if you're still looking to solve this : replacing the AUO version or the Sony version of the LCD is exactly the same. However, things get more complicated when you had a broken AUO and want to replace it with a SONY LCD, or vice versa, because the flex circuit (visible in step 4 ) is different between a AUO and SONY LCD. So without switching the flex circuit, you will not be able to switch the LCD from a Sony to a AUO or from a AUO to a Sony.
Am I making sense ? There are I think 4 versions in total of all flex circuits + components (according to the service manual) : 1 is unique for the AUO, 1 is for the Sony, and the last 1 is for both, but depending on components soldered onto it, it needs to be used for either AUO or Sony.
Switching to AUO makes sense, because prices for a Sony replacement LCD nowadays will cost you more then the complete camera.
AUO LCD's can be found for about 20 - 40 $ . If only you could get hold of the appropriate flex circuit.
