I have a HD500 and a JTV-59 connected by an original Line 6 VDI cable.
All of a sudden there is no sound coming into/out of the HD500. Strangely enough the light of the model switch works (wihout the battery inserted).
I tried with a standard ethernet cable cable with the same result (it is powered through the cable but no sound either).
Somehow the JTV does and/or the HD500 does not work properly.
Any ideas ???
