So I lost the sound on my Onkyo 707 today, it was having intermittent drops on video and audio for a few weeks. It has previously been repaired by Onkyo in 2012 out of warranty. After a few minutes of warming up I got video back though.
I tried clearing the receiver and setting up speakers again and had no sound at all from any source, not even test tones in setup. Hooking up the Audyssey mic and got "waiting" flashing on screen.
So I looked at a few posts and videos about reflowing the dts chip and was going to try this myself and buy another receiver if I was unsuccessful. I came across this thread while looking for reflow procedures and though let me try put my serial number in at the Onkyo repair website and see if they will offer a repair again. I was presented with three options trade in for a RZ920 for $699, get a rebate, or get a repair. The initial repair lasted about 5 yrs albeit with video loss issues every once in a while in the last couple years and becoming unbearable in the last few weeks.
I was planning to get a Denon x2400 (deals around $450 popping up from time to time) if the reflow had failed and put the 707 to rest. But now I am wondering of the RZ920 is worth the upgrade, at best this is a $450 discount and at worst $250 considering recent price drops as low as $950 for the RZ.
Currently the 707 is used for home theater in a dedicated room with a 7.1 setup, and I have a couple of in wall speakers lying around which I could possibly hook as the height speakers (in ceiling probably). The display is a 1080p Epson 9350 projector which I don't pan to upgrade anytime soon.
Considering that Onkyo is wiling to repair the 707 again for free I won't try to reflow the chip myself.
So options are:
1. Get the 707 repaired and keep - Free (maybe some costs to mail, but last time around I was able to take it to the local authorized repair shop)
2. Get the 707 repaired and upgrade Denon x2400 - $450-$500, I can find use for the 707 in another room (I would add a heat sink on the 707 of course)
3. Trade the 707 for a RZ920 - $699 (supposed price increase on Jan 1) + shipping, is the RZ920 that much better than a Denon x2400, considering option 2? I see a report above that Onkyo does not want broken units, just the serial number label, I suppose I could try to repair it myself in that case.
Appreciate your thoughts.
