So I just spent a frustrating afternoon fixing a laptop LCD. My daughter dropped her eee pc and broke the screen. She ordered the wrong replacement. After getting screwed on shipping and brokerage fees for the display, a $34 display became $100. I did not want to RMA this new wrong screen since itwould cost more than the display was worth in the first place. I installed the new screen anyway. It even worked except for the backlight.

At this point I figured I had nothing to lose so I pulled the data sheets for both displays, old and new, and compared them.

Old display A089SW01 ?New display B089AW01

The new display had an enable line for the backlight. I put a pullup on the enable line, and now there is light. yay!
