screen flicker MacBook Air Mid 2012

crwdns2931729:0crwdne2931729:0:

I hope you have advise on my following issue. I have a Macbook Air mid 2012 out of garantee.

I use it with bootcamp to either run it in Win 7 or Mavericks.

On both OS the screen will start to flicker randomely. More on Mavericks then on Win 7. Also it did happen with previous versions of OS X.

The lower I set the resolution the less issues I get, but still they do occur. Could the LCD cable be the pulprit here or does this sound like a graphic chip/mainboard issue? What can be replaced with the air?

Did you get your system wet or sit it down in a puddle? I would pull the cover off and do an inspection. What do you see? Post a good picture or two here for us to see.

Update

It doesn't take much moisture to effect things. I would still look for corrosion around the LVDS connector on the main logic board as I've seen that before.

If you connect an external monitor to your system do you encounter the same issue? If not then you should focus your efforts on the LCD logic. That would be the LCD panel, LDVS cable and its connections; and the main logic board. As you noted the flickering is less after the system has been on for awhile I would suspect the WLED driver could have a cold solder joint.
