My screen has a vertical line red-yellow-green from (top to bottom) that stays there. How to fix it?


I do not know any setting that makes a vertical line red-yellow-green from (top to bottom)

If you can find a monitor to connect to and know how to tell the PC to send a signal to it (ie, on a Dell it is Function F8) you can determine if it is your Video card or your screen that has failed. The Video card is part of the Motherboard and very challenging to replace. The LCD screen however is not as expensive and relitively easy to replace. You can watch YouTube videos on how to. A screen can be found at sites like Amazon and EBay.

Vertical lines on the screen, 3 of them, 2 of them left side 1st is green approx. .25 in from the edge, 2nd yellow approx. .5 in from the left, 3rd magenta about 4 in. from the left, all go full length top...


Hi,

This could possibly ne because of the following reasons:

Check if there are any things around that can create a magnetic field,

Also check for the RAM on the laptop. There could be few bad sectors in it which has caused the same.

It could probably tell that either the screen is becomming defective or your video/graphic card is overheating or starting to die/fail.

Please let me know if the provided information has been helpful.
Please rate me if the information provided was able to help you.

Screen appears to have magenta and cyan but lacking yellow. How do I check video cable to screen?


The issue could be related to your graphics adapter or the monitor itself. First try removing the graphics adapter from the Device Manager within your system and rebooting. If this doesn't resolve the issue, you may want to try resetting the monitor itself back to the default factory settings and you can only do this via the buttons directly on the monitor.

there is already a problem with the video card.. for most laptop, they have built in video cards.. so you need to have your laptop checked by a computer technician.. or it would be best to bring it to the manufacturer, so they can install the right drivers for the video card after being fixed..

Does the laptop have integrated or dedicated graphics?
This could be a problem with the graphics drivers. Go to the Toshiba website, and get the latest drivers for you PC, this should solve the problem. If this doesn't solve it, than it looks like the screen / graphics controller / GPU is failing.

Only way you are going to be able to remove this is by replacing the LCD. It is not a huge job, and not extremely expensive if you can do it yourself.

Here is a link to the maint and service guide that should show you removal and replacement of parts.

Yellow stripe down the screen.?


And a good evening to you!
It is possible that you have a bad LCD assembly, or possibly the LCD cable connector is loose. The only way to find out is to remove the LCD assembly from the top cover so that you can access the connector. It is located behind the LCD screen.
If you want a copy of a service manual for the disassembly process, let me know and I'll see what I can do for you.
