My hp coa-se laptop mdl 661631 fhe screen is so dim u cant see it... how do i fix it?


The image on your screen is made up of two parts the lcd screen that creates the image that you can see dimly and a backlight that shines trough the screen brightening it so you can easily read the screen. In your situation in would appear the backlight bulb is burnt out and needs to be replaced. If your handy this is something you could do yourself a search on google for "backlight" and your specific laptop model will bring up available replacement bulb and quite possible detailed instructions on how to replace

Push the button on the front that says menu. Within that menu you will find the brightness control. Use the other buttons to move through the different menu items until you get to Brightness. Once there push the menu button again and then adjust the brightness with the other buttons.

MY A100 LCD SCREEN IS VERY DIMM WHEN VIEWING DVD howto brighten


You can brighten or dim the LCD screen by pressing the Fn key plus another key with the a sun symbol eg the UP & DOWN arrow keys or one of the F3 to F12 keys - it varies depends upon the model of the laptop.
If you cannot vary the brightness of the LCD screen the you have a faulty backlight.

Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

If you see a dim image or flicking image on the LCD screen it means you have a backlight problem.

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.

MacBook Screen Problem


Hi there
If I understand you correctly from start up the screen is dim but does brighten up after time? But now after start up you are getting a flicker how ever a restart solves this.

On the dimming issue. Check your energy saving settings and brightness key is working OK.

The flickering is a bit of a concern.

Just a couple of questions.
Are there any dead spots on the screen? Areas where there are no pixels.
When you tilt the screen forward and backward, does this effect the brightness or flickering?

I too have the same problem with the same monitor.. tv looks great OSD looks great.. pc is dim.. This has nothing to do with the inverter board or the backlight.. I believe that there is an issue with the components that render the Computer video.
