Sharp GF-9090 low sound problem

[Remi]

Hi,

I'm trying to fix this awesome sharp ghettoblaster and I'm having a problem.
The sound from the radio works very well but when I try with a cassette, there is no sound anymore. There are very slightly the sounds of the cassette but the volume button has no effect.

Here is a video showing the problem :

If anyone knows what's wrong, i need some help

Thank you,

Sorry for my English I am French.

It could be due to a dirty function switch. I would clean the tape/radio/line in function switch with Deoxit FaderLube 5.

Ok i cleaned all switchs with iso alcool and it fix the problem.
Thank you
