Since all the inputs, except the radio, are working, the problem is not at the main part of the amplifier. The most suspicious point for this kind of problem is the input function switch. Move it many times from any input to radio and back in order to "self-clean" the contacts. Take a look also at the balance knob; it has to be at the center position. Also check the results for various radio stations.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.

The switch is contaminated. Pick up some electronic switch cleaner and spray into the switch. Move the switch back and forth a number of times and that should clear up the problem. Make sure that you get the cleaner that has a lubricant included.

"Opening" ... Please explain what you mean.

Yes if it has a suitable speaker connection available and is nominally 8 ohms impedance Speaker and AV.

Being from 1985 or there abouts, it probably needs some TLC at a Yamaha service centre. May need new capacitors and resolder dry joints for age related issues.

WD-40 ... Very dangerous as it not only flammable when wet but is bad for electrical contacts as it leaves a residue behind that does not conduct electricity very well. Check speaker connections first.

(francais) hello in my issue the probleme was a little resistor r027 it's in this red zone and very ugly. easy to find. a friend was unsolded the resistor and weld a little wire after wash with isopropanole alcool. the resistor test the tension when we plug usb thing. less the resistor the usb ports don't work. you can buy r027 for 2 euros for 100 pieces.... or 2 euros for 5 10 pieces (funny).

Question edited for clarity, full make model (what it is)'. Question moved to Yamaha Audio. It may be sympathetic vibration and is coming from something nearby. Put it on a folded towel or sit in the floor to test it. https://www.google.com/search?q=YST-FSW050+bad+vibration ..

You must repair the amplifier first. Take it to an authorised Yamaha service centre.

Visit 00_HTR-5750_U_EN.book (yamaha.com) and see page 59 (Troubleshooting).
