I have now changed the screen on my ProBook 4530s LY475EA (bought in June 2012). Here is my experience:
I bought a AUO B156HW01v5 (Glossy) from LaptopScreen.com after the opening post recommended that site. It arrived about 5-6 days later here in Norway and to my surprise there were no heavy taxing or something similar. I bought the HD+ connector 646274-001 from a guy called "taschablair" on Ebay who sells these worldwide, I bet he is around here as he mentions "ProBook Hackintosh Compatible" in the title, and if you are, again thank you very much. He shipped quickly as well and the cable arrived 7-8 days after purchase.
These items were bought 1 1/2 month ago or so, I was planning on doing a lasercut of the backplate when doing this to get a glowing Apple together with a original MacBook Pro plexiglass Apple logo part i bought from another store, but due to the place I was planning to do it at had a fire very recently (ironically due to the lasercutting machine) they could not help me with that task at the moment and I decided to just install the screen and do the cutting some other time.
It took me 3 hours to install from starting to find the correct screwdriver to firing up the ProBook. I installed the 1080p DSDT beforehand. The only problem I had was that I apparently did not have a T8 screwdriver and I didn't see that until I had disassembled half of it and was ready to remove the top. I used a small flat screwdriver which worked, but was not optimal for it. I do not recommend using a flat screwdriver, go buy a T8 if you have to.
Other than that it worked out pretty well, I messed up some of the cables' positioning which I needed to reposition, but other than that no huge problems. It worked perfectly on the first try.
And as for the screen, let me tell you
it is GLORIOUS. But I would not recommend anyone who isn't comfortable with screws or PC hardware to attempt it alone. Anyone who has some experience with it and are not afraid of screwing the thing apart, then do yourself a favor and replace that old horrible screen.
Thanks everyone, you've been a great help.
