Unfortunately, tuning/IF problems are some of the hardest ones to debug, even with something like a B&K 1077b television analyst or the like, no easy task at all.

You might want to start with a voltage check at the tuner plug, working back through the IF stages 1-2-3. looking at grid, plate & cathode voltages, that may tell you something.

But if tuning / IF is out of alignment, there is little to do other then hope to find someone with a sweep marker generator setup, and who knows how to use it.
