Try cooling down things with freeze spray, or heating up with a hairdryer, to make the problem occur quicker/slower and try to locate a single cause.

The problems with AS15-F are gamma related, and from what I know are permanent. It might be a cold seam somewhere.
Please post some pictures with the boards/bad image.
