PS3 400AAA Blu-Ray Drive Main BoardThis is a complete replacement blu-ray drive mainboard for PS3 consoles. With the controller chips dying such as the BD and BA chips these boards can be an ideal solution for repair guys that wish to strip the parts needed for repair on other boards, but can also be used as a total board replacement for a single drive if the problem with an original board can’t be diagnosed or repaired.
The NAND firmware chip is located under the main processor chip on the drive board, we have made a photo below that shows you where it is located. Most people are not flashing right now and just removing the NAND from the old board and having it soldered to this new one. With the price of the complete board being so close to the BD controller IC itself, it can be a good idea to go this way as every single component will be new, which means if there was anything else wrong with the old drive board apart from the common problem being the BD controller IC, you will have it covered, but with saying that a lot of even the professional repair guys will need to send the boards away to a specialist workshop to have the NAND removed and replaced which will raise the cost of the service of course.
