Screen sometimes lights up but mostly stays dim


You have a bad connection on the LCD ribbon, or a cracked LCD ribbon, or the Inverter is intermittently faulting, the backlight/circuit is faulting. It is hardly ever the switch....but it is under the end of the screen look for a tiny black stick.

Picture goes dark on different sections of screen intermitently then its ok for a while


Intermittent backlight lamps or backlight inverters.

If this model has an auto-dimming feature, try disabling that feature.

Sony vaio vgn nr160e laptop - no display (intermittent). Attached monitor shows display fine and laptop works fine. Screen used to flicker intermittently (last few days).


You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Dark screen ,fn does not work


I would suggest connecting the laptop to an external monitor, just to make sure that it is all running correctly.

If you can see a very dim image on the screen then the backlight is out. This can be a light problem or the inverter that powers the backlight could be bad. The inverter is not real dificult to change and also is not very expensive. If it is the backlight tho, it is easier to just change out the entire screen.

Hope this helps

Backlight problem


if this is a new laptop, then I am guessing you are using it on battery, and you may have some power save setting turned on that is dimming the screen...

Take a look at your power settings under control panel...
