I have the same problem, color and grey/shaded bars switch when I start it up, no video on built-in screen whatsoever except for this test-pattern like random switching image. Now, since an external screen on the display port works just fine, I bet (hope) it's a cable issue. Does anyone know where I could start looking to fix it? It's a 2011 MBP so really phasing out it's lifespan right now, but I'd still like to fix it if possible, if only to give the MBP to a kid or something.

Thanks & cheers!
