As you are probably becoming aware, the "build" quality of these cheap
all-in-one combo units is genuine crap.... no matter what brand it is.
Look for cracked solder joints and faulty interconnects between circuit
boards.... and then consider getting real individual components. At
least with individual components your whole system won't be down as you
repair, replace or upgrade an individual item.
As is usually the case, you get about what you pay for.

I have a Panasonic SA-HT790V combination DVD/VCR/tuner/surround sound
with SB-WA312 "active subwoofer" unit. Recently the sound has begun
to
shut off during relatively louder passages. It is necessary to
either
plug in and remove headphones, or power-cycle the subwoofer unit, to
bring it back.

I suspect that the 5 channel amps are actually a part of this
"subwoofer" unit, as well. At first I wondered if overheating could
be
the culprit, but now I suspect the low-frequency vibration from the
subwoofer is tripping something in the unit.

Is anyone aware of an issue such as this with Panasonic gear? Any
suggestions on where to poke and prod?

Thanks!
