We are a JVC ASC, though that may change in the next few months. JVC
does not provide phone-tech assist unless you are in the customers home.
And the times I have talked or emailed them (they take a couple of
days to return email) it has been about useless.
The service manual has a 2002 copy write. I think you could still quote
it...
And I certainly have no objections, nor do I see how JVC could really
object to something they have in black and white.
There procedures are typically, do 1, 2, 3, but first...big help.
