decoder gone bad on Yamaha RX-V595?

[thatLADude]

I bought a Yamaha RX-V595 receiver back in Nov 1998.

Recently I had to move it around a little when I bought a new media
center cabinet for my living room and needed to reinstall all my
components.

I get all the connections back to what they were and everything works
fine except.... whenever I select the optical digital stream for say,
my DVD player or digital cable box, the receiver shuts off by itself
right as I switch the input source.

However, whenever I select another type of digital signal process
effect, like "rock concert" or "concert hall" I can use the DVD player
or digital cable box fine.

From this I assume that the Dolby Digital decoder inside the receiver
has gone bad. I checked the speaker setting on the back as well, and
it's set properly for my speakers.

Is there anything else I can do besides look for a repair shop or sell
it on Ebay? I hate to sell it since a lot of the newer digital
receivers don't have phono inputs and I don't like the idea of having
to buy a separate phono amp....

TIA.

Most likely induced problem - wiring errors.

When you say "shuts off" do you mean powers itself down?

What happens when you select a digital input with no inputs of any kind
attached to the receiver?

This would be with an analog input, right?

In general, the same electronics, the same chips implement both Dolby
Digital and digital effects.

But is there a chance that a strand of speaker cabling is grounding out
someplace?

I wouldn't worry about the cost of a low-cost but reasonble phono amp.

Do all of the non-digital inputs work properly?

Have you changed the outlets that the DVD player or digital cable box or
receiver plug into?

Does this mean that only that one or two inputs are affected, or that when
you turned the receiver back on it functioned normally on those inputs?

The Yamaha has some rather sophisticated diagnostic software, intended for
repair technicians. I hesitate to give out this info, but the worst that
could probably happen is that you would have to re-enter all your user
settings if you re-initialize the unit.
It is possible to cancel the protection function during the test, (deeper
into the menus) so in rare cases an amp channel could fail if the problem
were a bad bias transistor, etc.

Just to check the protection history, press and hold "FM-AM" and "Input
Mode" simultaneously, then press the "Standby/On key.

The display should either say NO PROTECT (unlikely), PS and a percent
value(unlikely), I Protect (possible) or DC (more likely) and give a
percent.

At this point press the Standby/On switch again to cancel test mode.

My guess is that for some reason there is a DC shift at the moment you first
switch to that source. Could be a bad decoder IC or switch IC.

I cant offer the solution that you are looking for but...
I also have the RX-V595 but I never received the correct remote. I got one
that is very very close, but stupid things like DSP button labels are off by
1 space... anyway, I'd either sell you mine & upgrade myself or buy your
remote if you find yours is not able to be repaired. Either way, I'd be
happy.

This one has already been fixed. His speaker wires were the problem, it
seems.
