On second thought, before doing anything else, check for proper voltages on the 6AG7 demod driver tube V123. If good, check xfmr T114 for continuity on the secondary.
If good, scope the signal coming out of terminals A and D of T114. That's the 3.58 bandpass signal before it's mixed with the 3.58 osc. signal.
