    About 2 months ago the front display on mine just quit. I couldn't figure it out. Well...a month later I turned it on...and I only clicked once (it usually clicks twice) and no sound. So I called around and got some estimates...$75 to $125 an Hour. Plus parts.
    Well...I was reading a Smarthome for Dummies book last night. :D
    Well.... :D I Think I Fried It! I was reading about Impedance. Uh Oh!

    I had 2 speakers wired through one terminal. I think it overheated.
    I took it apart just kinda poking around. I took off the front panel and The plastic behind the display was melted!

    Now...It this a fixable problem or should I buy a new receiver?

    :rolleyes:

    When you wire two (or more) speakers in parallel into a single terminal pair, you reduce the impedance as seen by the amp by half the sum of the speaker ratings. (in parallel, 6Ω+6Ω=3Ω ) This results in a troubling doubling of current draw, which, in turn, will fry your finals and cook your goose

    Don't spend money on a new a/v receiver until you purchase, read and understand the book "A/V Receivers for Dummies".

    Ok, Ok...Very Funny...I know I'm an Idiot. I just didn't think about it at the time. Is it fixable?

    I have a question...Can you put say...speakers with an impedance of 8 with a receiver that handles 6?

    I have a Sony system (part of my HTIB). This one has 90 more watts than mine, which sounds really great in my small old living room. :)

    HOWEVER, you might want to notice how many inputs there are, cuz this will be important. ;) Go down to CC and physically look at it yourself, and think about how many components you have. If any components have to share inputs, this can be tricky. :yesman: Also consider expansion possibilities. If you ever want to have speakers somewhere else in the house or outside (I know, I never did either until about a couple weeks ago :rolleyes: ), you'll really want to look for a receiver with A/B speaker outputs.

    Also, what Nick said. :D

    Well...I only really need 1 input...all of my audio goes through my TV then there is an output on my TV...That way when I switch video I don't have to switch an Audio receiver too.

    By the way...that system will have to do...I'm a little strapped for cash right now.

    Has anyone ever told you that you are just a wee bit impulsive? Your original post asking for guidance has been up for less than 12 hours. You can't even wait for the advice you ask for. One characteristic of maturity is possessing the ability to delay gratification.

    If you are "a little strapped for cash", as you say, should you really be considering spending $200 on an inadequate receiver? Your TV has sound? Use it and put off buying something you obviously can't afford.

    Oh, I forgot, you're probably going to charge it, thereby adding to your previously mentioned onerous credit card debt load. :nono2:

    Go figure. :rolleyes:

    It would make ME happy if you hooked up your 811 straight to this receiver via toslink, thereby enjoying the wonderful DD you get from your HD Pak. :)

    (And for all you 811 DD nay-sayers out there, yes it will work! :mad: DD only quits working in the expensive receivers! :yesman: :p )

    Your response sounds exactly like my teenage granddaughter. She's 15

    Frankly, I really don't care what you do. It's your freakin' life. You're free to screw it up any stupid way you see fit, but if you're not interested in at least listening to the advice you ask for, just don't come here asking for help. If you won't listen, we can't help you.

    Probably, with intensive, long-term therapy. Your Onkyo, on the other hand, is fried.

    Ok here's what I would personally recommend. Your Onkyo is fried and would probably cost more money to repair than it is actually worth unless you have one of their flagship models which I don't think that particular model is in this case. However I would stay far, far away from Sony products. About the only model line from them that is worth a damn is their ES line and that's vastly overpriced anyways. Here are some reasonably budget priced receivers:

    1) Harman Kardon AVR-235 details
    2) Onkyo TX-SR602 details

    I would also recommend running all of your audio and video through the receiver instead of the TV. You get much better sound that way and believe it or not it makes switching that much easier. You simply switch through each input on the the receiver and leave your TV on component or S-video or whatever you have the receiver's monitor out hooked into at all times.
