Onkyo TX-DS777 - Answered Questions & Fixed issues

Press VIDEO1 + Speaker A buttons simultaneously.

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

You should be able to do it with the right adapter cable.

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.

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).

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?

I always run the BEST video from any source to the TV first; the best Audio to the BEST audio electronics. If that helps.

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.

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

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

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

The problem is the jumpers in preout front amp in, is where you connect an equalizer or auxiliary amp.You most connect the jumpers if you didnt use the equalizer or the A channel didnt work.

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.

What I've found was bad solder connections on the audio output board.
I Don't know if you are familar with soldering procedures or not.
I would highly suggest not trying it yourself, if you're not a soldering professional. You WILL cause more damage to the unit, ok?
Check with your local audio servicers for estimates.

Good day sir/maam, Yes it can be repaired. if you have plugged in a 110v device to a 220v ac mains, chances are its toast, your onkyo's power transformer is burnt, the repair is replacing the toast power amplifier, or we usually rewind the power transformer specification, after the replacement, you may need to check the power supply section for shorted power regulators, and rectifiers. If you choose to send it for repairs, the service is usually reasonable.

is there a remedy if the wirings and transformer is burned up

i'm afraid that your reciver is dead
sorry
all electrical component's are fried

It seems like the internal fuse to me, too. But you could check to make sure that the receptacle works (maybe you've got a tripped breaker).
The manual also suggests unplugging and re-plugging the unit to clear "external noise" from the "computer circuits," but something tells me that you've already tried that.

do you have speakers hooked up on B?
