Google this group for the procedure to turn the speakers back on, easy
to do.

I have replaced several blown speakers, especially in the 175 series,
where someone prior tech bypassed the mute circuit and the constant pop
blew it out. I would recommend against the hack approach.

In particular, I wonder where the audio mute problem is coming from.
I do
not have a chipper check but use a generic programmer and would like
to be
able to salvage service parameters on some EEPROMS and salvage chips
with
the audio mute problem.

I don't keep a selection of the chips in stock anymore and would like
to be
able to turn the sets around faster with less inventory and parts
ordering.

Searched the archives, likely repair groups, and the FAQ and did not
find
anything on the actual addresses of the parameters.
