Hello,

I received a Pioneer VSX-D710S AV receiver that does not have any sound
through the speakers. The headphone jack produces sound. It was working
fine until this happened. Although I am not too technical, I did open
it up to take a look, but I have no idea what I'm looking for. Will
buying the service manual help me at all or should I just bring it to a
technician? Is it even worth fixing or paying to have it fixed?

Thanks for your help,

Josh

To be honest, DC coupled amps like this are not for the faint hearted. They
frequently present a serious repair headache even to those of us experienced
in repairing them. It is almost certainly worth doing, but my honest advice
would be to take it to a repair shop that properly understands these amps,
and let them do it. If you make any inexperienced attempts at trouble
shooting it, you might easily end up damaging it further, and then it might
not be worth repairing ...

Well, I do solder my pinball machine and swap drives/cards/RAM in and
out of my computer, but I was definitely trying to dumb down my question
since this is out of my skill set. I wasn't sure if there was a solution
to this issue that would simply involve swapping out a board. *That* I
can handle.

Any ideas what something like this would cost at a technician? Would it
just be cheaper to get a new receiver?

Thanks again,

Josh

It shouldn't take someone who is properly qualified in repairing this type
of equipment, long to give a valid opinion as to what is wrong with it, so
if you are going to take it to be looked at, pick a place that does do
repairs to AV amps. Pioneer is one of the better makes, and in general,
their equipment is fairly well behaved when it comes to diagnosing and
repairing faults. In my opinion, it would certainly be worth the expense of
getting a proper quote to repair it. What pinball do you have ? I have a
fully restored Williams Cosmic Gunfight from 1982.

I think this may be of the series which had problems with the 2SA1145 and
2SC2705 transistors on the amp boards. Pretty big job - about 20 transistors
are involved.

That is enough to scare me into bringing it in.

I am going to make a new post asking for local shop recommendations.
Thanks.

Sweet! I have Bally World Cup Soccer '94. A completely different pinball
era than your CG, but plays fast and furious. I have learned a lot about
electronics repair (as well as plastic repair and overall pinball
maintenance) in my 4 years of ownership.

I love my CG. It uses the old series 7 CPU. Quite a simple straightforward
beast really. I bought it off a dealer who had rebuilt the playfield, but
couldn't get the CPU going. Paid him 50 quid for it. The CPU problem was
dead simple. The backup battery had leaked, and a couple of pcb tracks had
been eaten through. The game ROM sockets were very poor as well, so I put
some new ones in. When the guy had rebuilt the playfield, he had made many
mistakes, such as switch matrixing diodes in backwards, and the pull and
hold coil connections to one of the flipper solenoids that he had replaced,
were backwards. I had a full service manual for it that I got from a little
company in New York, and also the user and programming book, which has full
diagrams with wire colours for the switch and lamp matrices, and also all of
the solenoid channels. That helped considerably. Once all of that was
sorted, there were a couple of problems with blown transistors in the kicker
drive channels, and a couple of mechanical probs with the jet bumpers. The
final problems were all related to intermittent board interconnects, which
is a known problem with these series 7's, apparently. I finished up hard
wiring across between boards using ribbon cable, to overcome this. Since
then, it has been in more or less continuous use for probably 10 years that
I have had it. I just recently moved it into my conservatory, which has
produced a resurgence in interest from all the family and friends.
