Windows 7: Dell Latitude D600 Display Flickering (random horizontal lines)

Dell Latitude D600 Display Flickering (random horizontal lines)

Hello all.

I have a Dell Latitude D600 and at random times the display will flicker with horizontal lines. I can sometimes agitate it by gently twisting the LCD and it will flicker. I've done some research before and thought the problem would be the flex video cable, which I ordered and installed, but it still flickers. The LCD looks cosmetically perfect, as well as the inverter. The display backlight isn't flickering, rather there are white lines that flicker randomly, so I don't think it's the inverter.

I hooked it up via VGA to an external machine and only the laptop suffered the flicking so I believe that the graphics card is fine.

Here's a video on what I'm talking about.

Bump. I checked the flex cable connections to both the LCD and motherboard, and they're both fine.

The Dell users forum, Laptop section is probably a good place to try and get help. There are those there familiar with Dell products.

Thanks for your reply. I posted the question there too, but if their online tech support is as bad as their phone support, I'll be redirected 50 times before I get anywhere.

edit: I bought a top case (LCD / Inverter / Flex Cable) from eBay. I'll see how that goes.

The Dell users forum is users helping users, just like this forum. The forum "regulars" help more than Dell tech support does. I used to do a lot of support on that forum (for 10 years) but mostly desktops and not laptops.

I installed the LCD and Inverter and so far so good, no flickering.

Bump, Same problem here. Sorry to revive such an old post but was the problem the panel? I Just tried replacing the WXGA cable but it did not make a difference
