Ok, so the too good to be true Boxed PCE Duo I picked up off of ePay may turn out to be to good to be true.
The system came packed with a crusty MONO A/V cable.  Mono.  I didn't even know the PCE had mono mono A/V cables but oh well.  No big deal right, WRONG.  No sound comes through the TV.  I've ordered the $12 Duo AV cable from TZD hoping that will be a fix.  I do get sound from the Head phone jack, so I remain optimistic.
Anyways, does anyone else know of this issue?  Not the melting-heat-sink-sound-melting-soldering-thing thread, but about using a mono A/V cable and it being crusty.
Hopefully my Duo A/V cable fixes the problem.  If not, look for a boxed PCE Duo (matchig numbers) to appear for sale shortly.
In the mean time, it's Dracula X, CF2, and DE2 till I drop!!  Wearing headphones of course...
