So, I've read many of the suggestions here and elsewhere online but can't seem to find an answer specifically for this issue I'm having, so I'm asking.
I have a Dell Latitude E4500 which is basically the only working Windows box I have left. I know it's old and has taken quite a licking over the years but still keeps ticking, until recently that is. Rather abruptly the display just decided to spaz out making the machine unusable. The LCD initially had red and blue lines running across it, a sign of a bad wire I hear, then they stopped for a couple of months, then all of a sudden, the display started flickering and became completely distorted. I used to be able to fix this by upping the refresh rate from 40hz to 60hz, but now does the same at either setting.
At first, I thought it was the GPU as it tends to run hot, but I am able to connect an external monitor and that works just fine, so have ruled that out. Beyond this, my search online has lead me to everything from replacing the entire LCD panel to just replacing the ribbon cable between the GPU and inverter.
My question is this: Does anyone here have experience with LCD displays that may have encountered this problem before and first steps to fixing the issue?
I am primarily a software guy, which is why I'm asking but I don't have any problem taking this thing apart to fix the issue, but would just like some direction from hardware gurus before I do.
Here's a pic of what it looks like now, just to clarify. http://i.imgur.com/eM4RlNo.jpg
My thanks to anyone who can lead me in the right direction to fixing this.
