Normally you cant view these florescent lights for backlighting. Has your display lid cracked open to reveal them? Also I have never seen where you can see thru the display itself to see the backlighting bulbs? I have seen before where damaged laptop displays look bleached out before as the result of a good drop or after being sat on by accident as one client presented to me. Display acts like it was delaminated causing everything to be bleached out and blury.
Is there a way you can take a picture of what you are seeing to attach here in a post, so we can observe exactly what you are seeing?
