Often DIYers would buy a dozen (or so) of the chips along with the sockets and swap them until the set starts working. When it stops working again, they go through their box of ICs and change them until it starts back up. Often, the previously "bad" IC might work again.
Sony seems to have designed the circuits (running at 250 KHZ) around perfect versions of the IC but any drift of components and it stops working and the manufacturer of the chips doesn't seem to have tight enough production QC.
That said, those ICs usually cause an H-Stop or V-Stop error occasionally but with power supplies running at insane speeds, the Micro is just quessing at times as to the cause of a shutdown.
