Question: Verizon FIOS Remote Control won't turn Onkyo Receiver on We recently got Verizon FIOS for our TV and have tried all remote codes we could find to set up our ONKYO TX-SR674 receiver to work with Verizon's remote control. The remote will turn the receiver off, but won't turn it on. Cannot figure this out. Any thoughts on what we should try??
Document: Fortunately, the TV has a spare HDMI input but it kind of defeats my original purpose to do this.Overall, happy. I am going to try another HDMI cable from a different supplier to see whether that works. If not I will just leave as is.Added information:  Tried a different HDMI cable. Didn't work either. It appears you cannot run HDMI out of a DVD player, into the Onkyo, and out to the TV via HDMI. Component works fine, though.
I recently upgraded to the Onkyo TX-SR674 replacing a 8 year old entry level Harmon Kardon Unit. I felt that the overall features for the price on the 674 could not be beat. Setup was pretty easy. My only complaints are that it seems like it has a little trouble autodetecting which surround sound mode to go into when watching TV, especially when changing from a program to a commercial and when there is a delay between the sound and the video when it is turned on initally.
I purchased the TX-SR674 specifically for the two HDMI inputs - one for DVD, the other for Satellite. This unit replaced an Onkyo TX-DS656, which also performed extremely well. The SR674 is reasonably priced, sounds great, and does what the manufacture claims it can do. What else could you want? The A/V receiver is the cornerstone of your home theater, and the TX-SR674 is rock solid.One caveat though - the remote is not RF like it was with the DS656.
Onkyo remote to control my Hi-Def Toshiba DVD player I should try surfing the net to see if I could Google one up. In my opinion it would seem that newer is not always better with Onkyo.
The Onkyo TX-SR674 is an excellent home theater A/V Receiver, with all of the features I was looking for, with only one exception.....no phono input. However, that was an easy work around with a seperate pre-amp to one of the extra inputs.
I purchased this unit for $399 about a week ago after returning a defective Yamaha 2700 which was double the $$. I've never owned a Onkyo (always denon or Yamaha) but I wanted to give Onkyo a try after all the good reviews and I needed a reciever my wife could figure out without having to read the manual. I can say that I am happy with the purchase! The unit does everthing well and is easy to use/ set up.
My setup:* Receiver: Onkyo TX-SR674. * 5.1 Speaker setup - Polk Audio: Monitor 70 fronts + Monitor 40 Surrounds + CS2 Center + PSW12 Subwoofer.I am thrilled with my new Onkyo TX-SR674. The feature that I love best is the single HDMI out to my TV.
Kept flickering in and out. Debugged it with the Onkyo tech support but we could not resolve it as the Oppo and Dish units are HDCP compatible and the agent said I would just need to ask for an exchange. Could not figure out if it was the HDMI IN or HDMI OUT of the reciever that was messed up. Was able to make it work with the component connection and the video looked great. But I would prefer the HDMI connectivity and eliminate the extra cables.
I have just up-graded to a 40" HD samsung 1080p TV so I had to replace my 2 yr old onkyo 601 "great receiver" with this 674 model mainly for the HDMI switching capabilities, set-up was a little tricky but after an hour I was ready to try the audyssey set up mic. which was very straight forward & accurate Boy was I blown away.
I just hooked this receiver up and it worked great right out of the box. No problems with the automatic speaker set-up. My only complaint is the receiver requires two seperate remote code commands to turn it on and off. As a result I had to get a new remote. This is my first time with anything but Sony, (whose comparable receiver was $300 more).
Answer: Onkyo uses discrete codes for 'on' and 'off', it is not a 'toggle' code like those used by other receiver manufacturers (Sony for example).  So you can program the AUX button on the FiOS remote to turn the receiver on or off but not both.  I use a universal remote with macros programmed to turn all the home theater equipment on and one to turn everything off.
