Hot TC9450AF Controller in Ricoh RW8040A Slimline CDRW

Hi all,
I got a slimline CDRW drive from Ricoh that doesn't show a sign of live.
Someone must have removed a blown fuse and soldered a bridge across the
contact points. I managed to power the drive outside the notebook PC and I
noticed the Toshiba TC9450AF CD-drive controller getting hot. The whole
drive is drawing approx. 1 A at 5 V.

Maybe the chip is dead. Maybe something else is the cause. The PCB is full
of test points and usefull hints so it should be servicable - if I only
had a service manual.

Any ideas?

This is what it looks like:
