Help with my Yamaha V673 receiver!

sunten1 526 41 June 22, 2016 at 03:17 AM
So a couple days ago I was watching TV and I noticed my speakers making a weird noise. But I was drifting in and out of sleep so I didn't do anything. The next morning I went and played some YouTube through AirPlay for an hour or so. This is when The sound cut out. The YouTube video was playing but nothing was coming out of the speakers. I tried using the on board net radio and the there was no sound as well. I switched to my TV to stream YouTube through that and nothing. I then hooked headphones up to the receiver and again nothing.

Then I unplugged the unit from the wall pushed the power button a few time and let it sit for about 24 hours before plugging it back in. Same thing. No sound.

I did a factory reset per the manual and no sound there either.

I also disconnected all the inputs and outputs except the left and right channel and the audio input and you guessed it. No sound.

I'm assuming my unit is cooked? At this point do I bring it to a shop or start searching for another unit? Can someone make a recommendation on which unit I should go with? Help!

PS I am running Polk Monitor 70 towers (using the bi amp feature in the receiver) Polk CS2 center, Polk Monitor 40s for the rears and 2 Polk W505 subs.

Tough call. Probably cost $200-$300 at least to get it fixed which is about what that unit is worth. If it was me, I'd just get a new one.

Sounds like your network board or digital board went out. If you call Yamaha support, they'll put you through with one of their techs, to help you identify the issue. If the board is still available, you could probably fix it your self for less than $100 -$150. Taking it to a Authorized Yamaha repair center will cost at least $200, maybe more. Personally, I'd start looking for a new receiver cause a lot of the boards replacements are refurbished now.

Here is a good replacement for less than $300. It's one model higher than your previous receiver and several years newer.

Before you completely give up, you can check all of the amp's fuses. It should have several. There may be some user-accessible fuses on the rear panel, or you might need to open the unit up with a screwdriver. There may be some big capacitors inside which can give you a nasty shock if you touch. But otherwise, you should be able to find a few small fuses, which you can test with a voltmeter or a continuity tester.
