Just been in chat with a mac technician...hope this helps all. pimp my score :-)
Brandon:
I am doing well. To answer your question, unfortunately I do not have all of the part numbers that are available for the LCD. Apple uses three or four different manufacturers for the LCDs in the MacBooks, and each manufacturer has its own part number. However, they are all interchangable and compatible with each other. We cannot guarantee you will receive the same manufacturer as the one you currently have, but we can guarantee compatibility.
SIMON:
ok so do you know if the lp133wx2-tlc1 from the unibody MacBook Pro fits the MacBook a1342? its confusing as trying to find the right lcd
SIMON:
well one that will fit and work
Brandon:
From what I've been told and what I've seen, the MacBook aluminum Unibody, polycarbonate Unibody, and MacBook Pro 13" Unibody all use the same LCD.
SIMON:
ahh ok because there some confusion as there all diffrent part numbers.. mines lp133wx2-tlg1 and MacBook Pros are lp133wx2-tlc1 and the 13 ends with e1....and seen some unibody models end in tlg2. so its confused the hell out of me which one to order..lol
Brandon:
lol, yeah, what you are seeing (those last two letters and numbers changing) are usually revisions that the manufacturers (LG in particular, as the part number you are referencing is for the LG models) make to the LCD. As long as the main section of the part number stays the same, then they should be all compatible.
SIMON:
brill ok how much is shipping for one to the uk? any idea if i buy from you?
