Do I need my logic board replaced (again) or could this be something else?

I have a 2011 macbook pro, I know they have been prone to logic board issues and I already had to get the logic board replaced for erratic graphics behaviour a year ago, but now, a new issue has emerged and I am not sure if it is also logic board related. Sometimes when I switch or launch applications, the screen starts turning to a blue tinge.

I downloaded this gfxcardstatus app that I found and discovered that anytime I switched to using discrete only, the 'AMD' graphics, it triggered the issue and my screen turns blue, but when I am in dynamic mode and switches back to intel, everything returns to normal.

Is this a sign of another faulty logic board?

Has anyone else had this happen?

It's the same thing again.

You don't need that app to switch to discrete only, though. That function is built into Systen Preferences under Power Saving.

The logic board apple replaced has the same problem the old bad one did. The problem is NOT the logic board but rather a certain capacitor ON the logic board. Apple never discovered the problem. Bad apple.
