Having problems with your Sony VAIO PCG-K23 Notebook ?

My sony vaio vgn-n365e screen is Dim

\015 I have a sony VAIO, VGN-n365e and my screen has gone dim. I've changed out the inverter(purchased a used one off Ebay) and even went as far as changing the backlight and still nothing....I have a table lamp that I put up to the screen and I can see images on the screen. I have also adjusted the brightness with the function key, but still no luck. I have ran out of ideas and money, and I'm not sure what to do next.....anyone know how to solve this problem....or maybe even troubleshoot my inverter?\015

Answers :

The fault could be a faulty CCFL lamp or inverter.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering 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 replacing the CCFL lamp.
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 and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
