Gentlemen,
Your recommendations are appreciated.  I checked the IC joints VERY
carefully for cold joints and bridges.  I reflowed all joints as well.
My leads are long as well.

I have a followup question.  The instructions specifically say NOT to
remove the backing on either side.  My LCD backlight assembly has white
diffusers on both sides (so far so good).  There is, however a SECOND
thin plastic translucent (not white) film as well on top of the assembly
which seems to be removable.  Can I remove this second film?

tnx.
