Onkyo TX-SR876 front left channel not working

[Aharami]

My ARV's (Onkyo TX-SR876) front left channel is not working anymore. Thinking about trying to repair it myself as after shipping to closest Onkyo authorized service center and their diagnostic charge, I'd be out almost $200 before they make any repairs.

Wondering if anyone here has any experience repairing a broken channel on an AVR.

Obvious suggestion, but did you check the A/B output settings?

I see it has pre-out, if the front channel works through that, you can plug everything through a 7 channel amp. Maybe but a old 7 channel AVR which accepts multi-in/DVD-in, that would cost less than $100

yea checked all possible settings. It's definitely the FL channel as it remains silent in the level calibration setting (no static noise).

That's a notable solution, and I'll employ that if all else fails, but I'd rather repair the AVR than entering in more components between the source and the speakers.

Yeah, I am a cheap person, who likes cheap solution, have no regard for elegance and aesthetics :biggrin:, good luck!

You can repair it yourself if you know how to use a multimeter and are a wiz at soldering. Receivers the past 15 years have so much functionality that the parts are small and tightly packed. However, if you don't have both, your local repair shop can do basic diagnosis to give you a better estimate of price.

In almost all cases, including what my buddy does, chances are they'll charge you half the cost of a new replacement, regardless of the fix. Only way to get it less is to find a kind one of one who you know. If you do they'll charge you something under $100 mainly for labor and diagnosis. This is all assuming that the fix is a simple, single component, which is usually is.

Best of luck.

You do know for sure that your left speaker and it's cable are good?

Or speaker for that matter, for mice love to go in them and chew up wires

 

[Aharami]

not the cable or the speaker. double checked

Have you tried another speaker on that channel or swapped the speaker wires around, to confirm the amps dead on the receiver end?

It could be a fuse on the receiver. It might be an easily replaceable one, or it might be soldered on the board someplace.

If you discover the amps good, and the wiring to the speaker looks good, then I would inspect the speaker very carefully. Gain access to the speakers, cross overs and/or circuit board on the speaker itself. Sometimes those can go bad somehow, and it might even have a fuse on it, too. Also, a lot of speakers have a lot of push on connectors inside the cabinets. Over time due to vibrations, they might slide completely off. A dab of solder can fix that problem pretty easily.
