Toshiba lap top half screen rainbow lines


Sounds like the screen is going bad. Isolate the problem by plugging an external monitor to the laptop. Borrow a monitor from a neighbor, friend, relative or co-worker to plug to the laptop. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If the Borrowed monitor does not show the rainbow lines, that proves your video card is ok and the problem is your lcd screen. If the borrowed monitor shows the same rainbow lines it means your video card inside the computer has the issue.

The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

My nikon cool pix has a white line the screen?


Hello Bettylue.

If the line is permanant it is a fault with the lcd screen. If the line shows in the pictures displayed on a different screen the fault is with the lens or other component. LCD screens can be replaced quite easily and have come down in price a lot in the last few years. If you are somewhat handy and feel comfortable opening the camera a little web searching may allow you to do the repair. If you can live with the line and it doesn't show on the pics it will probably last quite a while as it is.

I hope this is of some help... Dale

14 inch monitor starts to show horizontal lines


This is most likely due to pixel degradation. There is no easy way to fix this problem but some have had success with using a pencil and a towel and lightly massaging the screen through the towel with the tip of the pencil.

My screen has a horizontal line through the middle. And sometimes puts vertical lines from there down, and then you cant see anything. Is it the screen that needs to be replaced?


sounds like the LCD panel may need to be replaced. To further check it, try to test if the same issue happens when you connect an external monitor to the laptop. Also, go to the BIOS screen and see if the same line are showing. If no issues with external monitor and line also shows in the BIOS, it would confirm the issue is specific to the LCD of the laptop. If within warranty, you can refer to Acer for repairs and/or replacement. If out of warranty and in doubt, see if you will get other advise from other users, or have a local tech verify it, whichever works for you.

The disc spins but doesn't show anything. It goes straight to the browser and system configuration screen. It acts like there's no disc in it.

My monitor screen is black and the yellow standby light is blinking. I can not get the light to stop blinking or get the monitor to show anything, but a black screen. What can I do to coerrect the problem?


mcdevito75 here, Press the SHIFT key, a screen should come up telling you too click on your user name, left lower side of screen. If this doesn"t work, press the yellow blinking light on the monitor see if picture comes back, then follow the directions. If this doesn"t work, shut computer down with switch on the computer itself. Hope this helps.
