Compaq Presario R3000 backlight problem

I have a 3 year old Compaq Presario R3000. Since last 3 days, it's having an issue with the display. The screen always stay black and the back light never comes on but I can still make out an image on the LCD. It’s dark, but the image is still there.
The laptop is booting properly and I can hear the Windows Startup sound and hardly see the images and my desktop image

Please let me know what could have gone wrong with this and it would be great if you can let me know when I can purchase the parts reqd.

Re: Compaq Presario R3000 backlight problem

I had the same problem and the solution was pretty funny! All it was, was the little thingie that gets pressed down as you close the lid on the laptop got wedged in the hole so it didn't pop out when I opened the lid! Solution......simply pop the thing out with a paper clip!

The screen light may be back, and you might need to buy a new lcd monitor for it, but i would try this first before coming to that conclusion. try pressing the function button (fn) and then pressing the brighter button ( an up arrow with what looks like a sun or a gear.)

If that does not work you might try an fl inverter, before replacing the display.

The inverter provides power to the fl tube that lights up the display.

HP parts surfer can help to find the correct part.

I would recommend sending in for repair unless you feel very confident about taking it apart.

Re: Compaq Presario R3000 backlight problem

I had a problem on a compaq presario r3000, the screen was not showing anything, just black but it responded to power, i could hear the sounds of the fans and the hdd. i dismantled the laptop and blew it using a blower thinking that maybe it had a shot but to no avail, i removed the cd-rom thinking maybe it was causing the problem but it didn't work. after 2 hours on the laptop, i just thought of moving the RAM from under the keyboard to under the laptop and i powered the machine on and it went into windows,
at one time i thought it was the motherboard, the graphics card, the memory, the processor but i didn't have spare components to test with and i was almost giving up, so my guess now is that the RAM slot under the keyboard is damaged.

Presario R3000 display went dark can not see Screen goes black after a few minutes of use. You can see a very faint image after a few seconds, but you must do a soft re-start to bring the screen back....

Defective CCFL backlight may has 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.
  • 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.

My Compaq R3000 does not charge up

The problem might be the battery itself. Four years is a long time for rechargeables. Also, check if the error ocurs when the battery is not in the slot.

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..

Compaq Presario R3000 (intel) 2800 Reset 4 or 5 time a day


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!

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!
