First, plug a external monitor and toggle the screen to discard configuration or software problems. If the image displays correctly you have a problem either in the LCD screen or its connection cable.
Open the bezel and check for loose or damaged connection cable. Look specially next to the hinge.
In case the problem is not the cable you might have to get a new LCD. You can have replacement parts and instructions here:

Y compaq pressario v2000 goes from black screen to intermittent normal screen. The black screen is on the computer 80% of the time and then the pics fade in and out


The screen on your laptop goes black after every few seconds.


It resumes after a mouse-click or after a key-press.

Solution


Click on Start --> In search bar, type power options and press Enter.

"Select a power plan" window will be opened.


Click on "Change plan settings" next to "Balanced (recommended)".


In "Turn off the display", select "Never" from the drop-down menu under both the options "On battery" and "Plugged in".


Now click on "Save changes" button.

Screen blacks out while rest is still on, is a dv7-1285dx


This is a backlight issue. Either the HV/backlight board is going bad or the wires that go to it through the hinge is broken/making poor connection.
Rock the screen back and fourth. if it goes on and off, then it is the wires. If not then probabbly the board.
If it is the wires, then you will have to order the screen (off ebay) with the cable (unless you can order just the cable) or you will have to order the backlight board.

Screen problems


Hi:
The next time your laptop screen is messing up, try to hook the laptop up to an external monitor. If the picture is bad on the monitor too, you have a laptop video card issue. If the picture is good on the external monitor, then you have a problem with your laptop LCD/ inverter.

Sony vaio vgn nr160e laptop - no display (intermittent). Attached monitor shows display fine and laptop works fine. Screen used to flicker intermittently (last few days).


You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers 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 replace the CCFL lamp.
To determine if the video card or the LCD is faulty, 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. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Screen flickers on Acer Aspire A150 Netbook


Hello,

It really sounds like you have a short in the ac adapter. Laptops dim the backlight on the screen when on battery power and go full brightness when on AC. I think your adapter is going on and off. When it is on the screen is on full and when it goes off the screen dims down a bit. You could have a bad adapter, most likely, or a bad charging jack in your laptop. Check the adapter first, just use a multimeter set to voltage. Read lead goes to the center pin and black lead goes to the outside metal contact, you should get a reading of 18 to about 26 volts. Move the wire around near the plug that you are holding and keep checking the readout. I think you will find the voltage dropping as you move the wire.

I hope this helps, If so please rate my solution.

I have some problems with the display on laptop averatec 3200 the computer is working fine, but i cant see anything on the display. the display is compleately white wen i turn on the laptop.


Problems are possibly due to wires running through the hinges on the laptop which may cause a connection problem/short. Your right. Over time the hinges which house the wires from your screen to your motherboard can wear out causing the monitor wires to have shorts. You may need to contact a professional to replace the screen or to rewire the set.

There's a small plunger just beyond the keyboard which switches the screen off when you close the laptop, this could be sticking. Failing that check the screen cables are secure, reseat the screen
