I just bought a new screen on Ebay and installed it with out any difficulty. However on starting it up the top half of the screen is quite bright while the bottom half is completely dark. That disappears and the windows XP screen appears as normal but after approx 35 - 40 secs it disappears and and a bright screen slowly appears with a pattern of faded dots in the background and a few coloured vertical lines running down it. Would anybody please have the remotest idea as to what the problem would be? I have linked it to an external monitor and everything works fine. If it’s not the screen, what else could it be?. Your advice and help would be greatly appreciated.
If you dropped it then it is quite possible that you have loosened a component such as a connector that goes to the laptop screen but not to the external display port. When you check your installation again pay careful attention to make sure that all the connections are good. When you are certain that you have checked everything if it still has the white screen problem then follow Woodchip's advice and return the screen to the eBay supplier.
