authorized repair shop.

Screen wont light up



Try connecting an external monitor to the Dell Inspiron 2200. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor display is dark, problem is with either the video card or motherboard located inside your laptop.
Here’s a link to disassemble the LCD unit: http://support.dell.com/support/edocs/systems/ins2200/en/SM/display.htm#1084976

Monitor too dark....


Usually every laptop has the option of adjusting the screen brightness as you would want the screen to be pretty dim when running on battery to conserve battery life.
First thing to check would be just that.
