Yamaha CR-820 Repair: No Output, Tuner shows signal received.

[DaveC]

will give that a look before I do anything. All I have is a couple DVMs

and a transistor checker but I can do quite a bit with this limited test
package!

"Continuity" setting on your DVM is all you'll need, probably (c:

I have an old Yamaha CR-820 receiver/amplifier that no longer has any
sound output. The meters still show signal strenght when a tune across the
AM/FM bands but I get no audio from the speakers or the phone jack. No
hiss. hum, carckle or pops. JUst solid dead silence.

It isn't worth sending out for a shop base repair.

Has anyone has a similar problem? Does anyone know where I can obtain a
schematic or service manual?

Have you plugged in a CD player to it yet?

OK, well that's good to know. The reg didn't actually turn up today, so
hopefully tomorrow. You are right that the error figures do relate to 5v -
I can remember the little Japanese guy that lectured me on it originally,
saying so, but his english was not too good, and I was having enough
trouble just trying to stay with that, let alone the in-depth meaning of
what he was actually saying. I definitely do remember him saying that
there were two different schemes as to how the figure related to 5v
though. Shame really, as he was a very clever guy, and clearly knew these
beasts inside out, but boy, was his lecture hard work to understand, just
purely from the linguistic point of view.

And then, of course, we had Mr Beardy in the class, who stopped the poor
little guy every six sentences, and took him, and the whole class, off on
a tangent about some obscure problem that he'd had 10 years ago, for 15
minutes. I'm sure that you've been there ...

Thanks for confirming my suspicions about the 5v reg - I'll let you know !

Reg chip arrived. Fitted Friday morning. Still running Friday night, so I
guess we got us a result !

Why would anybody plug in a CD player to a broken stereo stupid?

That is what I thiought too. I think the post may have been just a "funny".

Methinks so you can rule out the tuner, If you plug in a CD player and
you hear music, then you can be sure that the tuner is fucked.
But if you don't then you work from there.
