RCA rt2770 keeps going back to factory settings while in standby
I've tried talking (through email) to RCA w/o an answer. Will probably call them tomorrow but really don't want to have to send it to them because it's somehow defective. Anyone know why it might be doing this?

Re: RCA rt2770 keeps going back to factory settings while...
By going back to factory settings do you mean when you program radio stations into memory presets, they're erased when you turn the unit on? if that's whats happening, the problem could be with a battery that may be in the unit. alot of electronic devices have a battery inside that should last for years [or forever] that keeps the memory of everything
stored for when the unit is unplugged.this battery [or the unit itself] maybe defective.if you do talk to rca, ask them if there is a battery.maybe the manual even mentions it. you probably can't change it yourself.

First, disconnect it and let it run with no input. Problem here is that it probably has an auto-turnoff and will shut off. My bet is that either your connection wiring is faulty and/or your amp is sending down either RF or DC signals. I would get it close to the amp with another connection cable and check... Good Luck !
what kind of conections do you have on the back of the sub you should either have RCA connections or just one RCA connection or a place for speaker wire to plug directly into it. IF you have RCA connections in back i would use those they will connect directly to your system if your system had and a sub pre out on it read your manual and follow those instructions as well it will help
Although most of my background is in car audio & acoustics, I did have a thought or two about some tests you can do.
DO THIS AT YOUR OWN RISK OF ELECTROCUTION - Have you tried checking the speaker terminals with a voltmeter while the unit is plugged in? I,ve seen solid state amps (both car & home amps do this) kind of lock up and send constant line voltage to the sub. In some cases the sub snaps instantly, high power subs may not. I've used power from a 110v wall outlet to show off some high SPL systems I've built (very painful 60hz earthquakes). So be careful at the sub terminal it may have some voltage at it.-(If it does you probably know the rest of my answer.)- If so the sub will most likely be wasted and fused voice coils are also common when this happens.
If everything checks out okay there (make sure to check if the subs resistance is at spec while you're there) use the voltmeter and start poking around the audio side of things both on the powered sub and RCA's. You may even find a easy problem on RCA cables. Also can/did you plug the RCA's into a known source, to check their output. Most home audio is 1.5v max but some can go as high as 8v max or so. Also don't be afraid to check the simplest of items like source buttons, specifically the tape monitor buttons. My equipment has these such tape functions with little or no indication as to weather or not they are active, and not being plugged into anything you get no sound. I hope I gave some idea's you may not have tried, your fellow Audiophile-
This system does not need a dvd to work but you can attach one. go to page 26 of your tv owners manual. on the far right side of the picture you will see a red and white jack call rca. use a rca patch cord and connect to these jacks on the tv and to the same jacks on your home theater system where it says aux on the back. to hear the tv through the surround, set the system to aux. the only bad thing about vizio is when it goes bad, you have to ship it back to the manufactorer because it is made only for walmart and there are not factory authorized service centers except the factory. Steve, good luck
I was able to take care of this issue by talking to Onkyo tech support. They diagnosed over the phone and concluded that the receiver set the volume for the sub way too low (-12), therefore sub was not receiving the input and was doing what it was supposed to be doing. They walked me through manually increasing the volume and now everything works great.
Good luck! I hope this helps.
The receiver automatic speaker set-up set the sub volume at -12 and since it was not getting any signals from the receiver it was doing what it is supposed to be doing (going to the standby mode). This was troubleshooted by Onkyo tech support on a Sunday. All the best about Onkyo customer support.
telll sterio use sub out and remix on in settings menu on steiro ok also does it have speaker wires in and out use them off fornts ch from sterio then back up throw sub to fronts set cross over on 100 or so
This is RCA's on line PDF manual for the rt2770. http://support.rcaaudiovideo.com/manual.aspx?product=212 The rear panel has every known hookup plus fiber optics.
I have a Question? does your rt2770 volume numbers go all the way from 0 minimum to 50 maximum, mine only goes to 41 and it does not say maximum?
