Distortion and flickering on the display

Hello,

Recently I've started seeing flickering and distortion on various parts of the display on my MacBook Pro 2008. The location of the distortion changes from time to time but never goes away completely.

I don't believe that it's related to the video card(s) because I tried connecting it to an external display and mirroring it to that display there is no distortion or flickering on the external display.

Also when I try creating a screenshot it shows up looking perfectly normal in it which leads me to believe that it isn't a software related problem.

Just to clarify this isn't on/off flickering like the the screen turning black and then on again, it just happens in some parts of the screen.

This is exactly what it looks like.

Any ideas ?

Thanks in advance

Best Regards

Your LCD display driver logic is having problems.

Did you bang your system or did something heavy sit on your system?

I would say the easiest way to fix this is to replace the entire display unit. Review the iFixIt Guide on how to do this.

+ I agree with Dan, the simplest fix is to replace the entire display assembly. This is most likely caused driver logic/controller board attached to the LCD or it could be the LVDS/video cable. Replacing the entire display unit replaces both parts. Replacing either alone is not the easiest job in the world. Most people break the glass during their first couple of attempts at the job, bringing up the cost.

I am pretty sure that it's the cable since it only happens to the LCD and not an external display.

I have already replaced the display close to a year ago and I'm not really in the mood to do it again. Think I'll just cut my losses and get myself a new Mac.

This probably isn't the place but any ideas how much I could get for it if I were to sell it ?

It's a 2008 model with 2.8 Ghz Core 2 Duo processor, 4 gigs of RAM, 320GB HDD and an NVIDIA GeForce 9600M GT 512 MB.

Once again thanks for the fast replies, much appreciated.

Best Regards

Well, no, the LCD display has the problem not the cable. The driver logic we are talking about is in the LCD display assembly. If the cable was the cause you would have a linear type of repeated pattern or void across the display Vs a spot area like you have here.

In any case which ever direction you go make sure your laptop case is better padded and/or make sure nothing sits on top of your system as the pressure could explain what caused this damage.

If you replaced your LCD less than a year ago with a new one it should still be under warranty. I'd consider sending it back to them and fixing this.
