series of LCD panel replacements epic fail
I am trying to repair a Macbook Air that had broken hinges and severed cables. I ordered a replacement LVDS cable from ebay, which has signal lines for the display and iSight / ambient light sensor. When I put it all together, the original display was all white with faint rainbow colored vertical lines (kind of pastel colored) all over the screen. I was advised by another local repair person that this is a common manufacturer defect of the LCD panel, and the LCD panel also needed to be replaced. I had him test the logic board (I don't know what he did) and he thinks it's fine, and I agree. The display signal coming from the external miniDVI port is great. So since then, I have been through 4 (four) LCD panel replacements and all of them have the same symptom: all white screen with faint rainbow colored vertical lines everywhere.
So I am now going to order another LVDS cable. The question is, how many revisions of this cable (more accurately, this wire harness) are out there, and how do I identify the different ones? If I could get that info, maybe I could prove to the ebay seller that the item I bought was not as described and get a refund.
