Question about Dell Vostro 1000 Notebook
On a PC screen , the changing colors would be related to a bad connection between the video card and the screen.I suspect that this is the same problem you are experiencing.
While a laptop is not exactly like a computer , the screen cable does the same job. I recently had the same problem with my LCD. The vga cable was broken internally at the back of my screen and the screen kept going different colors uncontrollably. This was fixed by replacing the cable.
If you can open the laptop casing , I would recommend you remove the data cable from the graphics connector to the screen. Inspect the cable for any kinks or damage and reseat it if you can't see any.
This should solve the problem. The only other problems would be a faulty cable , blown component in the screen circuit board and possibly a broken graphics module but this is unlikely to cause this particular problem.
To test the possiblity that the problem is with the graphics adaptor , connect a external screen to the laptop and if this screen displays normally , then we can rule out a graphics card problem.
I don't have a maintenance manual for your laptop so unfortunately I am unable to tell you how to disassemble the laptop and you will need to carefully open it yourself to gain access to these components.
You can order the components you need HERE but I would stop with replacing the screen cable and if that does not solve the problem , it might be better to send it in to a pro as the screen costs about $200.
Please let me know if you need more help or info.
