My laptop's LCD screen turns green. When you press your finger somewhere in the top part of the screen it gets back to normal, but only while you're pressing it. otherwise it turns green and weird.

It's definitely not a virus. The connection between your laptop board and the screen has either been severed or damaged to the point where color is disrupted. I would suggest (hopefully under warranty) getting this fixed before this gets any worse.

This sounds like a problem with the connector, or cable, rather than the LCD screen itself. If the screen is fine while pressing on it, it's probably Ok. My similar problem turned out to be the cable. ifixit.com has great troubleshooting and repair advice. (Your pressing finger getting tired yet?)

You turned on your laptop and horrors upon horrors, the screen is BLACK! You see that the laptop has power but besides that nothing is happening. I want you to know that there is a very good chance you can get out of this situation quickly and without any cost. This fix works on all brands of laptops:


• 1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen. After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up. Replace your battery.

A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode, if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on. To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.
Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard. Press the power button if the screen remains black. Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue. Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue. Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness. Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over. Slide the battery latch to eject the battery. Pull the battery out of its compartment. Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard. Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop. Trace the cable coming from the laptop screen to the connector found beneath the bezel.

Reconnect the display cable to the motherboard if the cable has come loose from the connector.
Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place. Turn the computer back on.

If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective.

If the external monitor works, the LCD screen could be broken.
If the monitor doesn't work, the motherboard or video card might need to be replaced.

Since so many different brands and models of laptops exist, specific causes of a white screen vary from laptop to laptop. The likely cause in most cases of a white screen on a laptop is a connection problem between the LCD screen and the video cable running from the motherboard. The issue can also reside strictly with the motherboard or the screen might contain a defect.

You can diagnose a white screen problem by opening up the laptop display case to determine whether a loose video connection on the back of the LCD screen exists. Reconnecting the video cable should resolve the white screen; a video cable reconnection that does not fix the white screen narrows the root cause to a problem with the motherboard or the screen.

"Motherboard Problems"

The only way to determine if the laptop screen turns white due to a motherboard problem is to test out a different, working LCD screen with the laptop. This requires the user connect the inverter board--the power supply for the LCD back light--and the video cable to the test LCD. If the test LCD works with the motherboard, then the laptop's screen needs replacing; otherwise, a new motherboard is needed because there is no way to replace an integrated graphics card on a laptop motherboard.


Thanks.

Hello,

Since the laptop works fine with an attached monitor, it means the problem is the inverter.

The problem with your laptop screen is that the inverter is malfunctioning, that is why you have those three equal horizontal sections.

Change the inverter of your laptop screen and you will see that the screen will be stable back.

Take care.

A buzz in the sound usually indicates poor grounding somewhere or bad filter caps in the power supply. Lines moving up the screen used to be common in old tube sets, also indicates bad power. Have you opened up the back for a look?

This is its contents without the pictures:


OK, let’s get inside the display assembly.
First of all, turn off the laptop, unplug AC adapter and remove the battery.
The screen bezel* has four screws hidden under for seals. Two rubber seals on the top of the bezel and two plastic seals on the bottom.
You can remove all four screw seals with a sharp object as it shown on the picture below. Glue removed seals somewhere on the bezel so they don’t get lost.
Remove four screws found under seals.
Start remove the screen bezel with your fingers. Proceed slowly while removing the bezel.
Carefully separate the display cover from the screen and access the LCD cable connector
You’ll have to unplug the LCD cable from the screen.
First, unglue the clear sticky tape securing the connection.
Second, unplug the LCD cable from the connector on the screen.
Here’s how you can remove the LCD screen.
Simply remove four screws securing the LCD screen to the display hinge. Remove four more screws from the other side of the screen.
Now you can remove and replace the LCD screen with a new LCD screen.
Put all the screws back in there places

Doesn't sound like a good situation. My knee **** reaction would be to reseat the cable and power to the LCD screen. If that doesn't work, I'd take advantage of the warranty. They might be able to get you up and running in short order.
Hope this helps!
