Harald:

This is a guess.  It may be that the chip has too much illumination.
All Silicon transitors are photosensitive.  we had this problem with a
MPC chip two years ago: a shift register did not work properly until a
piece of black tape was placed over the chip stopping the light.  Hope
this might help you.
