Thx Lordoftherings, I do have the manual in pdf and was surprised that there is nothing in it that indicates that a factory reset is possible. I'll have to see about the MEM Guard though, hopefully its not only accessible from the remote!
Same for me bro. The manual for most of their receivers, including the RX-V750 (which is the model just before yours) has the reset procedure that I already gave you on my prior post, post #4.
I believe that you can pretty much access al the setup settings from your menus, all from the front panel.
* The Memory Guard has to be disable in order to make some changements in your settings.
But if your receiver was unplugged for more than two days, I believe, it autommatically reset itself to the Default settings, the original ones of when the receiver was first purchased brand new.
The original remote control for your receiver should be easily acquire from your Yamaha dealer service center.
And like I said previously, the best remote for you to get, is the Logitech Harmony 550 Universal remote control. It is easily available online for less than $30, and it contains all the codes for over 500,000 other remote controls, if not much more by now. You'll love it, so as your wife.
And that's also why I gave you Yamaha own phone number from their service center. But you can easily look for the very best one, close to your living area, by simply Google the right combination of words, which I know already you are very well calibrated for that.
I wish you the very best on your quest.
