YAMI RX-V675 Speakers work, then don't.

[rivrbyte]

Hello,
I have a Yamaha RX-675 (105w per ch) I bought in back 10/9/13. ...As I say that, I think that, wow, this is little aged.
This was under warranty, and the problem then was, "The audio cuts in and out, front channel not working, Both optical digital." It was fixed, they "Reset CPU, Firmware upgrade,electrical part replaced")
Forward to-
Jan. 17, 2018
This is my second Yamaha A/V Receiver, and I added a 6.1 'Hsu Sound' VT12 Ventriloquist Sattelite speakers, 200w Sub. I love em' no problems yet.
It's Crackling, when the volume is turned up. I have to jiggle it, sometimes It can work through a movie, but when I turn it off, it's back to the in, and out, crackling sound, forcing me to resort back to the TV speakers with their mighty 5 watts per channel.
So, now is the time to weigh it out. A new one averages $450-$550, I'm guessing, that's how much I paid.
But, if anyone has success with easily blowing out the dust out from each plug-in, to improve connection, or not really.
The receiver is in a enclosed console, with a back, and i'm sure its all dusted out.
OR
Try to find a local, reasonable, AND honest, electronics repair shop, that won't cost me an arm and a face, to repair it,
OR
Cut my losses and buy a new one?


I looked at the back of the A/V to see if any speaker wires came loose. They all looked fine. Somehow, the Surround kicked in, and the only way to keep using this is to NOT shut off power to the Receiver, only to the TV. This worked fine, until this morning, when I turned on the TV, NO SOUND.
Ususally, I can see all the speakers showing up and active, on the front of the receiver. (2 fronts, one center, two rears, and one surround middle-back, and my 200W Subwoofer, on the 7-Channel audio setting. (I use this for overall TV veiwing, then change it to a BD.
Now I do not see any active speaker channels showing up. I've turned up all the volume to this ZONE 1, (I dont use Zone2) then back down half-way, the volume somewhere in the middle, in the event that this decides to kick in, it would be very loud.

This is a HSU Sound 6.1 Speaker system, which is wired differently from a normal speaker setup. The two FRONTS are connected to the CENTER, then back to the receiver, if I remember correctly. The console where this AV is located has a backing on it that I should have removed for easy access to the back, but dust accumilates rapidly in this console, but now, I need to remove the console away from the wall, to get a better look at the back of the receiver.
This was serviced at TAPS, in Long beach, and they fixed a bad channel, so it has to do with the connections.

But this is weird, that sometimes, all the speakers are clear and disctinct, then other times, it's just silent. Frustrated, I always revert back to the TV SPEAKERS. I cant be thinking about replacing this with another $500 AV receiver. This tells me that the speakers themselves, are working, but it could be the connections themselves.
The TV is mounted on the wall, and the only thing I added was an antenna from the roof, to get local stations, without having to pay for Cable.
what else could be causing no sound at all, if, when the a/v is active, and I dont see the listed 6.1 Speakers?


Any suggestions?
Thanks!

If it was me with the volume crackling noise with turning it up, yeah I would ditch that unit or use it as a garage unit. The surround formats changes about every year now so yep it's lil outdated. If you can swing the coin checkout accessories4less they have killer deals on Yamaha, Denon, Pioneer and Marantz units also Integer, Onkyos, I highly recommended accessories4less. Now hs be you tried other speakers with that unit?

Hello, and thanks,

Hello,
Thanks for all that info.
I haven't tried other speakers, and don't have any extra. The AUDIO OUT /surround sometimes works, all the time, if I leave the receiver on, but if I shut it off along with the TV, then turning it back on takes a while, but it POPS and CRACKLES, coming out of the three.. .Center, and R, L speakers.
The ON-SCREEN Function o the yamaha remote does not work, for me to TEST each channel. I tried to somehow reset the remote, no luck.
So with this intermittant working one minute, then crackles and pops at other times, which channel on the receiver would be suspect? I would hate to go out and buy a new AV, to find out it was the speakers, or the other way around.
But to me, hearing all (6) six channels clear and distinct (even though it's intermittant) really makes me think this is NOT A SPEAKER PROBLEM, but a AV problem.
My Hsu sound speaker configuration is not a basic setup. Although the R,L and middle rear surrounds, plus woffer goes into the AV. The center is hooked up to the Center on AV, but the two front R, and L, plugs into the center speaker, if I remember correctly.
