You could remove the suspect filter and put in a link to bypass it, just to find whether the rest of the signal path is intact and the switching is correct. But look out for tricks like them using DC paths in filters as part of diode switch networks. These people would do anything to save a resistor.

The last time I changed filter in a TS430S was in the mid 80's so I don't trust memories for specific details.
