Sorry for the late responses everyone, was out of town the last week.
: Yes 2 boards were removed and one was added, and they let you keep the old boards. All you do is remove the connectors from the boards, take off a few screws and it's out. New cables come for connecting the new board to the existing other boards, speaker system, etc. You also install some foam pads in specific places and some strips of tape come for securing the cables. The instructions tell you exactly where to put the tape and everything.
Well it says not in stock because it is a special order item, they order it when you place your order. It says ETA of 1/29 as of right now, so that is when you can expect your order if you order today.
Yes he did install a firmware update but it was initiated through the service menu, how to do it yourself is all in the instructions. The only other thing he did was go in the service menu and restore the settings for white balance for each color temp setting to same settings as before the hardware swap. He also entered the serial number and model name in manually through the service menu so it appears in the user screens properly. That's all in the instructions also. You may want to make sure you can access the service menu before ordering, try this perhaps?:
I have scanned the instructions as well as the spec sheet that came with the upgrade, you can grab them here:
