Having problems with your HP Pavilion dv8000t Notebook ?

Screen is dark, can see images in a sunny room.

\015 Howdy all,\015\012\015\012I have an HP Pavilion dv8000 laptop that I've had for about 3 years, give or take. I was on the laptop today in the early morning, just checking my mail and it was perfect. My battery was low, so the computer went into hibernation mode. I then moved it from my bed to my couch, plugged it in, and then turned it on. Everything was starting up normally, then I noticed that the screen wasn't coming on. Everything else was working, just not the screen. I then saw a tiny flicker of my background, and upon moving the computer to a sunny room, found that the screen was not completely black, it just got very dark. I tried the fn button plus f8, but no luck. I'm not getting how it went all weird in a matter of minutes. Your thoughts? Thanks.\015\012\015\012~Doni\015

Answers :

I see this quite a lot. Sometimes it's a loose connections between the motherboard and the lcd display. Especially if the laptop is 3 or so years old. I'm assuming you did a hard reboot and got the same thing. A lot of time the backlight will give out on olfer laptops and the only thing you can do is replace the lcd display or hook it up to seperate monitor. Two things I can recommend are;
\015\0121. Plug the laptop into a crt or lcd external monitor and see if you get the same thing or if you actually get a good image.
\015\0122. Press [Function] [F4} and see if switching between exteranl and internal monitors makes a difference.
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:

\015\012
    \015\012
  • Screen flashs on red/pink and off. \015\012
  • Picture stays on in red and slowly be come normal. \015\012
  • Picture flickering with dim display. \015\012
  • 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 usually leave my Envision G22LWk LCD on all the time; came into the room today, screen was totally dark (as if "off") but power indicator was lit. Turned monitor off, then back on right away and got a very dim image, esp the top half, for maybe 5 to 10 seconds then entire screen went dark/black again -- can't see any image. again, power indicatorl amp is lit -- monitor is NOT shutting down. so swapped another monitor (old 15" Compaq) which works fine so it's not the video card. tried Envision
