Compaq Presario R3000 dimmed LCD screen

Had the laptop for 4 years with no problems. Last night I turn on my laptop and the screen is dimmed (about half the usual brightness) and everything seems a bit fuzzy. For example, playing solitaire is now very difficult because trying to read the cards gives me a headache. Messed with the brightness, contrast, gamma, resolution. Had to change the entire display setup to "high contrast", up the brightness and contrast all the way, and increase font and pointer size. So now I can read my screen and it seems to be in focus, but it is still dimmed and seems to get dimmer every time I look at it. I am pretty sure it is a screen problem, but I have no iea what kind of problem or how to fix it. Advice?

If your inverter is good I,de say your backlight is going bad, I just replaced mine in a sony vaio and now it seams to bright.

Problem with my screen


You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the 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 it up, 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.

Compaq Presario R3000 dim screen but not dark


Sounds like the auto-dim in the BIOS is set too low. Fortunately the Compaq R3000 allows you to adjust the brightness right from the keyboard. Hold down the [FN] function key while tapping the [F8] key will brighten the screen, while [FN]-[F7] will dim it. The settings are different for running on AC power and battery, so you must do each individually.

Laptop won't stay on


it might as well be a internal problem related to power or loose contacts with RAM or the power chords internally.
Better to go to the technician in this case.
Your first Battery would have been fine too..

Kees,

It sounds like you have fried motherboard. If that's the case, you have to get it serviced by a place your manufacturer recommends. Sometimes the cost can be greater than just buying a new laptop, so shop around and see what you can find price-wise.

Please let me know if this helps. Good luck!
