Bose AWRC-1P

[Boobtube]

I have an old Bose AWRC-1P radio/cd player that has no audio at the
output. There is audio at the line outs. it seems that the voltage at
pin 7 of the output chip--TDA7375A is going below the threshold voltage
and forcing the chip into mute/standby mode. I have no schematic for this
thing and Bose is very reluctant to offer any assistance that doesn't
require forking over hundreds of dollars. I did try replacing the output
chip and it was working but then when I would turn it off, it would take
longer and longer to come on each time I turned it on again. Now I can
turn it on and wait for hours. It may come on but lately it hasn't. Any
clues as to where to look or does anyone know of an available schematic?

Mail me off-group with a valid address that you know can receive an
attachment of several MB, and I will send you a copy of the service manual,
which has a very good circuit description that should allow you to
troubleshoot the problem.

Arfa,

I have the same issue with a wave radio. Can you hook me up with schematic as well??

thanks,

Matt

HEY I NEED A SCHEMATIC ALSO NO SOUND REPLACED BIG IC's and small caps still no sound
ANYONE HAVE A diagram of parts
