LC1552B / 7438 - looks like the main controller. Has
some strange logo I've
never seen before - kind of a _/- (a squared off S?) with a circle
printed over the top.
ITT / 492-5 / 7445 - these appear to be LED drivers. I've never seen a part
number like this. BTW, the "7445" is printed vertically, the rest of the
p/n is printed horizontally (as normal).
The 74xx numbers are most likely date codes.
