... when looking at any of these test images on full brightness? My MBP 13 flickers on 2a and 4a, more so on 4a. My Dell 2007WFP (CCFL backlight) flickers slightly on 7a, my Dell Studio 1537 (LED backlight) flickers pretty bad on 4a, and my brothers $500 Compaq (CCFL backlight) flickers a very tiny bit on 4a.

My early 2009 MBP flickers/pulses much as yours does. In fact, it does this when I am using it at the lower illumination levels even when I am not checking the pixel walk. You might want to pay close attention to see if you are getting a subtle flicker viewing these forum pages. Check it at different brightness levels.

If it is, you should take it in. I brought mine in because I was having this problem (something lots of people have been experiencing) and was told that there is an internal article being distributed to to the Apple Genius bars that there is a glitch in a number of the MBP logic boards that is producing this off frequency flicker.

I'm taking in later this week for repair. We'll see if it improves the pixel walk results. I generally like the screen but the flicker is enough to induce an aneurysm after prolonged exposure.
