HI.

There can be two reasons why this could happen.
1. The LCD screen might have gone bad.
2. or, There might a problem with your video driver.

To rectify,
If you have an external monitor, you can connect that to the laptop & toggle the display, so that you can see if the display is fine on the other computer.

Hope this helps..
Cheers!! Have a nice day!!!

Hi i have problem with my lenovo g550 ...after turning on ...the screen is white...could be a screen tape?


Welcome to Fixya

Try to perform power drain to the system. Take out the battery and unplug the power from the wall. Press and hold the power button for 15 secs. Plug in the power afapter then trun on the computer.

If same thing will happen, try to use external monitor and connect it to your laptop. If still no display then the problem is the onboard video card. If you get a display using the external monitor then the problem is the LCD. Could be loose flex cable inside.

Thank you for using Fixya!

Lenovo G550 laptop boots with a white screen??


Welcome to Fixya

Sounds like you already have LCD problem. Try to test the issue further. Use an external monitor and plug it to your laptop. If you get a display using the external monitor then the problem is the LCD. If there is no display coming out then the problem is the motherboard.

My Lenovo, G550 turns on every light comes on except the screen the light for the power is on but nothing will get screen on can you help me


Hi eseitz26,

For your G550 issue that no display will show on your screen after turning it on although all the lights are showing there are different reasons why you're getting this issue. The two most common issues are:


(1) The system just needed to be refreshed and reset the BIOS. Don't worry because resetting BIOS is just easy and you can do this on your own. Simply power drain your machine.

Here's how: Shut down your PC >> Remove the battery and unplug AC adapter >> Without any power source press and hold the power button for 15-20 seconds (nothing will happen yet) >> Put back the battery and the charger >> Then, turn on your PC.


(2) The LCD cable from your screen going to the motherboard is loosed, that needed to be repaired or defective, and it needs replacement. For this one, you may contact Lenovo to give you options about the repair.

Well, in some rare cases screen might be also defective and needs replacement. You may also take a look on that possibility.

Hope this helps.

Thank you for using Fixya.

Lines all over screne vertical shuttering


Hi,

Looks like your LCD screen got some dead pixels.

My suggestion would be to bring that laptop to your nearest service center or technician and have them check the monitor.

Am afraid to tell you that most dead pixels are unrepairable, hope that only the connection on the LCD screen are at fault.

Happy to sove your problem!

Thakns for asking Fixya!

On screen thin yellow and blue vertical lines.


Unfortunately the LCD is going faulty.. one or more of the "Driver" transistors that operates the LCD elements RGB, have faulted ON.. perhaps this link may help fix it. Otherwise :( http://www.wikihow.com/Fix-a-Stuck-Pixel-on-an-LCD-Monitor
