Question about IBM ThinkPad T21 2648 Notebook

Light blue color to the screen

Somehow on my HP T21 the screen has a light blue color where the white was normally there. Is there a solution for this? Is the screen going bad?
Also, if the cover is tipped to another angle, then a shadow effect of light blue with a little of the white appears.

    I have the same issue, except on a Dell 5100. Areas that are normally bright white are turquoise, and there are horizontal turquoise lines on tabs and stuff. Also, some areas are flickering like a bad horizontal hold on an old TV.

OK, after diligent searching on the internet, I found several instances where someone suggested that a video cable may have come loose. Before forking out cash for a new screen, I pulled mine apart. Lo and behold, a poorly fitted connection on the back of the LCD - taped into place that way by the technician who built the thing. Why it waited 5 years to fail is beyond me. Anyway, it's back to normal after reseating and taping it back down.

It's possible that the screen is going, it's also possible that the inverter is going. An inverter can cause the same color change problem. It's definitely one of the two.

    One more thing. Check the connections from screen to inverter to board.

Hi. I have hp 6735s laptop and when I move him screen suddenly go black or in rare case white and I need to hold power button to shut down and when I turn him on everything is normal until I move him again...


Hi,

When you say you move him, do you mean lifting the unit and moving to another location or just moving the lid (changing angle of the lid/lcd)?

If changing the angle of the display gives you black/white screen, you may be having problem with the LCD cable, it might be loose or defective. But if moving the unit to another location gives you the black/white screen, one component of the unit might be loose. Either you need to properly reinsert the memory of the harddrive. If these simple steps will not resolve the issue then you might need to check the whole motherboard including the connection to the LCD.

Hope this helps.

I have a HP pavillion dv6 that I've had for about a year and just today while working online the screen suddenly changed colors. It's not inverted but some black colors are a solid red, some whites have...


Hi there,

ASAP (and the caps are intentional) get your laptop connected to an external monitor. If the display is fine on the "big screen", it's most likely you only have a screen inverter/lcd failure. Failing Inverters can cause the effect you're seeing as well as an LCD burn out on the way.

If the displays are identical, then your video card is about to fail.

At least you'll know, and know right away.

Display colors are all wrong


This may have to do with your Windows Theme settings.

Step 1. Right click on your Desktop and click Properties

Step 2. Click on the Themes tab

Step 3. Select a different Theme (try the Classic Theme)

See if that solves your problem.
