I decided to clean the inside of my vintage Akai stereo receiver

Why ?

with
some QD Electronic Cleaner that I bought at Ace Hardware today. I
took
the top off and sprayed liberal amounts of the cleaner inside and
let
it dry out. However, when I hooked it back up, the receiver only
comes
on at very low volume. It sounds as if the FM Mute button is stuck
on.
It does the same thing to AM stations as well so maybe the Mute
button
can be ruled out. I plugged in a pair of headphones and it didn't
help.

Any suggestions?

You're a nitwit ?

What on earth gave you such a monumentally bad idea in the first
place ?

A competent tech may be able to recover whatever you've done to it
fortunately.
It won't be cheap though.

I did have a reason for cleaning. I was getting a popping noise from
one
of the channels and I wanted to clean the pots.

Dirty pots aren't a cause of popping I'm afraid !


Apparently just because
it's recommended in the FAQ doesn't mean it's a good idea.

Thanks to everybody for the (ahem) constructive advice.

Does the FAQ advise drenching your gear in solvent ? I doubt it !

Graham

Yes it does. Although the FAQ recommends soaking the equipment in a
solution of Fantastic (not electronic cleaner). See below:

"Eliminating tobacco smoke smell from electronic equipment:

First, unplug it. then open it up as much as possible. get a spray
bottle of Fantastic and cut the strength in half with water.

Put the thing over the kitchen sink and spray away. let it sit for a
minute and watch the yellow nicotine crud slither out. repeat if
necessary you shouldn't even have to do any scrubbing.

Avoid getting the stuff into inaccessible dial spaces, water spots are
inevitable.

Then, and this is very important, use the sink spray to thoroughly, very
thoroughly, rinse any hint of cleaner out. (it is NaOH, most all
cleaners are)

Shake it off, spin it around, whatever, to remove excess water.

Heat your oven to 140 degrees F. put in oven for 2 to 3 hours. use some
kind of metal cookie sheet between it and the oven elements to avoid
radiant melting."

The oven trick is great for mass desoldering SMD parts, I keep an old table
top oven for curing adhesives and other stuff like that and I left a couple
of scrap hard drives in the bottom to space things further from the
elements. Last time I cleaned it out there were little heaps of SMD MOSFETs
& diodes etc fallen off the HDs - all the ones I tested worked fine!
