Re: screen keeps flashing intermittently.

There are a number of possible problems.

When the computer is turned on and you wiggle the LCD back and forth and the video becomes corrupted and then if you wiggle it some more and get it to work correclty then you either have a loose video cable connection or a defective video cable. In some cases the LCD will need to be replaced.

If this is not the case then there is the possibility that the video card is bad.

Hp dv6000 laptop screen blurry

Hello Al,

I hate to inform you but the graphics chip in these laptops are known for doing this. HP is aware of that. Every time some one brings me a Hp Dv6000 laptop about 75% of the problem is the system board or overheating issues.

First try cleaning the laptop screen with laptop screen cleaner

Walmart LCD Display Screen Cleaner for TVs Computers and Cameras

if its still blurry connect a external monitor to your laptop to see if the display is blurry on the external monitor (to get to toggle the video from your laptop you will have to press the Fn key + F4)

If its still blurry then its the graphics card or chip needs to be replaced. They are all integrated with the system board / mother board.

If its clear and images are good then the laptop screen will need to be replaced. hope that helps.

I have lenovo screen flickers in every 5minutes...

Failing Inverter An inverter, typically found inside a laptop computer, consists of a small board, which has impregnated electronic circuits stamped on it. Inverters look like thin boards about the of two sticks of chewing gum. The inverter and its bulb control the intensity of the liquid crystal display, which lights the screen monitor. The computer can control the output voltage of the inverter and either lighten or darken the screen. A special type of inverter can adjust the brightness of the screen by using an internal sensor to judge the room brightness, and then adjust the screen accordingly. Failing inverters give off some specific warning signs, which can be recognized by observing different screen characteristics.

Short Intermittent Display Upon turning on the laptop, the screen flashes on in the normal mode for a short period and then blinks to black. A very faint image appears in a dark background, which will be very hard to see almost invisible. After shutting off the laptop and restarting, the same mode occurs, where the screen appears normal for a few seconds then fades to black. This condition points to a failed inverter. To confirm this, plug in an operational external monitor; if the external monitor functions, the inverter has failed. b> Total Blackout with Ghost image b> The laptop turns on, as indicated by the power supply button, but the screen comes up black. The screen comes up black after restart. You might be able to detect a very dim or ghost-like image on the monitor. When you plug in a known functioning external monitor, the external monitor operates normally. This mode of display indicates a failed inverter. b> Long Term Periodic Operation b> With this failure mode, the laptop screen illuminates normally upon start-up and remains that way after several minutes, hours or even days, until it goes very dark again. Brightness controls or restoration attempts do not work. Most often, the screen will function normally with a computer restart, but will eventually return to black. Faint ghost images might appear, as seen in the total blackout mode. b> Dark With Color Variation b> Upon computer start-up, the monitor shows black or dark gray, accompanied by very faint images. The screen might have an intermittent color change, or remain on with a non-standard color variation, like pink or red. b> Auto Control Switch b> If the screen appears black, with no faint or ghost images, look for the lid switch near the back hinge. The switch, when depressed with a closed lid, shuts off the computer and monitor functions. Sometimes the switch becomes stuck in the closed position, disallowing the computer and monitor to turn on when opened. Pushing the switch manually several times can often free it up. If the switch tab has broken or jammed inside the case, it needs replacing. b> Loose Connection In this mode, the display looks normal upon start-up, but tapping the side case of the computer turns the screen black. More tapping results in the screen functioning normally then cutting out again. This condition points to a loose wire connection from the inverter to the LCD backlight lamp, or the video cable. The connectors can be accessed by removing the monitor bezel screws and pulling the plastic retainer off. Both connectors can be cleaned and refitted.

The LCD screen intermittantly flashes

It could be the on/off switch that turns on/off the monitor when you open and close the lid. If the hinges are lose, damaged due to a drop, jar or have dust, dirt, etc. it will get stuck. If you have canned air clean around the hinges. Also there is a ribbon cable behind the monitor and a backlight at the bottom of the monitor. This video will give you the idea:

My computer keeps flashing the blue lights on and off,screen blank,not coming on tried to take battery off hold down start button connect to ac nothing happens same problem

Sounds like video card or video cable is faulty or loose. Is screen always blank no matter what you try? Were you getting intermittent screen flickering. There is a ribbon cable that runs from base to lid that sometimes get worn or loose from constant open/close of the lid. Try cranking lid to different positions while trying to boot up. You maybe able to find a video card under one of the covers on bottom. push card all the way inward to make sure it is seated correctly.

LCD flashes and flickers, partial display of bootup and then black screen

Try the following:

Sometimes when you press and hold the corners of the LCD area (not on the LCD itself, but on the frame), and see if it gives you a picture (or at least flickers when you do so).

My opinion is that your LCD could need rewiring or replacing.
