OR, the Q204 collector is not connected to to the 12 k resistor and the 
base of Q205.

You said you replaced Q204. You could have a bad transistor(new parts can 
be bad), a part soldered poorly, or a transistor soldered in wrong.
Check for broken traces and make sure that the orientation is correct on 
Q204's replacement.
