Hi MJ, If you run your B speakers you will drop your 2 surrounds as the B speakers are meant to be used in a different room. I would suggest that you give us a call so that we can try some troubleshooting, please call our Product Support Team at 800-229-1687, Thanks, JT

Onkyo TX-DS777 does not retain settings after power loss

No internal battery, a large "SuperCap" on the main board acts as one. Look for C8007, 0.1 F, 5.5V.

Are the speakers selected for A or B or AB check the speakers by using a 1.5 volt batter on the cable going to the speakers, if you get a sound from the speaker, you know they are ok, if not, speakers are faulty.

Cannot turn on by remote controller. Want to

Ok, here is my little spin on remote controls.
Sometimes they can be overloaded with commands and lock up the processor that is inside the unit.
The remote can be saved.
1. Remove the batteries and press every button on the remote control and then install new, not the batteries you took out, but new batteries and see if that works.
2. If step one does not work, then you can remove the batteries and unfold a small paper clip and bend it into a U shape and use it to touch the contacts on both ends of the battery contacts together and clear the memory.
3. Test the remote control, if you have a camcorder or a digital camera, and a cell phone will work. Point the remote at the device and press any button, you should be able to see the IR (Infrared LED) lighting up on the display.
If after all of these procedures are followed and you still do not have command of the device that you need to control. You still have more options.
Either replace the remote control with a new or compatible one, I use 1-800-remotes, www.remotes.com.
Or have the device that you are trying to control diagnosed by a technician and see if the remote IR receiver in the unit has gone bad.
I hope that this helps you with your remote issues and as always, Thank you for using FixYa.

Onkyo TX-DS777 goes straight to protection mode

Hello.You have shorted audio outputs. One of your channels has shorted output transistors. If your unit uses output ICs then one of them is shorted. Both types ( individual transistors or ICs ) are located on the large finned heat sink. The parts are available from http:\\www.tritronicsinc.com. good luck

You don't say if all speakers work with the setup procedure. THAT is step 1. Then try FM as it doesn't require any cabling. Then move on to more complex sources like external analog, then digital (and make sure to assign the ports).

Sound from Onkyo CD player well and fine. Then

What am I missing here?

There are a lot of models mentioned in this post. What are WE discussing?

* A Samsung HT-Z310 is a Home Theater System.

* An Onkyo TX-DS777 is higher-end AV Receiver that DOES have a Video 3 input which accepts composite video and analog audio.

* An Onkyo CD player is irrelevant to the TV sound in any scenario.

* Unnamed TV.

I don't see any path in your narrative that would carry audio TO the TV. Is there an unmentioned HDMI cable in here somewhere? I see no other audio outputs on the HTZ.

Are you running the HT-Z310 through an Onkyo receiver to somewhere (?) else?

Register and download the manual for free at retrevo.com http://www.retrevo.com/support/Samsung-HT-Z310-Home-Theater-Systems-manual/id/23122dj393/t/2/ The fewer hops and inteconnects a given signal experiences between its source and your senses, the better. I always run the BEST video from any source to the TV first; the best Audio to the BEST audio electronics. If that helps.

When I turn on my

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Onkyo tx676 loses its preset radio stations when switched off.

No battery, but there is a 0.1 F supercap on the main board that acts like one. Look for C8007.
