No RH audio on Sharp 3 in 1 unit.

Hello,

I have a Sharp 3 in 1 unit model no: CD-JX3X(GY). It originally had an
intermittent audio fault which I traced back to dry joints on two IC's
(IC 441 and IC 421) which are connected to a large heat sink. After
re-soldering the dry joints I then noticed that only the left audio
channel worked. Further investigations revealed that IC 441 was blown
so I ordered a new one and replaced it.
However this has not fixed the problem and I still only have audio
from the left hand side. I have checked the head phone jack and tried
all inputs etc, but the problem is the same with all of them. Does
anyone here have any suggestions as to what I can do to fix the
problem. I would have assumed that the blown IC and the lack of RH
audio would have to of been more than
coincidence, but replacing the IC did not fix the problem. Im assuming
that something else may be blown such as a cap or resistor. Any
suggestions?
Thanks in advance,

Troy.
