I'm working on a Technics stereo system from 1993. It has a separate
stereo tuner amplifier, SA-CH655,a CD changer, SL-CH555, and a stereo
sound processor, SH-CH650. The components are interconnected with a
flat ribbon data cable which connects to each unit in the back. The
problem is that at medium to high volume levels the display will go
blank, the sound will cut out and the unit will just stop working. It
doesn't seem to "power down" because you need to power it down to
"reset" this condition. These people really love this thing and very
much would like to have it repaired but I don't want to make a career
of it either. Does anyone have any experience with this condition on
this model? Thanks, Lenny
