Unibody 15" MBP 2009
I fixed this problem, it appears to be a loose surface mount chip on the mother board. This happened to me after I inadvertently snapped the lid shut quite heavily.
I noticed that gently squeezing the left hand side of the mbp made the stripes go away. I eventually tracked it down to the chip that is the only one set on the diagonal in this image (at the top of the image and cut off by the edge of the picture) also note the battery has been removed in this image.

The chip has LFXP2-5E printed on it. -made by Lattice semiconductor - some kind of PFU with DSP among other things, thrown in.
I just gently gave the chip a push with my finger - there was a very slight click - the stripes have gone.
It seems that the chip might work its way loose with every bump that the mbp gets, I've had mine for 5 years. eventually the chip must get slightly dislodged then the stripes appear.
Hope that helps

I just gently gave the chip  a push with my finger - there was a very slight click -  the stripes have gone.

It seems that the chip might work its way loose with every bump that the mbp gets I've had mine for 5 years  eventually the chip must get dislodged then the stripes appear.
