sager NP2090 vertical lines on screen

I've had a sager NP2090 for a year and a half now, and I suddenly have vertical lines in the middle of my screen in a variety of colors (green and blue mostly, and occasionally red). They disappear if i flex the side of the LCD one one way and a bunch of them appear when i flex the LCD in the opposite direction. It doesn't show up on a external monitor and it doesn't help if I change gfx drivers or boot into a different OS. If i do some delicate flexing I can make the screen not have any lines, but as soon as I bump the lcd or touch it they'll reappear.

I think there might be some messed up connections somewhere, and I have a copy of the IFL90 dis assembly guide. I'm wondering if it woudl be worth it to take off the LCD and check the connections, and maybe even open up the LCD case itself?? Would this be a possible fix or do I just run the risk of destroying my very pricey laptop?

I'm out of warranty at this point, and I've contacted Sager and they say they'll look at it and won't give me a price quote before they see it, but from what I've heard LCD replacement is expensive, and the LCD seems fine since I can make it look flawless, so it seems like it's a connection problem somewhere in the LCD's panel.

Should I try to fix it myself first or send it in, or has anyone else had issues with this?

Thanks for the help.

 

sounds like it could be the LCD cable or the LCD panel itself.

the replacement of a LCD cable or LCD panel is simple enough... if you are competent with a screw driver.

 

I went ahead and opened up the LCD panel, but all the cables looked OK. Would it be worth it to open up the LCD itself?

It seems like there is pressure on the actual LCD, since when I bend the screen the number of lines changes or even completely disappears. I'm thinking that there must be pressure on the LCD from some source, maybe there is a bit of something stuck inside of the LCD.

However inside the LCD panel and on the LCD itself there is big tape that says DO NOT TOUCH. I'm wondering if it will fry the LCD if I open it up? Or do I just need to be really really careful?

Thanks for the help.

EDIT: In case I can't fix it, does anyone know where I could purchase a replacement screen? I called Sager and they said an out of warranty LCD replacement would cost in the neighborhood of $500!

 

Don't try opening up the lcd itself. If you loosen the screws on the casing that surrounds the lcd and then operate it, do you still get the lines, or not? If you do, then it's unlikely that there's pressure being put on the lcd from some place else.

 

Jubalint, I have the same issue as you I believe. Does you screen turn random colors that jitter randomly. Mainly, its the whites that turn into pinkish colors that are the most noticeable. Well, I nudged the LCD cable around for a little bit (before even removing the lcd screen and determined that it was the cable at fault). Connections were firm on both sides and overall cable condition looked good which was a bit misleading. Probably one of the wires under the insulation either broke and/or has poor conduction, from constant bending of the wire due to opening/closing of the screen. I went ahead and called sager technical support and ordered a new LCD cable which turned out to be $38. I am 99% positive that its the cable. Good luck btw.
