Hi guys, few days ago I acquired the boombox in the title from eBay (slovenian seller), posted here because all uf us know that this Nordmende in an aka of the JVC RC 838, even if in a more luxury flavor because the RK 4186 has 6 FM presets (which the JVC does not) and the service manual states it works at 15V (12V for the JVC), so it's more powerful. The unit powers up but the radio doesn't work, I even tried the DIN input but got no sound; playing with the source selector I discovered that moving it slightly from the "radio" position I was able to receive some stations but obviously it's not the correct way to say if the radio could work correctly. Immediately thought that the cause of the radio malfunction was oxidization, so opened the unit and, after removing spider webs and every sort of dead small animals (!) that were inside I tried spraying the source switch multiple times with deoxidizer, unfortunately to no avail even after many dozen movements of the switch itself. Tried even the cassette deck but the motor doesn't seem to be working, I have to clean and investigate further. The boombox is very nice and in good condition (save for the 2 antennas, one missing and the other one broken, but I noticed 2 suitable ones on Aliexpress for little money), so I would like to fix it, maybe one of you has the equivalent JVC model and has already faced this kind of problems. Do you think that source switch oxidization is the cause of the malfunction or should I search for something else?
Thank you very much for every help.
