Part of the circuit is a stereo multiplexer decoder, that decodes the fm stereo signal, I guess that is what you mean when you talk about capacitor linked to the fm band.
I do not have the sbchematics for this circuit, if you are good at electonics just grab the tester and check the whole circuit. On a radio is not difficult to find a blown capacitor.
Test also the stereo/mono switch.

i have the same problem but my receiver doesn't change sources and its blocked on the last station llistened. the problem appeared when i washed the face of the receiver with a special spray. i think that i have done something very wrong like a short cut in the command processor. any help, please?

You are losing power in the vertical section. This will start with bad capacitors. Pay attention to capacitor (locations) C515, 25 volt@10MF, C423,[email protected], C407,35volts@ 100Mf, and C406,50 volts @1Mf.Please pay attention to any 50 volt 1 MF caps not mentioned. These are located near the audio IC, they are very small as the one mentioned earlier.Also, resolder the vertical IC, as there are rings around the pins at the bottom of the board. Start with these procedures and the picture will return and then sound will be stable. Be very careful when you you remove the capacitors. The traces are very small and delicate and you can destroy the TV. Once again....please very careful when you replace these components. Thanks for asking and show a few hands of support.

The Phono section has a very high level of amplification and so the audio input is very sensitive. So a possible faulty/loose grounding of the input can create a HUM which can be due to even a poor shielding of the input from stray AC factors. So you need to check for the these factors that can bring in the hum , you can confirm by isolating the phono circuit and working to the faulty stage.
Also it can be due to a faulty power supply - non filtering in DC- to the phono preamplifier.Finally faulty capacitors in power and feedback circuits can be a reason- check the negative feedback circuit which can be an op-amp with a feedback , check the capcitors here as a higher amplification can also be a reason.- check the preamp IC.
We could not find an exact match, we think this code will work.
