Question about Sony VAIO GRV550 Notebook

1 Answer

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

Re: Dark LCD Monitor

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.

if the monitor works but your laptop screen stays dark your laptop screen needs to be replaced .

If the monitor is also dark then the LCD screen is ok but the inverter needs to be replaced

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

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.

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.

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:
