Can someone tell me the difference between LG LCD panels LP154WP2-TLA1 and the LP154WP3-TLA1? I have a Macbook Pro (A1226) with a broken screen. I dissasembled it and found that I have the LG LP154WP2-TLA1 panel. I have found a couple of the LP154WP3-TLA1 panels at a decent price, but not sure if it is compatable. Also, what is the difference in the TLA1, TLA2, TLA3, and TLA4 models? Are they all compatable with each other? Would any of the other manufacturers panels be compatable with the LP154WP2-TLA1 (Samsung LTN154BT02 or AUO B154PW04)? Thank you!
