I've seen this problem mentioned before on this and other boards but never with a solution or fix... hoping to have better luck this time.
I just replaced the LCD screen on my Dell 8600 Inspirion with the same model. Now, the LCD only displays a series of solid Red, Green, Blue & white screens.
I can hook up an external monitor and operate the computer just fine.
I took it to a repair shop and after two weeks of no phone calls, I finally called them back and they said they couldn't fix it.
Anyone have an idea on the fix?
