How do i fix my LCD on my laptop?


Hi,
this sounds like your laptop's back light system has a loose connection, try moving the screen around, if the lights flash, it has a loose connection.
Good luck!

HP DV1000 screen too dim


The 4 most common problems with dim lcd's on a laptop are boken screens, bad power inverter, bad florescent bulbs or a broken cable.

You can test the power inverter with a meter.

There should be 2 bulbs. If your screen is dim and your inverter is good and you can still make out what is on the screen, you probably have a bad bulb. If you can't determine which bulb is bad you'll have to replace both.

In my opinion, the easiest way to handle this is to replace the whole screen. Yes, it's more exspensive, but consider that it is most likely to fix your problem. A replacement screen comes with the power inverter, both bulbs, and the cable; already assembled and ready to install.

Laptop keeps shutting off. DV1490US. There is power in the case but not in the screen. I press the on button fo a while until all the lights go off inthe laptop and repress the same button. Sometimes...


If you hear the hard drive spinning and you think Windows is working but you can't see an image then :-
You could have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
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.

Power issues on HP DV1000


It is possible you have two dud batteries. Recharageable batteries have a limited life, they have a finite number of charge and discharge cycles.
With the battery removed and only the power supply connected and the laptop powered up, when you touch the connector on the laptop and the laptop does not shut down then the laptop connector is OK.

If you can verify your new battery is OK the the fault could be the power supply adapter, if may not produce enought current to run and charge the battery. Try charging the battery overnight by turning off the laptop and leaving on the mains t charge. Borrow a mains adapter and test it on your computer.

You can also check the BIOS setting for power management, ie. hibernate, low power shut down etc.

Screen flickers


If light is good and picture flickers, then it is either a bad LCD ribbon cable, or cable not well placed into connector, or a bad LCD display, usually it is the cable.
If picture flickers like light is dimming out and coming back, then it is the LCD lamp, probably in need of replacement.
In some rare case a faulty Video card is causing the problem.
Usually to fix this you need to take apart LCD display and upper laptop plate, to reveal the display cable.

Screen problem Hp dv1000


The main two causes for this, are the inverter, which supplies the screen with the proper amount of power in order to function correctly, or the screen. If the inverter isn't puting out enough power it will cause the screen to darken or black out completely. Start by checking the screen connections. If all the connection are properly seated, the it's either the inverter or the screen it self.

HP Pavillion power link blinks


aa505 -

I can almost guarantee you this is an issue with the power jack on the laptop's motherboard. Even though it may not appear to be loose, its most likely the solder connection on the motherboard has broken, only allowing intermittent connection when the laptop is in /just/ the right position.

It'd be best to get this looked at sooner rather than later, preferrably if the computer is still under warranty. The connection will steadily decline, until the laptop is unusable.

Otherwise, let me know if you want to get rid of the system! I have a system, almost exactly the same model, that I need parts for!

Hope this helps!

Hp Laptop screen flicker


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.
