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.

I have a Compaq Presario R3000 laptop. Is it capable of burning DVD's and if so, do I need additional software. I have made a video with sound on Kizoa and I cannot burn it to a DVD as the program...


According to epinions Your Notebook is NOT capable of burning DVD's. It can only burn CD's.

My laptop Presario R3000 won't turn on


let it sit for awhile. then try to power it on. if it powers up and then suts off again, the processor fan is probably bad and needs to be replaced.

Also, take the battery out and tryy to power it up.

My compaq preasrio r3000 black screen cant conect to an external


have you any other A/V ports out ie Svid etc if so try that via an A/V lead, if that works reset your bios settings to minimal settings, if that doesnt work search the 'net someone somewhere has had the same problem! try shining a flashlight/lamp onto the screen whilst booting up, if you see anything on the screen then your inverter is definatly gone and yes it could still be your inverter! your laptop may have software/hardware issues with an external monitor?

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.

Hi Tom,
It appears without looking at the laptop you have removed or dislogged the cable that goes between the motherboard and the screen. This is not hard to do they are very delicate. The only thing you can do is take it to a qualified service tech. i get these periodically in my shop too. Check the cable before you do so to see if you can reconnect it but be very carefull.
Be mucho blessed,

Compaq Presario R3000 Black Screen with flashing cursor


Lines are the BGA RAM Or VRAM Needing rework.. This will also cause boot issues on these models. Do you ever see the Compaq Logo? Weve repaired a ton of these and class settlement happened for the R3000's regarding the jacks but we could repair the other issue as well. (As well as install a new jack while its here).. HP's reimbursing for these outside repairs.
Good luck!
