Laptop i need some tips. my laptop fell and from that time on the screen turned black but if your going to look closely at the background, images are still present and the laptop is still functioning/running.

It sounds like the screen broke when it fell. You'd need to get the screen repaired. Your best bet is to have someone else do it for you. Search for computer repair in your area. Sometimes places that repair broken cell phone screens can also repair laptop screens.

I had the same problem. While rebooting the laptop the screen would be on for a few seconds after it finished rebooting then the display would go black. If you looked very carefully at the screen you could see the image was there but there was no light behind the screen to make the image visible.

I removed the black plastic display bezel cover that goes around the edge of the display screen to check out the lights and wiring. I found a small magnet that belongs inside the display bezel had fallen out of it's slot in the plastic bezel and was stuck to the inverter pcb (printed cicuit board). To fix this problem I secured the magnet into it's slot inside the display bezel with a bit of glue. After fixing the problem and putting the display bezel back together the laptop worked normally.

The magnet could possibly fall out if the laptop was closed and upside down then dropped on a hard surface. Mine did not feel very secure in the mounting slot which is why I secured it with glue.

This magnet is how the laptop knows the lid is closed. When the laptop is closed the magnet is moved closer to a magnetic switch on the inverter pcb and activates the switch. The laptop thinks it is closed and shuts off the lights behind the display screen. When the magnet fell out of it's slot and stuck to the inverter it activated the magnetic switch all the time whether the laptop was open or closed. This caused the laptop to think it was closed and shut off the lights behind the dispaly screen as soon as the reboot finished.

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.

If you turn the computer ON and you can hear that something's running on the background but there's no display , this is a sign that the screen's FL Inverter (this is the chip that controls the backlight of your LCD) or the LCD screen itself is already wearing out and needs to be replaced. If you can see a background image but there's no backlight - you need to have the FL Inverter replaced. If the screen is all black, you may need to have the LCD screen replaced. If you know your way around the computer, you could order screen replacement here and disassembly guide here.


Good luck.

The Sony has had some problems with the LCD screen since models made about 2004, so if your camera was made since that time.

Since it fell, your going to need to take it apart and unseat and reseat the LCD cable where it connects to the back of the LCD as well as where it connects to the motherboard.

Also unseat and reseat the memory one stick at a time in each slot one at a time and try to turn on the laptop after each reseat.

If those things don't work then that means the motherboard is bad.

you will need the optical unit cleaned, if that does not resolve then the optic unit needs replacing
