Laptop screen goes black

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.

there are some steps you should check

1.take out your battery and check whether it is bulged or not..if yes replace your battery
2.switch off it for 24 hour and try switching on again..if the s40 interface has come reset it immediately to make sure no malicious programs are in there.
3.if you could do the second step..please update your phone

it seems the touch part is off center because when i touch the screen it reacts one finger over

is this on the laptop screen or a external monitor?

need make and model of problem laptop

I don't believe there is an actual fix for this. One thing you can do is lower your resolution settings and see if it helps.

please don't forget to rate me.

You need to give me a few more details,is the screen blurry on one side,and brighter on the other?,two, are you using a some special graphics software that might not be ment for your computer,you should plug a monitor into your laptop to see if it gives the same affects,and press the window or function key, and one of the monitor symbols on your keyboard at the same time(,they are coloured the same as the function key),to change your main screen to a plug n play one,if the screen comes up with the same affects then it is a software problem,you might have to uninstall the software that is causing the problem,or two if is comes up perfectly,then it might be a hardware problem,you might have to bring your laptop to a pc mechanic to be degaussed,this puts a charge on your laptop screen and it costs more to do than replace one,most plug and play monitors can degauss them selves,others need to be done manually,unfortunately laptop screens have to be taken apart to be degaussed,i know its silly.if its not blurry then it cant be hardware problem.its one of your graphics settings.

I have the same problem...my Aspire 5630 goes black about once or twice a day and I have to re-start computer...then it wants to disk-check. The fan makes a lot of noise before this happens...could it be the fan overheating?

you have a loose connection, good luck....

the cable is loose! take it down to your local repair man or nerd... it just needs to pe pushed back on.
