Audio receiver repair JVC RX-6010V

[ChadTower]

All of a sudden our main home theater receiver sounds like ---Cleveland steamer---.  I haven't done a full round of tests yet,but from multiple devices (Tivo, DVD player, VCR, Dreamcast) I see the same symptoms.  They ARE all routed through a Pelican switchbox, and I still have to bypass that to test, but as of now it looks like the issue is the receiver.

What I see so far is barely any audio to left front and very scratchy audio to right front.  I still have to find a DVD that can run tests around the rears and center.

The sucker was fine yesterday, we use it a ton, and have been using it for 4-5 years.  Anyone here familiar with audio receivers enough to give me some pointers?  I'm much better at soldering than I was before and repairing a thru plated PCB doesn't scare me.

Blame the pelican first.. unless that receiver has FM, if it does, test it through that..

Turns out to be the receiver, it could be a few things, maybe a blowing cap for the audio digitalizy thingy (no idea what the real name is)..

[ChadTower]

Hooked the Dreamcast directly up to it, same results... swapped speakers around, same results no matter the speakers... definitely the receiver.  The Pelican does not seem to be the issue.

Check for bloated caps, and fuses going out

[ChadTower]

Inline fuses?  Would there be fuses around the outputs?  I haven't opened the thing up yet.

Possibly.. depends on year/make/model/designer... ive seen some stupid fuse placements honestly..

[ChadTower]

well, let's put it this way.  This thing retailed for $170 4 years ago, so I wouldn't expect anything high end in there.

Crack her open..

Will do this weekend.  Gotta clean off the workbench first and it's piled high with crap.

have a good check around the PSU, crackling / distorted sound sometimes indicates a lack of negative supply

Caps or amp ic-you never know dry joints on inputs/outputs

Even if it's only on one output?

[Edgedamage]

Did you check the speaker outputs sometimes the spring loaded connecter gets dirty and causes a bad connection. Also is there pots/volume control for the front speakers?
If so turn off the amp ajust the pots max to mini quickly about 5 times for each pot. Sometimes the pots get dirty and cause audio loss.

[ChadTower]

No pots, not that fancy a receiver.  I think if the connectors were dirty it would have become obvious while I was switching the speakers around (changing which speaker was connected to each terminal)... so that's out too.

If the receiver is only owrth that much, would there be any point in trying to fix it?
Sounds like it had a good run and my just have to go to silicon heaven.

[ChadTower]

I'm probably going to replace it with a refurb Harmon Kardon.

It may actually have gone to Silicon Heaven with all the calculators.

sometimes on 5.1 amps they use seperate supplies for seperate channels, (although thats usually on higher grade amps) my big sony has 5 seperate psu's inside so that a high output on one channel doesnt affect the other channels in any way

[ChadTower]

I'll keep that in mind but would be really surprised if this one was set up with 5 power supplies...

[ChadTower]

Replaced with one of these.
