Sony MHC-3500 problems

[asbefore]

hi there -- I have an old Sony MHC-3500 mini hifi.
The cassette deck unit is long gone, as is the CD changer - they died a long time ago when the kids were little.

But now I have a pesky problem -- when I play audio through the Phono or Aux connections, I only get the right speaker. You'd think something is wrong with the speaker ---- but when I play radio through the Tuner, I get both right and left.

What can it be?

Thank you!

Hi asbefore...  My first thought would be the selector switch (phono/aux/tuner/etc.).  Try ?giggling? that switch or selecting various different functions ?quickly?.  Deoxit will probably help...

I suggest reversing the cables to see if the problem is your unit or the source component (or the cables)

And the balance control.   While you are in there, just Deoxit all of the switches and pots.

are you guys suggesting I open the unit up and Deoxit from the inside -- or just spray some deoxit on it from the outside without taking it apart?

the other weird thing is that this unit has a "surround" button on the amplifier, despite the fact that it only has connections for two speakers. I suppose it's "fake" surround -- but either way, when I press "Surround",  sound appears in the previously muted left speaker -- but it's not quite balanced.

thank you all!
