This one has me STUMPED! Harman Kardon Eight Twenty Tuner Repair

Need tools? Here's a video showing what I use (with links!): https://youtu.be/MLK649c1_fM This Harman Kardon Eight Twenty (820) Stereo Receiver had no signal coming from FM - only static. I checked all of the voltages mentioned in the service manual on the IF board and everything checked out. The tuner cap seems to be having an issue, even though I desoldered and tested every resistor and transistor in the assembly. What do you think could be wrong?
