Laptop screen flickering in hp laptop. had it for 1 year. screen stays on but flickers black very quickly

The video inverter may be failing, BUT...

More than likely the backlight is failing. If you can still see a VERY faint image on the screen this is almost certainly the problem.This is a very difficult fix. I recommend a replacement LCD.

It MIGHT be a bad lcd cable. With the laptop on, slowly open it from closed to open and back again and see if there is a position where the laptop screen does not flicker or turn off, [or if it does turn off if it turns back on.

If the screen goes COMPLETELY black then your GPU is failing.

Hi Kevin,
My daughter has the same problem with her laptop, do you find that when you move the screen slowly back and forth it either stops or gets worse ?
You will need to take your laptop in to an HP dealer and let them have a look at it.
Regards :)

sir try un-installed your video card then install angain.

you have a problem with your flat it is a cable connecting the monitor to the notebook itself and may be damaged or not fixed in it's place

You may have a faulty inverter or loose power inverter connection. OR
You may have a 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 the monitor up first then the laptop, 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.

If the laptop is under a year old it could still be under warranty and if so I would get it repaired under warranty.

I am sure that the issue is related to the cable that connects to the LCD Display or the LCD Backlight.
There should be some connection shortage because of which the LCD flickers few times as stated by dan231.
I Recommend you to get the Notebook examined as soon as possible before something really goes wrong...

Your inverter board is bad. It is time to change it.
This manual page 152 will show you what is involved.

Hi, i noticed that when I unplugged my HP the screen stopped flickering. I then re-plugged in the power, when to the Nvidia control settings, to PowerMizer, and changed 'ac outlet' to Maximum Power Saving.

Not the world's greatest solution, but hey, working laptop now.

Cheers,
Andy.
