Sorry to dig up an old thread, but finding an answer to my problem I think this is the best bet.
I have a rev 2 that according to the ASUS repair centre needed to be replaced as I experienced sporadic touch registrations on the screen from time to time. On-line I could only find the rev 3 digitizer and after reading someone used a .2 to replace a .3 I figured it would work.
So after the long wait finally arrived and I went though the pain-staking process of removing the old LCD and .2 digitizer.
But ever since installing the .3 it detects very little to no input.
I plugged the old one back in and just left it hanging to the side and that seems to be working, but strange no go with the new one.
Someone mentioned a firmware a few posts back, is this something I need to look more into for compatibility with the rev .3?
