Wow I got the page right huh? I have a semi photographic memory, so I can remember the strangest things, but it comes in a haze at times.

I just got it through my door earlier today.... man that monster is huge and heavy! Nearly broke my back lugging it up the stairs, and my back is already broken. It's in mint condition... not a scuff or scratch on it!

But anyway, the headphones symbol is engaged. I tried doing a reset, but no go there. I guess I'll have to see how much it'll cost to get it fixed. The previous owner lost the receipt, and he got it from Circuit City before they went under.

Congrats! :) Tell me about it (weight), my back was sore for a week, after carrying it by myself, walking for about 8 city blocks, plus 1/4 mile, before finally getting it home. Total distance: approximatively 1 full mile. :eek:
Try this & see if you can make it.
--> But remember too, I planted trees for just over 30 years, carrying loads of trees from my set of quad-bag, with up to 75 pounds a load, up to 10 or more loads a day, in steep rough slashy terrain, at up to 80 degree angle slope. :eek: And I ain't kidding you either.

* About the headphones jack issue: I wish that I can help you, but I sure hope that you can get it fix. I'm certain that it could be fix.
Do ALL you have to do, just to keep this beauty in reach of your ears and soul.
Call Onkyo, visit your nearest audio repair shop, even call the Pope if you have to.

Bravo!

Since there are no warranty issues, I think there is a good chance you can fix this yourself.

Open the case and find the headphone socket. I'm pretty sure you will find a set of switch contacts that are changed by inserting the 1/4 inch phone jack. Now the jacks come in two types. On some the switch contacts should part or open when the phone jack is inserted, on some they will close.

Insert a phone jack and see which it is. Then see with a continuity meter if the contacts are failing to open when they should or failing to close when they should.

Then if there is a problem, clean and tweak the contacts so they function correctly.

It would be my guess that this switch tells the microprocessor whether the phones are inserted or not. It is pretty hard to conceive of it working any other way.

Problems with switch contacts on 1/4 phone plugs are not at all uncommon, especially if someone inserted something they should not have.

This one might be more promising? I'd PM him, ask for photos.

I simply ran a search with keywords "headphone jack", and there are many hits.

Well so much for it being a cheap fix. It took it to an authorized Onkyo repair center, and it turns out the amp circuit board needs to be replaced. Total repair cost: $223. Ouch....

Wow you got ripped off dude. Completely working units go for around $500 on agon.

I have bought a number of non working units on eBay.

However their are lessons.

You can never know for certain what the problem is, so never buy anything that you are not certain you can fix yourself. The service manuals must be readily available.

Don't give more than $60 for any non working unit.

People buy far too much for non working units.

Let's not be so harsh on this guys.

Even the combined cost is far less than these things cost new. So you still got a great deal. Though I wonder if a second opinion might be warranted here. It sounds suspicious to my ears. I'd take it apart and check it out myself. Check out the headphone contacts as TLS Guy suggested.

I already told the repair center to go ahead and fix it. I didn't do a whole lot of investigating myself when I received the unit. The only thing wrong with it was the receiver thought it always had headphones plugged in. I didn't think it would be that expensive of a fix. I really can't get a second opinion because they're the only local authorized service center, and unfortunately I don't have the knowledge to fix it myself.

Its not a simple world anymore, so the repair center is probably correct.
I bet the headphone amp is an operational amp, with analog CMOS logic built in. They have been around for a long time. Then when the logic detects power from the op amp, a Mosfet switch in the op amp chip lifts the signal from the power amps. It likely has some sort of NAND gate or some type of MOSFET gate. That saves them the cost of connecting switches in the phone circuit. The op amp chip will be tiny, on a crowded board, and surface mount placed by robot. That turns the repair into an expensive board replacement. You run into these unexpected road blocks all the time now.

As you build your HT and go through the usual upgrades and such hold out on this piece until you come full circle and then some as it will surely last you quite awhile and give you excellent service, and you still got a decent deal even with the repair, enjoy your new ONKYO, it's certainly a nice piece.:)

It's a shame too. It turns a seemingly inexpensive fix into an eye-popper.

Thanks, a least it will be "new" or refurbished instead of used, which is the way I look at it. Although it did set me back $200 to where I won't be able to purchase any upgrades for now. So much for getting new speakers and a universal DVD player before X-mas.

Sounds about right. Still it's a good deal actually. Considering they retailed around 1000 new I believe.

I have a brand new sammy bd 1400 in the box for 100.00 dollars if you are interested it will fit the bill nicely, I went the way of HD DVD so never added this in to my set-up.I did watch cars one time on it and thats about it.

Thanks, but I plan finding a used 60GB PS3 for Blu-ray, otherwise I'd take you up on your offer. As far as universal DVD goes, I'm leaning toward a Oppo, although there's still a chance I'll just go with a 480p Sony, like the one I currently have. I'm still debating on that one.
