Hello. My name is Michael. I can help you with your question. I am going to check out the video. Just a minute,

Expert:  Michael Hannigan replied 17 days ago.

Thank you. I have seen this happen before. And I'm afraid the news is not good.

Expert:  Michael Hannigan replied 17 days ago.

But you can at least try a reset.

Press "straight" button and hold and then the "on" button
red light shown will go out and a command appear.
If you get that far, hit "Program Right"

If you don't get that far, then one or more of the ICs on the main board is damaged... usually from a power surge.

Customer: replied 17 days ago.
I tried this and nothing.
Red light just turns off and then the display never comes on.
Do you have a schematic of the board to identify what you would recommend changing? I just want to play around with it.
Am I able to test ic while it is on the board?
I think it was definitely a power surge. I was out of town for a few weeks and the protector had a burnt brown area on it...
Assuming I can't fix this, I have a theater room where I use this and we watch a lot of movies. I have 2 rear speakers and then front 2 and center in the wall. Nothing special. Prob $100 or so each.
I had a nice Harmon karden 10" sub, probably overkill.
The room is only about 13x16''. So the sound stays trapped pretty well.
I mainly use the receiver as a switch. Most movies sound good enough. I am not a sound freak where I can tell every distortion with sound.Knowing all of this, are there any receivers and/or sub that you would recommend as a replacement?Thanks
Expert:  Michael Hannigan replied 17 days ago.

Of course, you could always check the capacitors to make sure there are not that are bulging, even slightly. But from what I have seen in the past, this isn't a problem with the power supply or components related to that - I've only ever been able to correct it by replacing the whole main board. Which today wouldn't be worth the cost. I don't know of any way to test the ICs on the board. And I also don't have a schematic for this one. Yamaha used to make basically two classes of products, those that were "non-commissionable" and those that were "commissionable". The latter were all their really good stuff, which is where your receiver falls, and because of the money in those (at least I think), the schematics weren't easy to come by outside of the company.

Hey... I'm a huge fan of Harmon Karden. I wouldn't dissuade you from going with all Harmon! These days, price differences in high end systems aren't as high as they used to be (or, when you're in your twenties, maybe they just seemed bigger).

I think you would be absolutely amazed at the amount of dimension a larger sound system would bring to a 10x13 space. I have about the same size room with a projector on one wall. It only sits a few people, but when I upgraded to 7.1, I was blown away. I didn't even change the speakers - just added some and changed the receiver.

For replacements, I still do love Yamaha. They still have these two classes of products, but it's not always clear which is which. It used to be that you could get the higher end stuff at tweeter and the lower end at big box stores, but that's no longer the case. They're all mixed in together. But the price gives it away. If you ever wonder why there are two Yamaha receivers with similar specs and vastly different prices - that's why. The more expensive one in this case is a superior product. And I will always love Harmon. In fact, that's my favorite, but it's also expensive. If you're using HDMI, you'll definitely want that on the receiver. It's pretty common today, but wasn't several years ago.

Expert:  Michael Hannigan replied 17 days ago.

Sorry... I meant 9.1... when I upgraded, I went from 5.1 to 9.1, which adds ambiance on the sides, and also high and low in the front.

Expert:  Michael Hannigan replied 17 days ago.

For speakers - I have a combination of Bose sound cubes, Infinity, and Alesis for the front low. Bose cubes are one of the best, ***** ***** overpriced. Really overpriced.

Expert:  Michael Hannigan replied 17 days ago.

Infinity is now part of Harman, I believe.

Hi Michael,
I appreciate the answer. I just wanted to get some direction in what you feel would be a fair replacement to that unit.
I already have the 5 speakers built into the walls. To go with a 7.1 or 9.1 would require to add more speakers in the walls or purchase wireless remote speakers. I can't tell the different in sound that well. From looking at receivers, a 9.1 receiver is easly $1000. Then I have to purchase 4 new speakers and I still need to get a sub. When I had my sub, it was definitely too much for the room I have.I was looking at these options, what do you think would be best:

Expert:  Michael Hannigan replied 14 days ago.

You don't need to have all the speakers for the 7.2... you can run anything below what it's made to run. So they can all handle 5.1.

And since I'm partial to Yamaha, I really like the RX-V679BL. You'll see that it comes with the receiver

http://amzn.to/2j6096R

And the options of various speaker packages with it. I'd look at them, but I don't think you need these... I'd rather spend it on the sub..

Wired speaker systtem:

Wireless:

Honestly, I wouldn't touch wireless speakers.

That Onkyo is a beast, but in the environment we're talking about, I don't think it would make a bit of difference.

And this is the subwoofer I really like. I think it's the same one you have listed.

I am good with the sub.
Any chance of a good receive under $600 ;).Thanks.
Expert:  Michael Hannigan replied 13 days ago.

Definitely... the Yamaha.... hmmmm... is this the same one? I think this is less money, no?

http://amzn.to/2jw2kgm

Customer: replied 13 days ago.
This one is different and in my ballpark.
I guess another Yamaha and that Onkyo beast.
I don't know that I need extra speakers. I have 5. Anything else I would have to just hard wire.
Expert:  Michael Hannigan replied 13 days ago.

WEll, we are a little spoiled. 5 is a pretty darn good experience.

Expert:  Michael Hannigan replied 13 days ago.

I see. The last time I linked to the 681, not the 679

Expert:  Michael Hannigan replied 13 days ago.

the 681 is the newer model of the 679
